Abstract

The invention provides a planting method for crop rotation of cowpeas and paddies. Spring sowing cowpeas and summer seeding paddies are planted in a crop rotation mode, crop rotation is conducted once every year, moreover, fertilizer is applied rationally in the planting period of the cowpeas, and no fertilizer is applied in the planting period of the paddies. The method of rational application of fertilizer comprises the following steps that first, soil is prepared before the cowpeas are planted or cultivated, and 50 kg of calcium superphosphate or calcium magnesium phosphate is applied per 667 m<2> before the soil is prepared the last time; second, 4 kg of compound fertilizer is applied in furrows per 667 m<2> to be used as seed fertilizer after planting or cultivating is completed, and then earthing up and tamping are carried out; third, 30 kg of compound fertilizer is applied per 667 m<2> by combining intertillage weeding with earthing up after cold-proof cultivation and film uncovering of a small shed are completed; fourth, 30-50 kg of compound fertilizer is applied per 667 m<2> when the cowpeas bloom and bear pods by 9-11 cm; afterwards, 30 kg of compound fertilizer is applied per 667 m<2> every other 10 days till the cowpeas are harvested, and the field for planting or cultivating the cowpeas is used as the local field for planting the paddies. By the adoption of the method, no fertilizer needs to be applied in the cultivating process of the paddies, economic benefits, social benefits and ecological benefits are huge, and the income can be increased obviously.

Description

technical field [0001] The invention relates to the field of agricultural technology. More specifically, the present invention relates to a planting method of cowpea and rice rotation. Background technique [0002] Crop rotation is a planting method in which different crops or multiple crop combinations are planted sequentially between seasons or years on the same piece of land. Reasonable crop rotation can improve the soil, improve soil fertility, reduce the damage of diseases, insect pests and weeds, and ensure crop protection. output and improve economic efficiency. The amount of fertilization for cultivating cowpea is large, and a variety of nutrients are left in the field after harvesting, and long-term continuous cropping of cowpea will cause continuous cropping obstacles, while the existing rice fields are generally left idle after ripening and harvesting. Therefore, planting rice after harvesting cowpea can further utilize the nutrients in the field and achieve hig...
