Summer cowpea refers to the cowpea planted at a high temperature of 35 degrees during the peak harvest period. Due to the high temperature, small temperature difference and heavy rainfall of this crop of cowpea, the pods are prone to bulging seeds and serious diseases and insect pests. Therefore, cultivation techniques are different from spring. The goal of cultivation is not to pursue high yields, but to have good commodity properties, strong disease resistance, and the color of the strips to suit the consumption habits of the market. Generally pay attention to the following links. Cultivation techniques of cowpea in summer 1. Variety selection: On the basis of ensuring that the color is suitable, the high temperature does not bulge the seeds, and the disease resistance is strong, try to choose rich varieties. 2. Land preparation and fertilization: Apply 30kg of three-element compound fertilizer per mu, and 2 cubic meters of decomposed organic fertilizer. When plowing the land, apply 3% phoxim granules 7000g per mu to prevent and control underground pests. Three, sowing: Seed 1.5kg per mu. The density is sparser than spring planting. Plant 2800 holes per mu, with 2-3 seeds per hole, and plant two rows with 1.5m row spacing and 30cm plant spacing. Dry seeds are generally used for direct seeding. 4. Seedling management: The seedling period of summer cultivation is very short, only about 20 days from the emergence of the seedling to the throwing of the vine. The main points of management are disease prevention and fertilizer control. Generally, 40ml 10% myclobutanil EC is used to irrigate roots to prevent cowpea rot. 5. Climbing period management: From vine rejection to full-frame management, the main focus is on water and fertilizer control, and the soil moisture content is maintained at 60-70%. Do not fertilize until half of the rack is covered. Pay attention to the prevention and control of diseases and insect pests. Generally, 20% fenvalerate EC is used. When the rainfall is heavy, spray 80% carbendazim powder and other protective fungicides. When the plant growth point exceeds the frame, topping and topping in time. 6. Management of pod setting period: 1. Keep up with water and fertilizer management, especially nitrogen fertilizer. Generally, apply 10-15kg of urea per mu, 40cm away from the plant, and water in time after application. 2. Reasonable and safe use of pesticides to prevent and control pests. Prohibit the use of highly toxic pesticides Generally use highly effective and low-toxic pesticides, such as cypermethrin EC, fenvalerate EC, etc. 3. It is to prevent and control diseases. Mainly anthracnose, leaf spot and powdery mildew. Generally, use 70% thiophanate methyl 700-800 times liquid, 80% mancozeb 800 times liquid and other broad-spectrum fungicides, 15% Pyrinin EC 1000 times liquid, to ensure that the medicine is sprayed once after a rain. 4. Reasonable use of foliar fertilizer can make the pods more beautiful. Commonly used foliar fertilizers include vital element, strong and multi-harvest, green tyrant and so on.
