Bracken, also known as the dragon dish, fern vegetables, boxing, etc., is a perennial herb. The bracken has the characteristics of delicate taste, peculiar flavor, etc. It has always been known as Lin Hai Shan Zhen. It contains more than 16 kinds of amino acids and 7 kinds of essential trace elements and 5 kinds of constant elements. It has the functions of dehumidification, antipyretic diuresis, rheumatism, urination, cough, and rectal prolapse. It is one of the wild vegetables popular among people at home and abroad. The cultivation techniques are introduced as follows: (1) Open cultivation 1, breeding methods. (1) Spore sexual reproduction. During the spore maturation period of July-August, the spore group with the appearance of brown uncracked was selected, and the spore-bearing leaves were placed in a clean and smooth paper bag to air dry for later use. Take rotted weak acid garden soil plus river sand turf soil mix and sifted, sterilized with steam for 30 minutes, soil moisture is about 95%. The spores were sowed in the above culture soil, do not need to cover the soil, to be shaded, keep the temperature at 20-25 °C, 35-40 days after the spores formed pale green spoon-shaped or fan-shaped original leaf, keeping light for 4 hours per day . When it grows to a height of 5 mm, it sprays water twice a day for a week to develop into sporophyte plantlets. When the leaves grow to 5 mm and the third leaves grow, they are transplanted. At this time, the soil must be kept moist and shaded. The second year begins to thrive. Planting can grow for 10 years, from May to June each year, when the plant height is 25 centimeters, young leaves can be harvested, and 2 to 3 can be harvested continuously. (2) Methods for propagation of rhizomes: Take root rhizomes from wild fern fields in early spring or late autumn and put them in plastic bags to prevent water evaporation. In the spring of the year (late April - early May) and autumn (late October), transplanting can be carried out. When transplanting, the rhizome is divided into several sections, each section maintains 1-2 buds and maintains a certain amount of fibrous roots. 2, the election site preparation. Choose a gentle slope with a slope of 12-18 degrees and a depth of 40-50 cm. Abandoned grasslands, young forests or gaps in forests, alluvial slopes. The soil is neutral and weakly acidic. Deep plowing in autumn, soil preparation in the spring before transplanting in the second year, applying organic manure, decomposing manure and fertilizer as base fertilizer, 4000-5000 kg per mu, turning 20 cm deep, ridge or rake, and soil disinfection . 3, transplanting. Open ten to fifteen centimeters deep ditch on the raft or ridge surface, plant the seedlings or sub-roots of the plant with 5-10 centimeters in the ditch, cover the roots with 5-8 centimeters, and cover 3 centimeters thick on the ridges or rafts. The branches and leaves or straw, the soil moisture remained above 60%. Before the winter, the dried stems and leaves of the fern were burned with fire and covered with hay to prevent winters. 4, picking and processing. The harvest can be harvested in May of the following year. It is harvested until July. The picking time must be based on the petiole old tender, not too early or too late. After picking, topdressing and watering should be performed in time to promote robust growth. The standard for harvesting of export products is generally 22 cm in length. Immediately after harvest, put hot water into boiling water, and remove and dry it into small bundles to market. (B) Protected cultivation 1, scaffolding and soil preparation. According to local conditions, simple sheds of bamboo or steel structures are selected for production, and their location should be located at a flat place at a higher level of sheltering from the wind. The soil is required to be neutral or slightly acidic, the soil is loose and fertile, the water conservation and fertility are strong, and the groundwater level is low. For the convenience of picking, the width is generally 1 - 1.5 meters, Mushi rotted farmyard fertilizer 2000-3000 kg. 2, timely planting. In a well-made trampoline, dig a 12 cm deep trench every 20 cm, plant the seedlings planted in the furrow at a planting distance of 5 cm or place a rhizome with a root, cover the soil 5-10 cm, and cover On straw or other stalks, sprinkle an appropriate amount of water, and then cover with a shed or cover the mulch. 3, fertilizer and water management. Bracken grows in a humid and moist environment, so after planting, the soil is always kept moist. Often use watering water spray, but not water, in case of rain, we must open the ditch in time for drainage. After the first batch of sprouts are unearthed, the quick-acting fertilizer (human excrement or potassium dihydrogen phosphate) shall be promptly chased, and the fertilizer will be top-dressed each time a batch is picked. After planting, cover the membrane in time to promote sprouting. The germination period requires that the ground temperature be above 15°C, the temperature should be above 20°C, and the growth should be accelerated after budding. The required temperature should reach 25°C; it should be covered all day within one week after transplanting, and be properly ventilated during the day; when the temperature exceeds 30°C The shed's skirt film can be lifted and covered with shade nets and straw curtains for cooling. 4, picking. The use of double-cover mulch cultivation, can be listed one month earlier, the earliest can be listed during the early spring festival in February, when the seedling height of 30 cm or so, the new leaf curling can not be harvested, 2-3 days 1 time.
