Artificial High-yield Cultivation Techniques of Wild Osmunda

Osmunda, the scientific name "purple", commonly known as "large nest dishes", "wild peas", "broom dishes", "pheasant head" and so on. Is a fern Asteraceae Aster is a perennial herb. It is generally wild, with edible stems and leaves for food. Its nutrient-rich, delicious taste, 80g water content per 100g of fresh stems and leaves, protein 3.8g, fat 0.5g, carbohydrate 9g, calcium 270mg, phosphorus 70mg and other compounds. With blood circulation, stomach, detoxification, lower blood pressure, anti-cancer anti-cancer health effects. Its stems and leaves not only can be eaten fresh, but also can be processed into dried Osmunda, exported to Japan, Southeast Asia and other countries and regions, is internationally known as "Chinese dried red cabbage," has a very high food value and commodity value.
Osmunda mainly distributed in the humid mountainous slopes or gutters of two high mountains and high mountains at an altitude of 500-1500m. In order to make full use of this resource advantage to meet the market demand and expand the income channels of the people in the mountainous area, the author started the artificial single-cultivation experiment of wild Osmunda in 1996 to explore its high-yield cultivation. Technology has now been successful. It not only has high output, but also has good quality and high efficiency. More than 700 kg of fresh stems are harvested per 667m2, and more than 100 kg of finished products can be made. The net income of 667m2 is more than 5,000 yuan. The success of this experiment has broken through the traditional theory in the history of Osmunda cultivation. Traditionally, Osmunda can only be interplanted with other economic forests or crops, or artificial shade plants are used to simulate the wild environment for shade cultivation and cannot be singled. Cultivation. The author believes that the light requirement is "not strict". On the basis of traditional cultivation, it is entirely possible to carry out single cultivation. On this basis, the author conducted a single-cultivation experiment for 5 years, affirmed this theory, and explored a set of high-yielding cultivation techniques. It is summarized as follows.
First, the preparation stage before cultivation
1, the choice of cultivation. The cultivation site requires the selection of a damp field in the soil, with the most suitable for shady slopes or semi-yin and semi-yang areas. The soil is required to be acidic, with a pH of 5.5-6.7, and alkalinity is avoided. Texture can be in the soil, medium-coarse soil or sandy soil can be.
2, fine for scorpion, re-basal fertilizer. Before transplanting, the cultivation site shall be deep-turned to a depth of 30cm. The soil shall be finely crushed, loose, free of gravel, and free of weeds. For 畦 width 120-150cm, groove width 25--30cm, 畦 surface to be flat; for every 667m2 combined with deep-ripening organic fertilizer applied 2000-3000kg as the base fertilizer, base fertilizer cover fine soil 10-15cm, to be planted .
Second, the transplanting stage
1, timely mining, timely transplanting. Wild Osmunda can be transplanted throughout the year to survive, but practice has shown that it is best to excavate at the end of October-early December. Excavation will affect the accumulation of nutrients too early, affect its differentiation and unfavorable operation too late, and will easily freeze to death. The excavation and seedling shall be timely transplanted to prevent sun exposure and wind and rain.
2, fine digging seedlings, deep planting close planting. Osmunda does not have radicles, does not form a true root system, and only adventitious roots are born on rhizomes. The adventitious root system is more developed. The 2-3 year old root system can reach 30cm square. When picking and digging, strong strains should be selected to reduce and avoid artificial damage to roots and growth cones. The last 4 lines should be cultivated with 15-20cm spacing and 30-- 40cm, the transplant depth is 10-12cm. When transplanting, it is not appropriate to give birth again. It is recommended that transplanting with soil be carried out. Roots should be laid flat. The filling should be compacted and compacted. The surface layer should cover about 5 cm of fine soil, and it is required to cover the stem growth cone. Finally, cover with straw or other straw, pouring enough water.
Third, the middle and late management stage
1. Weeding and weeding, and cultivating earthworms. In the entire growth period of Osmunda, field weeds should be controlled. Each year, sprouting and germination occur once every 15-20 days for an cultivator and weeding. The cultivator has a depth of about 5cm. Combined with fertilization, it generally uses 200-300kg of excrement per 667m2. In addition, the leaves of Osmunda oleracea have the characteristics of growing upward from the lower part of the growth cone, gradually revealing the growth cone and part of the root system. Therefore, it is necessary to cultivate the rammed soil once a year after the garden is harvested to cultivate strong seedlings and promote early-onset trees.
2, scientific management, rational fertilization. Weixing grows in a humid and humid environment, especially in the spring and summer growing season. The soil should be kept moist and the relative soil temperature should not be lower than 80%. In autumn and winter, the standard can be lowered appropriately, but avoid drought. During the harvest period of March, April and May, 100--200kg/667m2 of human excreta was applied once a week and applied with 0.5% potassium dihydrogen phosphate solution. In the future, every three years, a farm fertilizer should be used as a base fertilizer to prevent aging and degradation.
3, timely cutting leaves, timely garden. When all the stems and leaves fall, they should be cut off about 1.6cm from the ground in time, and weeds should be collected timely in the pastoral and surrounding areas. Finally, weeds should be used to supplement the potash in the soil, and it is also beneficial to keep warm for the winter.
4, fewer pests, integrated control. During the whole growing season of Osmunda, the diseases and insect pests are very few. According to many years of observation, only some unfavorable environmental factors, such as moisture and fertilizer, have caused no insect pests.
Fourth, picking notes
1, scientific harvest, planting and breeding. The second year after transplanting should not be harvested or harvested in small amounts, and it is not until the third year that the “high yield shelf” can be established to enter the high yield period. Stopping the harvest time is generally controlled on or after May 1st 5 days.
Specific criteria should be based on local microclimate, to retain each plant has 4-6 leaves for photosynthesis, to maintain their own growth balance is appropriate. To achieve the purpose of planting and breeding.
2, timely cutting, improve quality. When the stems and leaves are about 10-15cm high, when the new leaves are not curled, they should be cut every morning; when shearing, the fruit should be cut with scissors to prevent other tender stems and growth points. Postharvest processing according to the purpose of use.
