RAMIE ("BOEHMERIA NIVEA (L) GRAND")

"Ramie" has been an important crop for many centuries in China and Japan, and is one of the oldest known fibers. Being native to East Asia, it also grows in a variety of regions with climates ranging from tropical to temperate.

Ramie is a tall, slender herb with stems that reach up to 3 meters in height.

The coarse layer contains fibers that are superior to other natural fibers, in length and strength. Ramie has great potential to become a major industrial plantation and cash-generating crop in many tropical and subtropical locations.

Today's market demands that any new plant fiber possess extraordinary qualities. Ramie certainly does.

Ramie fibers are long (20 to 40 CM), durable and lustrous. They have eight times the tensile strength of cotton and seven times that of silk. For some strange reason, the resistance increases by about 60% when wet. They are also more resistant to chemicals and decay than most other plant fibers.

Ramie can be used for clothing, fabrics, upholstery, furniture coverings, ropes, twine, and potatoes. Ramie fibers also "breathe," meaning they absorb and release moisture quickly.

Ramie is a perennial plant that is propagated by division of plant stems; the planting of seeds and the stakes are Jambi. acceptable methods.

The plant is relatively free of charge. Little cultivation care is needed, except to inhibit weeds or weeds until the plant itself grows and removes or hides them.

ORIGIN AND DISTRIBUTION

Its origin dates back more than 4,000 years; the mummies of the pharaohs of ancient Egypt have been preserved until then wrapped in ramie cloth, however, since time immemorial, it was known in Java and the Malaysian islands, from where it is believed to originate; Sumatra, Bomeo, Celebes, Moluccas, China, India, Indonesia, Japan, Indochina, the Philippines and Formosa. It has spread to Belgium, Algeria, Spain, Germany, Florida ((UAL Brazil, Argentina, Cuba, Ecuador and the Dominican Republic.

There is a writing, the only one of Etruscan origin in Egypt, which has been preserved because it was written on ramie TV. The same resides in the national museum of Zagreb.

In the time of Napoleon Bonaparte, ramie was introduced to France. The technical name of ramie to our pride was born in Santo Domingo in 1757, that is, 224 years old, when the Austrian Nicolas Joseph Jacquin published his famous work: "Enumerativo Plantación Quas en Insulis Caribaesis Detextis", which Boehmeria Nivea called it in honor to the Salesian Boehmer author of the first European book on the industrialization of ramie.

In Haiti in the 1940s, there was the largest ramie crop in the world on the Dauphine plantation, half a mile from the Dominican border, near Manzanillo.

VARIETIES

Although there are many varieties of ramie, only a few are used commercially based on their high production, the amount of fiber, resistance to pests and their ease of harvesting and processing.

Some of the best known varieties worldwide are: Murakami, Miyazaki 110 and 112, is the most tropical; Sainkeinseishin, Kumaoto and the Hakuri.

In Colombia there is the Romelia variety, which has given good results in the form of forage, since it provides protein foods (18 to 25%) of high quality and digestibility (83 to 86%), which results up to three times with higher amount of protein than alfalfa.

In northern Panama and Sao Paulo, Brazil, the predominant commercial varieties are Miyazaki - 112, and Murakami.

In studies that have been carried out by the Instituto Agronómico Do Panamá (IAPR) together with Toyosen Pesquisa Agrícola (TPA), in Brazil the possibility of adaptation of other national and foreign varieties under edaphoclimatic conditions in the north of Panama is being evaluated .

RAMIE AS AN ORNAMENTAL PLANT

Ramie is a species of the urticaceae family of Asian origin. A textile fiber is obtained from its bark. In the Far East it is used as an ornamental plant.

It reaches a height of between 1 and 2.5 meters, the leaf is heart-shaped, 7 to 15 cm wide and 7 to 15 cm long, whitish and hairy on the underside.

RAMIE IN THE DOMINICAN REPUBLIC

Ramie is a plant that, despite being originated from Mainland China, has been acclimatized in American, tropical and subtropical regions.

Our country can cultivate ramie, since it meets the minimum conditions and requirements for the exploitation and commercialization of this urticacea; The only thing missing is the provision to establish it in different areas, since there is an acclimatized variety and the countries that demand it, such as Japan.

We consider it convenient for our country to plant this textile plant since for about a century we have been committed to its exploitation and the variety B. Nivea Tenacissima has recently been acclimatized.

We also buy other textile fibers abroad that can very well be substituted by Ramie, at the same time that we have minimal experience of cultivation and a Dominican company, Ramírez Valdez y Asociados, was established in January 1980. , C x A., based in Santo Domingo, which aims to promote, industrialize and commercialize textile plants, especially ramie.

THE NAME WAS BORN IN THE DOMINICAN REPUBLIC

We make the exception that the technical name of ramie, to our pride, was born in Santo Domingo in 1757, when the Austrian Nicolás loseph Jaccuin published his famous "Enumerative Plantarum, Quas en Insulis Carubaeis Derrotis", which he calls it Bohemia nívea, in honor of Salesiano Boehmer, author of the first European book on the industrialization of ramie. Ramie is a plant native to China and India, perfectly acclimated to our territory.


The agricultural technician Víctor Ramírez, in love with the land and with a desire to contribute to the common good, has had a project for 46 years on this plant. He tells that the hero Gregorio Luperón made ramie planting experiments in the country in 1882 and Rafael Leónidas Trujillo Molina in 1960.

Since 1962 Ramírez has maintained research and experiments and fields of ramie rhizomes.

It says that "we make the exception that the technical name of ramie was born in Santo Domingo in 1757, when the Austrian Nicolás Joseph Jaquin published his famous Enumerative Plantarum, Quas en Insulls Carubaels Detextis, which he named Bohemia Nivea in honor of to the Salesian Boehmer, author of the first European book on ramie industrialization".

He maintains that this plant processed as flour contains in stabilized form vitamins, proteins and minerals in a well-balanced ration by nature.

Research and experiments have done the following with ramie:

  • The fiber has been processed to make tablecloths, hammocks, cloths, dolls and others;
  • Animal feed in general (feed, forage and flour);
  • Syrup has been obtained;
  • Food for human consumption has been obtained;
  • Paper has been produced and
  • Food mixed with another plant has been prepared for malnourished children and pregnant mothers.

These experiments have been carried out at the Dominican Institute of Technology (INDOTEC), today the Institute for Innovation in Biotechnology and Industry (IIBI), the Dominican Agribusiness Board (JAD), Central Veterinary Laboratory and USDA, according to Ramírez, who says he has evidence of those investigations.

He explains that in his ramie VIR, S.A. project He has had collaboration with those institutions, with former President Hipólito Mejía, when he was Secretary of Agriculture in 1978, and with Heriberto de Castro, Claudio Caamaño, Margarita Peralta, Nelson Rodríguez, Barbarin Magallanes, César Sandino de Jesús and others.

He explains that as an experiment he has planted ramie in Villa Mella, the capital and in Dajabón, and that he is willing to hand over his project to the Government to develop it. He complains that the authorities have not been interested in this project, despite the fact that ramie has been found to have 28% protein that is used to feed birds, pigs, cattle, horses and other animals.

BACKGROUND OF RAMIE IN DOM REP

On December 16, 1982, the Puertoplateño newspaper "El porvenir" stated that they had carried out acclimatization studies of ramie in our country, and that General Gregorio Luperón, hero of our restoration, had the land prepared to start planting and introduce this important agro-industrial line, however, his ideas in this regard were cut short by the political problems that were experienced at that time.

Days later, on January 20, 1883, "El Porvenir again made reference to ramie, echoing a French newspaper, which said that" the economic solution for its colonies in the Caribbean is the cultivation of ramie. Faced with the evident crisis in the Sugar Industry, the Puerto Plata newspaper concluded: "Ramie is a plant that brings the steam that touches Samaná to Santo Domingo on January 26; two machines will arrive shortly to exploit the maguey, while the ramie ". The same newspaper spoke about ramie as of October 1888. "The order, from Santo Domingo, recommended the convenience of growing ramie in the country.

It provided data on how the land should be prepared for exploitation, agronomic care and all forms of cultivation.

During the months of the year 1955, Generalissimo Rafael Leónidas Trujillo ordered new experiments with Ramie, which did not give the expected results, since the appropriate varieties were not brought to the country.

It is really only 80 years after the first Dominican attempts that the government decides in 1961 to solve the problem when it invites a ramie specialist. From this official invitation comes the continuous bio-organic process of degumming ramie stems, without prior decortication. The process yielded results, one million ramie bushes were planted in 14 localities of the country, and politics intervened a little later, a turbulent time that did not allow construction works in agriculture.

Even so, the results obtained in the Dom. Rep. were put into practice in Nigeria, the Ivory Coast, the Philippines, Taiwan, Japan and India.

In the early years of the 1960s, a Dominican, Mr. Víctor Ivan Ramirez Valdez, accompanied by several Dominican technicians, completed an investigation in Bonao. They immediately prepared a report on said work for the commercial company SOPODECO, which is in the archives of the Chamber of Commerce and Industry in Santo Domingo. Mr. Ramirez Valdez in the mid-1960s, proposed a project for the exploitation of Ramie to the agricultural bank of the Dominican Republic, in which he specified that a thousand Dominican agro-industrial workers could find work.

In 1978, Ramírez Valdez also planted 40 tasks of ramie in Villa Mella, Santo Domingo, with the initial purpose of creating the source, that is, the seedbed from which the plants that will be used for the exploitation of this textile plant are obtained. and its commercialization in our country.

It can be summarized that we Dominicans have spent about a century engaged in the exploitation of ramie cultivation.

PROMOTERS IN DOM REP

  • General Gregorio Luperón - Year 1882 - 1884
  • Era of Trujillo - Year 1955 - 1960
  • Víctor Ramírez - Year 1962 - 2021

PROMOTES RAMIUM CULTIVATION IN DR

Although the country has not taken advantage of the benefits provided by the Ramie plant, its main promoter Víctor Ramírez affirms that, if there is political will, Dominicans can achieve excellent advantages from its cultivation and contribute to lower production costs of egg, milk and meat.

Ramírez's intention is for this plant to develop, providing the resources for its production, whether in the public or private sector, after considering that "if I have to provide the seeds that are needed, I would. What happens is that We are not like the Orientals and we want the things of today for tomorrow, we want the benefit to be immediate, and that is not possible because everything in life has its process ...

Since 1882, dozens of studies of Ramie have been carried out in the country, and it is believed that its cultivation would influence agricultural and industrial development, especially for its multiple uses: textile, forage or animal feed, paper pulp, pressed wood, organic fertilizers and others.

Ramírez, president of the Ramie project, explains that he has experienced that this plant is tasteful, rich in vitamin A and fat, as well as calcium and fibers.

He affirms that Ramie could be the answer to the many years spent in the search for a low-cost nutritious food that serves to control growth and animal reproduction that meets the needs of economic benefits.

Since 1962, Ramírez began his research to develop Ramie's production. In that year he verified the advantages to cultivate it, but their complaints have been frequent due to the political instability of that time, as well as the lack of cooperation from governments to their Initiative.

He explains that after several studies he found that the leaves have 28% protein, which is an incentive for animal food and even human food. In addition, the plant contains the eight amino acids that the human body needs.

"We have to be on the lookout for when the country is afraid if tourism, free zones or remittances decrease, and look for the guarantee in diversifying and developing technified agriculture", he said.

A project with Ramie as raw material "is what one has fought for since 1962, it is what we need", complaining about the little support it has received. "When we talk with people who have the potential to develop the project, that is a lot of hugs, I congratulate you, but no support, not even from governments."

He highlights that his investigations have been linked to institutions such as the former lndotec, Veterinary Laboratory, the Autonomous University of Santo Domingo (UASD), the Dominican Agribusiness Board (JAD) and others.

BOTANICAL DESCRIPTION - GENERAL MORPHOLOGY

The Plant

Ramie is a plant that has superior properties to cotton, hemp, linen and silk. The plantation can last from 25 to 40 tall; In Latin American countries it has lasted 10 years, producing very well one hectare can produce 10 times more fiber annually than one of cotton.

If compared with hemp, flax and jute, they have the advantages in that it is not necessary to macerate it, being able to shred the green stem, still freshly cut and in the same plantation.

It is a perennial, erect, branched, tall and shrubby textile plant, or herbaceous, not tropical but a plant of warm climates, with permanent underground strains that protrude from the ground and from which herbaceous channels grow, measuring 1 to 25 meters in height, size acquired at 45 to 60 days, with 1 6 2 CM in diameter. The aerial shoots or herbaceous canes, which constitute the commercial part, are cylindrical and unbranched.

STEM STRUCTURE

When the young Ramie stem is cut, the epidermis appears first, with very thick external walls and numerous unicellular hairs. The epidermis disappears when the shoots are mature, and is replaced by the peridermis, made up of 4 to 6 layers of dry cells; Below the peridermis there is a continuous zone of collenchyma, followed by another of parenchyma, which contains many crystals and starch grains.

This layer, 3 to 5 cells thick, surrounds the cylinder of fibers, form. in turn, by polygonal cells, with very thick walls, whose length from 10 to 25 mm is much greater than the other fibers.

According to the age of the plant, there are 3 to 6 rows of cells in the cylinder which is not solid, but is irregularly interrupted by parenchyma masses, where the other phloem tissues are found.

The central part of the stem is occupied by the wood or xylem and by a highly developed pith. The parenchyma tissue that surrounds the fiber zone contains gums that adhere strongly to the fiber walls; To remove them and leave the fiber clean, it must be subjected to a mechanical or chemical washing process, which is very expensive and delicate.

When the stems are cut during the growth period, shoots emerge that produce new stems, which allows two or three cuts per year, and up to four when conditions are exceptionally favorable.

THE LEAVES

The alternate, broad, oval, or heart-shaped leaves with the long pointed apex, with serrated edges, are 5 to 15 cm wide; they are green on the upper side and whitish on the underside as in the case of boebmeria nivea, and green on both sides and with a more vigorous growth as in boebmeria utilis or B. n. Tenacissima, which is more tropical than the first.

INFLORESCENCE

Ramie flowers are small and yellow in color. Its inflorescences are auxiliary panicles that arise from the upper nodes of the same stem, in two clusters: the staminiferous flowers p that carry pollen, form the cluster that arises from the lower part of the axil of the stem, which are distinguished by their larger size ; while the pistillate flowers are tubular and hairy and are divided into 2 or 4 teeth; they are green, yellow or red, depending on the variety; the unicellular ovary ends in a long style with hairs on only one side.

Boebmeria nivea flowers deeply and produces a high number of fertile seeds with high germination power.

FRUIT AND SEMIUAS

The fruit is an achene, with many brown-yellow seeds, 1 mm wide, pear-shaped, spindle-shaped, and usually permanently embedded in the calyx.

The spice B. nivea can produce 50 grams of seeds per plant.

FRUIT CHARACTERISTICS

The well degummed ramie fiber is snow-white, shiny like natural silk, light, long, fine, almost transparent, and extremely firm. When washing fabrics, it does not shrink or stretch; it does not rot, floats on water and mixes very well with fine fabrics; it is also suitable for thick fabrics, which resist abuse; quickly absorbs sweat, dries easily and resists washing unlimitedly.

Ramie is called "the queen of textiles"; it absorbs dyes very well and retains them. It has been considered the strongest of all vegetable fibers and is also called "Vegetable Silk".

In addition, it resists seawater very well and is waterproof, hence its various marine and related uses.

To establish the importance of the good qualities of ramie over other fibers, we share the following conclusions:

  • The fiber of ramie is longer and more uniform than that of flax and hemp.
  • It offers greater tensile strength than all other textile fibers, avoiding the shrinkage and elongation of its fibers. In a mixture of 35% with "dactón", it produces a resistant and wrinkle-free fabric.
  • In a mixture of 25% with "wool", the contraction and elongation of the resulting material is avoided, considerably improving its resistance.
  • It is more elastic than flax and hemp.
  • The resistance to torsion is also superior to that of flax and hemp.
  • It is the most incorruptible or resistant to chemical decomposition of textile fibers, which satisfactorily explains the preference given in China and India for the manufacture of ropes and threads for fishing.
  • It has the property of absorbing and quickly fixing colors better than cotton, linen and hemp fibers. they are more durable in Ramie than in other textile fibers.

CHEMICAL COMPOSITION

Laboratory analysis performed on the plant about 50 cm high, fresh, have yielded the following results; Expressing them in percentage of weight:

Water 82.6%
Proteins 4.3%
Crude fiber 2.4%
Calcium 0.7%
Fat 0.6%
Phosphorus 0.05%

For comparative terms, we are going to offer you the results obtained in a laboratory analysis carried out by the Autonomous University of Santo Domingo in May 1979 on a sample of mature ramie plants from Villa Mella, Santo Domingo:

Dry Matter (Air Dried) 24.5%
Crude protein 15.8%
Crude fat 4.5%
Crude fiber 29.7%
Non-nitrogenous elements 29.4%
Ashes 20.6%
Calcium 4.7%
Phosphorus 0.16%

THE FIBER

The fiber consists of pure cellulose, without the presence of "lignin".

Arthur Muller gave the following analysis between herb and ramie fibers in China:

% Chinese herb % ramie
Water 9.1 10.2
Aqueous extract 6.5 10.3
Grease and wax 0.2 0.6
Cellulose 78.0 66.2
Intercellular substance 6.2 12.7
ASH 2.9 5.6

COMPARISONS

The following table shows the physical properties of ramie fibers compared to other textile fibers: Ramie has been rated 100%

Property Ramie Hemp Linen Linen Cotton
Tension 100 36 25 13 12
Elasticity 100 75 66 400 100
Torsion 100 95 80 600 400

Ramie absorbs water faster than flax. It is very little affected by humidity. It has excellent absorbent characteristics.

USES

Ramie has multiple uses due to its varied characteristics.

The military sector has greatly benefited from its use, since they have taken advantage of it in the manufacture of hoses made in Germany, summer uniforms of the Chinese, Philippine, Japanese, South Korean and Swiss army.

The US Marines tested ramie fiber fabric and found it to be the strongest of all fabrics. The German army of Adolf Hitler used Ramie's cloth to cover artillery, for tents, for backpacks and for ammunition sacks.

In World War II all parachutes were Ramie structured; warships and merchant marine ships carried ramie as insulation in their propeller tubes. The military uses made of it are really very broad.

With the waste of its fibers, Alpha Cellulose is produced, used for the manufacture of pulp and paper; for air paper, London bank notes and bonds and for cigarette filters.

In India, the Philippines, China and Japan, fine guayaberas, shirts, suits of all kinds, dresses, blouses, shoes, gloves, ladies' handbags, bandages, gowns for doctors and nurses are made for their aseptic power, Stetson hats , indestructible and resistant rugs even to sea water.

From its leaves, which are 30% of the bush, a Ramie flour is made with 29% proteins that surpasses Alfalfa flour in everything; specifically in proteins, prices and amino acids, so essential for cattle, poultry and pig farming, whose animals have gained twice as fast in weight, as well as the eggs produced that are larger than normal, which has been proven by the Ramírez Valdez brothers in Santo Domingo on animals they own.

According to Mr. Francisco Tamas, member of the Academy of Sciences of the Dominican Republic, "pigs fed ramie never get sick; and their meat acquires an exquisite flavor as I could taste in the South of Mindanaos, where there is the largest pig farming based on ramie leaves ". He also tells us that, "it has also been proven - here in the Dominican Republic - that cattle fed ramie do not suffer from bloating or meteorism, as usually occurs with Alfalfa flour in the tropics".

The strongest, most biodynamic organic fertilizer that is known results from the stems of this plant; The pulp is also used to make gray cardboard.

It is also used in fabrics for oil, sails, transmission belts, coating and insulator 'of wires, tires. The yarn is used to make damask for furniture, upholstery, lace, embroidery and lace, fishing nets, in airplanes, for the manufacture of scarves, ties, velvets, plush and shawls.

In a work entitled "Ramie as an important element in the production of Meat and Eggs", Mr. Víctor Iván Ramirez Valdez, Dominican, says that "the development of livestock and the need to save land for other crops destined to to human consumption, they have made ramie a vital element in the production of meat and eggs.

In fact, small amounts of ramie included in concentrated feed guarantee animals excellent rations of proteins, vitamins and other nutritional factors essential for accelerated growth.

Foreign experiences and experiments carried out in our country have shown that cattle, pigs, sheep, goats and birds whose combined feeds have ramie as the main material, develop more rapidly than those fed with other concentrates, also proving their Antibiotic effects by eliminating almost 100% the occurrence of diseases. For example, investigations carried out by the author of this investigation show the following balance:

  • The mortality of calves and piglets whose mothers were fed ramie was lower by 20, than those that were fed with foods that did not contain ramie, being their growth and fattening faster.
  • No case of serious disease, including swine fever, was recorded in the experiments carried out, while other breeders were affected by this terrible disease, as well as by cholera, etc.
  • Ducks fed products containing ramie obtained greater weight than those that were fed with other edibles, for the same period of time.
  • Hens fed ramie prolonged laying time, in many cases reaching about 300 eggs per bird in one year, in addition to increasing their size. In some cases, these eggs had an extraordinary volume.

According to Carlos Remussi, ramie by-products may have more value than the fiber itself; It should not be forgotten that the fiber obtained (degummed) does not represent more than 1.2% of the harvested product (green stems with leaves).

According to Wills G. Waldo, dehydrated and ground ramie leaves supply greater amounts of carotene and protein than is commonly found in alfalfa flour. In addition, as the yield in green material is much higher than that of alfalfa, the annual protein yield is considerably higher.

Tests carried out show that ramie could very well supply a food rich in protein for human consumption. The leaf is a promising source of plant pigments, such as chlorophyll and xanthophyll.

Gummy substances contain wax and peptones that can be used for industrial or medicinal purposes.

The woody pieces of ramie are used as boiler fuels to provide the steam necessary to power the machines.

Fire pipes TYPES OF CLIMATES AND SOILS

Ramie requires medium and hot climates as happens in Boebmena tenacissima, B, although there are varieties that thrive very well in temperate climates such as boebmenia nivea, G.

The plant has developed very well from sea level to behind 1,600 meters, as in the Department of Antioquia, Colombia. Although it resists the safe ones, it needs humidity to obtain good harvests. This implies one of these two alternatives: locating the plantation in an area whose rainfall is high and well distributed throughout the year, greater than 1,800 mm, or, in another case, there must be some facility for irrigation. Withstands temperatures between 12 to 35 • C and atmospheric humidity of 65%.

The most recommended soils to establish a plantation of this are those fertile, deep, permeable, rich in organic matter, also loamy, clay loam, with drainage, little acidity, with a PH between 5.5 and 6.5, moisture availability enough.

MORE SUITABLE SOILS FOR RAMI PLANTING IN OUR COUNTRY

According to Dutch, Cuban and North American experts, the best land to grow ramie is the unused part of the forest, by CEAGANA at Hacienda Russia, in Santo Domingo.

Also including the Higüey - Chavón Yuma triangle, since there the rainfall is very favorable and the land is black with a deep vegetal layer.

In Villa Mella lands, Santo Domingo, it has prospered very well, which are distinguished by being soils with an average pH of 7.3, high in organic matter, more than 4%, medium in phosphors and low in potassium.

CULTURAL WORKS

GROUND PREPARATION

The land must be plowed deeply at about 20-25 cms., two harrow crosses are passed so that the land is well crushed, in order to be ready for sowing. It is necessary to give it 20 to 45 days after plowing, and then sow, since it is important that the weathering process occurs.

PLANTING

After furrowing, sowing should be done as soon as possible, preferably at the hours of less sunshine and when the soil is moist.

The rhizomes are manually distributed within the furrow, about 50cm apart. From the other, in fertile lands, and at about 30 cm, In medium fertility lands.

They are then covered with a 10 cm layer. Berra with a hoe or cultivator.

If the heat and humidity are favorable, sprouting will occur within 1 to 2 weeks.

In case of sprouting or germination failures, you must reestablish it in the third week, a good sprouting percentage is considered 80%, and a bad one, lower than 50%, Shovel sow one hectare, it takes 30,000 to 40,000 pieces of rhizomes, which corresponds to 30 bags.

WEEDING

It is essential to weed by hand with a hoe as many times as necessary before the first cut or harvest; likewise, between cutting and cutting it is necessary to weed, naturally if the weeds grow considerably, to eliminate the competition they make to the crop.

HARVEST

Ramie is normally harvested manually with a suitable tool - with a well-sharpened machete - although it has sometimes been harvested mechanically during the years 1945 and 1955 in Florida, which is more practical and economical in large plantations.

Stems are harvested when:

  • The plant stops growing, between two to two and a half meters in height
  • The lower half of the stems turn light brown.
  • The central part of the stem is hollow and easy to compress
  • The stem is almost completely fibrous
  • New shoots (shoots) appear on the surface of the soil

The content of usable fibers represents 3 to 5% of the weight of the green material and the total of the processed fibers (degummed) constitutes approximately half of two thirds of the weight of the dry strip depending on the quality.

The first harvest of ramie is generally produced 9 or 10 months after sowing and the cuts are made every 50 or 60 days.

However, it is common to make 3 to 4 cuts per year, producing an average of 22.5 tons per cut per hectare, that is, 67.5 tons per year in three cuts. An annual harvest can produce 1.7 to 2.0 tons of fibers without degumming. The fiber contains 25% or more of gums, waxes and other foreign materials resulting in a yield of 1.4 to 1.7 tons of clean fibers per hectare.

FIBER PROCESSING

In Panama and Brazil, the preparation of ramie fiber consists of two operations: shredding and drying, which are generally carried out in the field itself.

Washing the fibers with running water is not a normal practice in the conditions of Panama due to the difficulty of having water in the field itself, despite the importance of this operation to improve the quality of the fibers obtained.

The machine normally used for shredding in the field and the best known in Panama is the so-called "Periquito", composed of a 6 to 8 Hp motor that rotates a roll at 1,000 - 1,200 R.P.M. In this, an average of 6 to 8 operators are used, producing about 200 kg of medium-type fiber.

A second type of machine "La lquacu" uses 10 operations for its handling, obtaining an average daily yield of 600-800 Kg of fibers, but they are of lower quality because they leave a high content of residues impregnated in the fibers.

A third machine, "La Bandeirantes", employs 5 workers and produces export-type fibers. Its main drawback is its low performance since it operates 150Kg of fiber per day.

DESCORTIMMIMIENTO

Unlike most fibers, ramie fibers are not separated from the other components of the plant, but the latter is debarked. The simplest procedure is to break the stem by hand, removing the bark in its entirety with a round-tipped knife. The worker scrapes the surface to remove all internal and dry external films. Naturally, this method is done when labor is abundant, cheap, and the ramie is green.

There is a debarking called "Plant, whose field capacity is one hectare per day, which is appropriate for small producers in areas where costs are low, as in our country.

TIRE

One of the serious problems in ramie processing is degumming without strong weakening of the fibers, so it should be tackled as much as possible to bleach it.

Previously, the material is classified in grades according to its:

  • Rubber content
  • Pectin
  • Bark waste quality
  • Color
  • Smell
  • Length of the fibers before they are weighed and degraded.

After a preliminary softening, the fibers are degummed, boiling them in a dilute solution of bleach (caustic soda), sodium sulphite and sodium polyphosphate, the process of which is industrial in nature.

The degummed fibers are washed in soft water, bundled and air dried.

PERFORMANCE

In the experimental station in Louisiana, United States, in the second year the ramie produced 24,240 Kg / ha in cuts, resulting from that amount 21,653 Kg free of leaves or green part for the production of raw fibers that after debarking and degummed, it produced 242.35 kg of pure fiber.

CLASSIFICATION and MARKETING

Commercial fibers are classified according to their length in:

  • Top quality: those over 7.5 cm
  • Second quality: those between 7.5 and 5.1 cm
  • Third quality: those that are less than 5.0 cm.

In our country there are three companies that could buy ramie fibers produced in Dominican fields.

These companies are Fábrica de Sacos y Cordelería C x A (FASACO), Textil Los Minas y Sacos Nacionales, S.A., based in Santo Domingo, capital of the Dominican Republic.

MAIN PRODUCING COUNTRIES

The countries that grow the most are: China, the main producer, Japan, India, Formosa, the Philippines, Sumatra, the southern United States, Brazil, Colombia, Taiwan and Korea, and to a lesser extent: Cuba, Colombia and Mexico .

IMPORTING COUNTRIES

The countries that demand ramie fibers are: United States, England, France, Germany, Japan, Australia, Central America, Argentina, Colombia, Mexico and Italy.

RAMIE, AN ALTERNAINE

To lower costs, this crop turned into flour is a nutritious food that is used to feed birds, pigs, cattle, goats, sheep, horses and other animals, according to research from several countries

Ramie, a textile, forage and food plant, may be the answer to many years of searching for a low-cost nutritious food that is used for animal production and that meets the needs of economic benefits for livestock farmers who would produce meat, milk and eggs for the population at affordable prices.

This shrub, in addition to feeding animals, is used for the construction of houses in rural areas and the elaboration of cloth, thread, paper, fibers and cardboard for the manufacture of clothing, handicrafts, etc.

Ramie (Boehmeria nívea L. Gaud) comes from East Asia and produces the oldest textile fiber cultivated in China and Japan. The Egyptians already imported it from the East in the predynastic period (5,000 to 3,000 BC).

The high protein content of its leaves determined that researchers from tropical and subtropical countries (Guatemala, Brazil, southern United States) studied its forage aptitude, considering it a plant with high nutritional potential due to the production and quality of its forage. In different experiences with cattle, sheep, pigs, horses and birds, this species proved the feasibility of being used as a nutritional resource in the form of green forage and / or flour.

PESTS AND DISEASES

INSECTS

The pest that most attacks ramie and causes very serious damage is the leaf worm (Pilicordis ramentalis), the larva is green-whitish in color, reaching 10mm in length.

It feeds on the leaves and coils them when it becomes a nymph. Its intense attack leads to the complete defoliation of the plant and the cessation of its growth. This insect is efficiently controlled with 5% DD powder, at a rate of 12 Kg per hectare (1.6 pounds per hectare)

You can also use insecticides such as Azodrin, Malathion and others recommended to kill the insect. The dose will depend on those indicated by the manufacturer and the degree of attack of the insect.

There are other insects that attack this crop, but the degree of attack has been negligible and consequently they do not deserve any mention.

DISEASES

Although in our country the attacks of diseases have not been considerable, some that have deteriorated the plantation in other countries deserve to be listed.

In the United States, Rhizoctonia Solani, K, is a fungus that attacks newly transplanted young plants, sometimes reducing the plant population in such a way that it was necessary to reseed. This fungus can affect adult plantations, causing breakage of plants near or high above the ground. Causes spots on the lower leaves; Creospora Boehmeria has been found, attacking in nutrient-deficient fields, in the summer months and late spring.

In Japan and South Vietnam, the white fungus has caused heavy losses to ramie growers on several occasions. Its mode of attack is characterized because the affectation is located below the surface of the earth in the stems of the plant, manifesting the symptoms late; a wilting of the plant is observed, the leaves turning yellow. Some control of this fungus has been achieved by soaking the plants immediately before sowing them for 3 hours in a 1: 1000 solution of mercury chloride.

RAMI EASY TO PRODUCE

This plant is produced by rhizomes, cuttings and / or seeds. propagation by seeds is not the most convenient, because small seedlings show slow growth from implantation to the first cut (100 to 120 days), but by rhizomes, on the other hand, the growth time from implantation to first cut is significantly minor (70 to 90 days).

The rhizomes to be used should be cut into pieces 10-15 cm long, placed in grooves 10-12 cm deep and covered appropriately.

The sowing distance ranges between 0.60 and 1.20 m between rows, and 0.30 to 0.60 m between plants. Ramie is a plant with a herbaceous, perennial, rhizomatous texture; its stems vary between 1.00 and 2.50 m in height, its leaves are large, heart-shaped and velvety; Its tiny yellowish flowers are arranged in panicles in the axils of the leaves; Its oval shaped fruits are small and very numerous.

Ramie, like most fiber crops, requires slightly acidic, deep, well permeable soils with a good content of organic matter. Their water needs are important, because they require high levels of precipitation (around 1000 mm) or the aid of complementary risk.

Atmospheric dryness and hot, drying winds limit the production of green matter in this species.

It has two implantation seasons: autumn and early spring. It is advisable to do it in autumn so that the plant takes root well before winter and emerges strongly in the spring.

The ramie cycle is spring summer autumn. Every 2 to 3 years it is important to reinforce the fertility of the soil by applying nitrogen, potassium and calcium. After each forage cut or during prolonged dry periods, watering should be done. Good weed control is necessary during the early stage of crop development, until the plants produce enough shading to eliminate them on their own.


FORAGE QUALITY

In Tucumán, this crop was worked in the Experimental Field "El Manantial", of the Faculty of Agronomy and Zootechnics of the UN, during the 1996 to 1998 campaigns. The area presents a temperate subhumid to humid climate with a dry season, regime monsoon, mean annual rainfall of 950 mm and mean annual temperature of 19.7 ° C. The investigations carried out contemplated cuts for forage, every 45, 60 and 75 days, during the crop cycle.

In each of them the yield per hectare was analyzed, in the following components: whole plant, stem and leaf. The results obtained indicate that the total values ​​of green matter / ha ranged between 96 tn / ha for the cutting frequency every 45 days, and 121 tn / ha. For every 75 days. Regarding dry matter / ha, the highest percentage was obtained in the cuttings every 75 days: 23.9% whole plant, 22.81 stem and 25.3% for leaves. However, it should be noted that the harvests every 45 days delivered the material with the best nutritional quality and digestibility.

At this stage, the stems are less fibrous and are used better. As for the study by components, the leaves are the best source for feeding animals.


THE KEYS

  1. Ramie for birds

    As it has been proven in experiments carried out in different countries that ramie contains 28 ° of protein, why is it not being used in the country as part of the corn and soybeans that are imported to feed poultry and pigs? Victor Ramirez wonders.

  2. Tested

    Here it is proven that ramie cultivation grows well, even with more foliage than in other countries. In addition, it is an easy shrub to grow and easy to handle.

  3. Alternative

    As ramie can be an alternative to produce meat, it should be used, according to Ramírez.

  4. Resistant to pests

    Ramie is a crop that showed great resistance to diseases and pests during years of evaluation, say researchers who consider that due to the adaptation evidenced in some areas and its productive qualities it can be an alternative to take into account for animal production.

  5. Satisfied ranchers

    In livestock farms in Guatemala, ramie has been tested in the form of flour, from plants of 0.50 cm in height, determining that the addition of 5% of this flour in balanced feed mixes for birds provides enough amounts of vitamin A and riboflavin.

STUDIES CONDUCTED


We consider ramie as a solution or the “Mad Cow” disease
WHY DOES TROPICAL LIVESTOCK FARM NEED RAMIE FLOUR?

It is known that most of the peoples of the world in Asia, Africa, Central America, South and the Caribbean are starved for protein. In fact, protein and fat are the two most scarce food species in the world economy.

Countless studies by international organizations in America have proven, as can be seen, the comparative state below that ramie produces 5 times more protein per acre than soybeans, which is enough to prove its economic value.

In terms of nutritional value, Ramie is the most outstanding tropical feed. In addition, Ramie as a forage is a semi-concentrate and mixing it with other feeds increases the digestibility coefficient with 1,000 percent.

Ramie flour contains in a stabilized form. vitamins, proteins, minerals in a ration well balanced by nature.

Ramie-fed animals are healthy, fat and never suffer from contagious diseases. Ramie acts in animals as a preventive medicine.

In the tropics it is of great importance that while Alfalfa produces gases in animals with serious consequences, ramie is free of this defect.

Apart from chemical analysis, ramie demonstrates biological quality and produces biological activity. It contains enzymes that are the most important and powerful agents of all metabolism. It's also good to say that ramie contains a lot of vital amino acids like Tryptofane, Lycin, and Methionine.

Experience has also shown that calves are born with greater resistance power when cows are fed Ramie flour and even birth is easier and smoother.

Bulls that receive Ramie flour produce with more vitality and procreate more frequently and the same can be said of male pigs.


RAMI AS A SUBSTITUTE FOR SUGAR CANE
What stages has been reached in the Dominican Republic regarding the research process and experiments developed with ramie?
  • We have processed ramie fiber making tablecloths, hammocks, cloths, dolls, among others.
  • Animal feed has been produced in general (feed, forage and flour).
  • We have obtained Sirop.
  • Food intended for human consumption has been produced.
  • We have prepared nutritious food by mixing it with another plant, for malnourished children and malnourished pregnant mothers.
    All these investigations and their analyzes have been carried out in prestigious institutions such as INDOTEC, JAD, Veterinary Laboratory, YSDA, among others.
  • Paper has also been produced.

RESULTS

What have been the results of these experiments and investigations?
  • When it comes to fibers, we have handcrafted examples to demonstrate them.
  • As animal feed, we have evidence in animals.
  • When it comes to human food, I (Víctor Ramirez) am an example.
  • When it comes to papermaking, we have evidence.

PROCESS
Who has cooperated in these ramie processes in the Dominican Republic?

There are institutions such as those mentioned above, which have contributed to the analysis and verification of the characteristics and agro-industrial properties of this important alternative in different aspects.

The honorable former President of the Republic, Hipólito Mejía, also contributed, as Secretary of State for Agriculture, 1978-1582.

Others of equal mention are the engineer Heriberto de Castro, Claudio Caamaño, graduate Margarita Peralta, agronomist Nelson Rodriguez, Barbarin Magallanes, Pedro Duran, agronomist José Delgadillo, engineer Cesar Sandino de Jesus, Marcos Collado, my relatives and wife Kenia Tejeda with her moral and spiritual support manifesting in all my circumstances with the ramie.


BENEFICIARIES
Who has been favored with the work of VIR for more than 35 years?

Many institutions, associations and foundations selflessly facilitating ramie rhizomes, despite the economic value that would also represent to me companies that have taken advantage of people's knowledge and experiences for their own benefit by pretending to be altruistic.

Currently, there are experimental fields: two in La Vega and one in Santo Domingo, from VIR, S.A. It is definitely feasible or profitable to carry out a Ramie agro-industrial project in the Dominican Republic.

We refer to studies and analysts that we have, through which its feasibility is verified.


IT WOULD LOWER COSTS
Would it lower the cost of different products, if they are processed with ramie?

True, both in health, in nutritious food for humans and animals, and by the way, in the economic aspect.

Mrs. Persia Alvarez, in a conference: "International Implementation of Practices for Food Safety", given at INDOTEC, made reference to different diseases from food which can be eradicated with good agricultural practices.


DISEASES
Could ramie prevent diseases in animals that serve as food for humans?

We will give an example of research and experiments, namely:

Foreign experience and experiments carried out in our country have shown that cattle, pigs, goats and birds whose combined food has ramie as the main material. They develop more quickly than those fed with other concentrates, and their antibiotic effects are also proven by eliminating almost 100% the occurrence of diseases.

No case of serious disease, including swine fever, was recorded in the experiments carried out, while other breeders were affected by this terrible disease, as well as cholera and others. Ramie-fed animals are healthy, fat and never suffer from contagious diseases.

Ramie acts in animals as a preventive medicine, it is antiseptic.

Professor Voisin visualizes that the shortage of microelements and the enzymes that these elements support, cause irregularities in cell growth and metabolism, resulting in cancer and other diseases.

Fortunately, ramie contains all the microelements and enzymes mixed by nature itself to produce a healthy metabolism and avoid dangerous irregularities in cell formations.

Meat, egg and milk producers can lower production costs and at the same time increase the nutritional value of the food portions they supply to their animals, if they manage to integrate ramie into the daily diet.

Ramie is an excellent natural product with exceptional characteristics, including having in mind the essential nutritional elements for the animal body.


FLAVOR

We have observed that ramie is tasteful, rich in carotene (Vitamin A), fat, non-nitrogenous elements such as calcium and crude fiber.


FOOD

This forage plant can be the answer to many years of searching for a very low-cost nutritious food that is used for animal production, and in turn, that meets the needs of economic benefits for the farmer, as well as the supply of meat, milk and eggs for the population.

Today the possibility of introducing ramie-based food forms is presented.

Ramie can be used fresh, dry (in the form of flour in pieces), as well as ensiled with other materials.


INDUSTRIALIZATION

As we can see, ramie can serve as the basis for the take-off of an industry capable of revolutionizing animal nutrition in our country, from the nutritional contribution to the reduction of costs.
