Kidney beans are commonly used vegetables. With the development of the vegetable processing industry, cowpeas, like some vegetables, are increasingly in short supply. How to increase cowpea production and improve the quality of cowpeas, combined with my personal experience in agricultural technology promotion, believe that we must grasp the following Key measures: 1, choose the right breed. In early spring and late autumn, the surface temperature is low and the sunshine is short. Some cold-tolerant and early-maturing varieties should be selected. The better-performing varieties are Yangjing 12, Lulutong No. 1 and so on. Summer sowing due to high temperature, long sunshine, should choose some heat-resistant varieties, the performance of better varieties are Yang Ye 40, Lu Lu Tong 2, and so on. 2, optimize formula fertilization. As the cowpea grows, the period of vegetative growth and reproductive growth is longer, so pay attention to the skillful use of basal fertilizer and foliar fertilizer. In the basal fertilizer, the proportion of phosphorus and potash fertilizers should be increased in an appropriate amount, and the proportion of nitrogen fertilizer should be reduced to prevent the legumes from being used in the later period and the flowering period should be shortened, thereby affecting the yield of cowpeas. In the later stage, in combination with pest control, the appropriate amount of foliar fertilizers can be increased. Extend the growth period of cowpea. 3, strengthen field management, pay close attention to pest control. Kidney beans are not afraid of stains, Qinggou drainage can not only promote healthy growth of cowpea, but also improve the disease resistance of cowpea. In July and August of each year, it is the prone period of kidney bean pests, and the main diseases and insect pests are downy mildew, rust, aphids, and cabbage caterpillars. The prevention and control methods are as follows: the disease is sprayed with bactericides such as fluomoran zinc and triadimefon; the insect pests are sprayed with Kaiwei 168, abamectin and the like. It should be noted that spray insecticide must be selected at 8 or 9 am to be effective for flowers, flowers and vines. In order to delay premature aging, 200 g/mu of potassium dihydrogen phosphate can be added to the solution to increase production.
