Medium maturity cowpea variety outdoor spring sowing planting method

Abstract

The invention discloses a planting method for spring sowing of mid-ripening cowpea varieties in the open field, which comprises soil disinfection, fertilization for site preparation, ridge farming, plastic film covering, seed treatment, seedling cultivation in nutrient pots, transplanting seedlings at the right time, seedling transplanting methods, reasonable and thin planting, and post-transplanting Surround the cowpea field with nylon nets and remove the nylon nets after the seedlings are established. The seed treatment of the present invention shortens the germination time of seeds, improves the germination rate, and ensures that all seedlings are sown at one time; ridge cultivation can adjust water, heat, and air conditions, reduce waterlogging damage, and reduce pests and diseases; plastic film mulching can improve drought resistance, moisture conservation, rain prevention, and drainage effects , and save the cost of weeding; transplant seedlings properly, avoid the low temperature in spring, improve the robustness of cowpea seedlings, and increase the yield of cowpea; isolation with nylon nets prevents bird damage and small animals from eating cowpea seedlings, and saves the cost of supplementing seedlings. The present invention is suitable as a planting method for spring sowing cowpea in the middle and lower reaches of the Yangtze River, and is readily accepted by bases, planters or scientific research units, and has excellent prospects for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a spring sowing planting method of a mid-ripening cowpea variety in the open field. Background technique [0002] Cowpea is an annual herb with high economic value. Its bean sprouts, seedlings, and tender pods can be used as vegetables. The grains have high protein content, especially rich in lysine and tryptophan, and can also be used as staple food. Cowpea plays an important role in the annual supply of vegetables, especially in the "off-season" supply of vegetables from July to September. In recent years, the quality and yield of cowpea have been greatly improved due to the continuous promotion of new varieties of high-quality cowpea, and the wide application of technologies such as seedling cultivation and transplanting, mulching, and greenhouses (Rao Libing et al., 2008; Liu Lieping, 2011). [0003] The planting method of cowpea is directly related to t...
