Nowadays, the market prospects of wild vegetables are getting better and better. More and more people are pursuing healthy vegetables. Therefore, many farmers’ friends have seized this opportunity to start planting wild vegetables on a large scale. Today, Huinong.com has a small series to talk to you about wild. Artificial cultivation techniques of Osmunda.
1 Preparation before cultivation
Wild Osmunda must be fully prepared before artificial cultivation, especially in terms of seedling, land selection, land preparation, fertilization and ridges. Seedling technology requirements are relatively high, professional, and do not blindly operate, must be carried out under the guidance of professional and technical personnel. According to the characteristics of the large number of spores, the seedlings of Osmunda chinensis should be selected for sexual reproduction, and effective measures should be taken to control the environment and promote the growth of roots, stems and leaves. Through the two-stage seedling technology of Osmunda sp., the seedling time is shortened, the seedling cost is reduced, and the seedling rate is further improved. Wild Osmunda is spawned, paying attention to protecting the buds and intact roots. Generally, the upper part of the seedlings of Osmunda chinensis was basically dead until the spring of the next year. In this process, we must pay attention to the wild Wei Cai, after the excavation, do not expose to the sun, pay attention to moisturizing, shading. The growth of Osmunda needs an acidic environment. Therefore, it is necessary to select acidic soil with high organic matter content. The selected waste slope is best to retain water and fertilizer, and the water source conditions of the cultivation site are better. Before the plant is planted, the vermilion is finely prepared to remove weeds and shrubs. It is not advisable to cultivate more than 20 plants in the field of 667m2, otherwise it will have an adverse effect on the growth and development of Osmunda. Choose decomposed organic fertilizer, and immediately apply ridge after the base fertilizer is applied.
2 transplanting
Choose to transplant from mid-October to mid-March of each year, timely excavate in neutral or slightly acidic soil, timely transplant to prevent sun exposure and wind and rain, avoid mining prematurely affecting its nutrient accumulation, and ensure The survival rate of transplanting is improved. If the time is too late, it is easy to freeze to death and unfavorable differentiation. Generally, the artificial stem cultivation adopts the rhizome transplanting method. The method has good planting uniformity, is put into production early, is easy to grasp, and has high yield. On a sunny day, the ground is burnt and burnt, and the shallow control is 5-6 cm, and the farmer's fertilizer is applied. When transplanting, it is necessary to use the hands to compact the Weicai around with fine soil. According to the width and flatness of the sorghum, the roots of the wild vegetables are burrowed according to the specifications of the plant spacing of 40cm. Immediately after planting, water should be poured to improve the survival rate. The farmyard manure must be fully decomposed by stacking, so as to avoid the high temperature at the time of fermentation leading to rooting. Finely dig the seedlings and make a reasonable planting. The results of many years of experiments have shown that if the density is too dense, the input will be increased, and the later results will be poor. There is no radicle in Osmunda chinensis, and the root system is more developed. The strong strain should be selected during mining to minimize the damage to the root system. It is recommended to transplant soil with soil. It is not advisable to divide the soil when transplanting. The filling should be compacted and compacted. Finally, the straw is covered and the water is poured.
3 middle and late management
After the artificial cultivation, the wild Osmunda must not neglect the management in the middle and late stages, timely weeding, topdressing and irrigation. During the whole growth period, Osmunda has to control weeds in the field, cultivating and weeding, and cultivating the soil. Before germination and germination every year, we will carry out cultivating and weeding. At the same time, combined with fertilization, Weicai gradually exposes the characteristics of growth cones. Pay attention to scientific management. According to the characteristics of Weiwei's favorite moist environment, some corn can be planted around the cultivation pot to make shades and achieve the effect of shading. Attention should be paid to keeping the soil moist. During the harvest period, it is necessary to cooperate with the application of human excrement and potassium dihydrogen phosphate solution once a week to effectively control the aging and degradation. The main reason is to apply in the rainy days or after the rain. . The soil should be kept moist after planting, and the field drainage should be done in a rainy season. Careful and meticulous collection of weeds in the pastoral and surrounding areas, the disease and insect pests during the whole growth period of Weicai are relatively small, but comprehensive prevention and control is still required.
4 harvesting
Transplanted Osmunda is generally not suitable for harvesting in the same year, and it is best to harvest it in the second year. The artificial cultivation of wild Osmunda must be scientifically harvested, combined with the actual cultivation, and set up a “high-yield shelf†to enter the high-yield period. It is harvested once in the second year and twice in the third year. The stop harvesting time is generally controlled 5 days before and after May 1. When the petiole is unearthed for about 20cm, it can be harvested, and the fibrosis of the leaf base should not be harvested, otherwise the value of the commodity will be reduced. According to the microclimate of each region, keep 5 leaves per plant, maintain its own growth Balance, and achieve the purpose of combining species and raising. Be careful when harvesting. Do not damage the roots of the sauerkraut and protect the roots so that they can continue to sprout. When the new leaves are curled, they should be cut in time, and cut every morning to improve the quality of the vegetables. After the harvest, the vermilion should be processed immediately, washed, boiled in boiling water, and taken out to dry.
The artificial cultivation technique of wild Osmunda is said today, please ask the farmers who need it to study hard.
