The effect of bracken
1, eat. The bracken is wild in the forest, mountain and pine forests. It is a green wild vegetable without pollution. The bracken is rich in vitamins needed by the human body. It has the functions of strengthening the stomach and clearing the intestines and relaxing the muscles. Before eating the bracken, immerse it in boiling water, then immerse it in clean water to remove the odor. The treated bracken has a smooth, fragrant taste when served, and it is a rare, refreshing appetite if added with appropriate ingredients. Bracken can also be fried, and can be processed into bracken, made into stuffing, pickled into canned food, etc. Bracken root contains a kind of high-grade starch. In addition to general medicinal or fried food, it can be made into fern powder by grinding and filtering. It can be used to make maltose, biscuit, noodles, jelly and other foods instead of soy flour or glutinous rice. It can also be used for wine making and extraction. alcohol. Bracken can be used to make sugar, biscuits, powders and pharmaceutical additives.
2. Medicinal. Modern research suggests that cellulose in bracken can promote intestinal peristalsis and reduce the absorption of fat in the stomach. Bracken is cold and sweet. It has the effects of clearing heat, removing phlegm, detoxifying and moistening the intestines. Regular consumption can reduce high blood pressure and relieve symptoms such as insomnia and dizziness. Bracken also has the effect of diuresis and diarrhea. The dietary fiber contained in bracken can promote gastrointestinal motility, and has the functions of laxative, clearing and detoxification. Bracken can also help treat dysentery, hemoptysis and rheumatism. Arthritis and other diseases. Long-term consumption has a preventive effect on high blood pressure, dizziness, uterine bleeding, arthritis, measles and influenza. Brackenin has a certain inhibitory effect on bacteria and other microorganisms, and can be used for fever, intestinal wind, heat toxicity, eczema, sore and other diseases, and has good bactericidal, clearing, heat-clearing and detoxifying effects. Lower gas pressure. Some chemical components contained in bracken can dilate blood vessels and lower blood pressure; crude fiber can promote gastrointestinal motility and has a laxative effect. Bracken can clear the intestines and detoxify. Folk commonly used bracken to treat diarrhea and dysentery and urinary dysfunction, has a certain effect. Bracken can be made into powdered skin, powdered for generations of food to satisfy hunger, has spleen and qi, strengthens the body and enhances disease resistance.
Artificial cultivation techniques of bracken
1. Breeding of good breeds:
According to the color of the fern stem, the fern can be divided into three lines: red stem, middle, and green stem. The green stem fern has good quality and is the best strain. Different species of Brackens can be selected from wild communities, and their rhizomes can be excavated and transplanted in the planned fields for evaluation of resistance, growth, yield, quality and other indicators, and then select excellent strains. Spores are used for plant propagation.
2. Cultivation of root strains:
The selected strains of spore-producing plants are used to cultivate roots, and wild rhizomes can also be collected to cultivate roots. During the collection period, it is advisable to use the low temperature period from the early winter when the stems and leaves are withered to before and after the beginning of April. Try to dig deep to prevent root breakage and plant as soon as possible to avoid excessive water loss. If you are waiting for spring planting, you must first plant it in the soil. Before planting the roots, it is necessary to comprehensively deep-plow the soil early, and apply organic fertilizer such as compost. The ridge width of the whole land is 60-80 cm, planted in a single row, planting depth of 10 cm, and the soil is covered after the righting. This kind of planting 100 square meters requires 8 to 10 kilograms of fern roots. The planting period of roots is from late October to mid-April, and it is necessary to cover the grass to prevent drought after planting. It takes at least one year to cultivate.
3. Cultivation and harvesting of bracken:
The choice of woodland. Although the requirements for soil in bracken are not strict, in order to produce bracken with good quality and high yield, it is best to choose a gentle slope with a slope of 120°-180° and a depth of 40-50 cm. Afforestation of young forest land or forest gaps, alluvial slopes. The soil is acidic and slightly acidic.
Site preparation and fertilization. To prepare the land before transplanting in the spring of the second year, it is to carry out deep ploughing in the autumn before transplanting, and to fine the clods. At the same time, organic fertilizer is applied, and the decomposed pig and horse manure are used as the base fertilizer. 500 to 1000 kg per 667 square meters (1 mu), 25 to 30 cm deep, and soil disinfection.
Cultivation of bracken. In the early spring, root the fern that has been cultivated for 1 year, choose a strong cut into 20~30 cm roots, pay attention to protect the bud tip on the stem, do not hurt, and avoid sun exposure. Do not ridge or do squatting, open a ditch 10-15 cm deep every 20 to 22 cm, place the seed in the ditch, cover 5 cm or 8 cm thick soil, pour enough water, then cover about 3 cm thick Dry leaves or straw, etc., used to prevent drought and moisturizing. Generally, 100 to 130 kilograms of roots need to be transplanted per 667 square meters. After planting, it is necessary to carry out topdressing and irrigation to promote the vigorous growth of bracken.
Field management. Water spray starts at the beginning of April every year to promote early sprouting. Always keep the soil moist, especially in areas prone to spring drought. After the summer fern spores are scattered, the soil should be kept moist to facilitate spore germination. The grass that was laid in the year was rotted, and the next spring was to be layered again. Light is an important factor in the growth and development of bracken. The light is too strong, the cell stretch is blocked, the petiole is short, and the edible value is low; when the light is weak, the petiole is light green, the photosynthesis is poor, the photosynthetic product is insufficiently accumulated, and the quality is poor. Therefore, in the field management, according to changes in sunshine, weather, and sunny weather, adjust the light intensity with a shade net.
Harvest of bracken. The harvesting began in the second year of cultivation. The harvesting period was from late May to early June. The vegetables began to sprout in a large number of times. The fern was harvested to a length of 10 cm or more and harvested three times a week. After entering the winter, the dried shoots of the fern are set on fire and then covered with hay. At this time, the underground rhizome of bracken has been criss-crossed, and the fern that sprouted in the next year is strong and tidy.
