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 the output of cowpeas and improve the quality of cowpeas, the author combines many years of practical experience, believes that the following three Key technical measures: 1, select good off: Early spring, late autumn low surface temperature, short sunshine, should choose some cold-resistant early maturing varieties, the performance of a good variety of Yang Yan 12 and so on. Summer sowing because of high temperature, long sunshine, should choose some heat-resistant varieties, the performance of a good variety of Yang Lan 40 and so on. 2, formula fertilization off: cowpea vines, vegetative growth and reproductive growth longer, so pay attention to basic 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, the combination of pest control and appropriate application of foliar fertilizers can be increased. Extend the growth period of cowpea. 3, field management: pay close attention to pest control, cowpea afraid of stains, clearing drainage can not only promote the healthy growth of cowpea, but also improve the 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.
