Medium maturity cowpea variety outdoor spring sowing planting method

Abstract

The invention discloses a medium maturity cowpea variety outdoor spring sowing planting method. The method comprises oil disinfection, land preparation and fertilization, ridge planting, plastic film mulching, seed treatment, nutritive bowl seedling growing, timely seedling transplanting, seedling transplanting, reasonable thin planting, enclosure of the periphery and top of a cowpea field with a nylon net after seedling transplanting, and removal of the nylon net after final singling. Through the seed treatment, the seed germination time is shortened, the germination rate is increased, and all seedlings are planted at a time; ridge cultivation is adopted, so that water, heat and gas conditions are adjusted, waterlogging damage is relieved, and pest and disease damage is reduced; a mulching film is used for covering, so that the drought combating, the rain resistant and flood drainage effects are improved, and the weeding cost is reduced; the seedlings are transplanted properly, so that a low temperature in spring is avoided, the robust degree of the young cowpea seedlings is increased, and the cowpea yield is increased; the nylon net is adopted for isolating, so that bird damage and eating of the cowpea seedlings by small animals are avoided, and the cost on filling the gaps with seedlings is reduced. The method is suitable for spring sowing cowpea planting at the middle and lower reaches of the Yangtze River, is easily accepted by bases or growers or research institutions and development institutions, and has great popularization and application prospects.

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...
