First, the selection of varieties of autumn cowpea should be used in heat-resistant, disease-resistant, adaptable, and high scab rate varieties, such as new varieties of high-yield low-quality cowpea - Didou Wang No. 1, Fengshou No. 1, Japanese white pellets And other cowpeas. Second, timely sowing autumn cowpea to grasp the appropriate sowing time, sowing too early, the flowering period of high temperature, easy to drop flowers and falling, rust serious; sowing too late, short growth period, low yield. The common pod beans should be sown from the end of June to the beginning of July. The dwarf peas have a short growing period and can be sowed for several days. Third, a reasonable close planting of the early period of the growth of autumn cowpea, the higher the temperature, the main plant vines grow faster, internode long, after the temperature is getting lower, fewer collaterals occur. When planted live, it can be densely planted to increase the number of plants per unit area and increase production. The general spacing is 60 centimeters, and the distance between the holes is about 20 centimeters. The ridges are sowed in pods, with 2-4 seeds per hole. Fourth, the introduction of vines on the shelves in summer and autumn, high temperatures, rapid growth of stems and leaves, vines, beans must be promptly inserted vines, in order to facilitate field ventilation and cooling. Fifth, Fertilizer and water management Autumn cowpea seedlings is the high temperature season, evaporation, water needs, should be timely watering, moisturizing cooling. After the rain, water should be poured in a timely manner to reduce the temperature of the ground and supplement the oxygen in the soil, and remove water. Autumn cowpea flowering early, appropriate control of water, to sit after the increase in watering. Combined with water and phosphorus potassium fertilizer, top 10 kg per acre. 6. Pest control diseases mainly include anthrax and rust. Rust mainly occurs in late and late stages of bean growth and mainly affects the leaves. In severe cases, stems, vines, petioles, and pods can be affected. The leaves and stems were infected. The appearance of chlorotic yellow spots at the edges was not obvious, and the diameter was 0.5-2.5 mm. The pods were infected to form prominent epidermis ecchymosis. After the epidermis ruptured, brown spore powder was emitted, namely the teliospore and teliospores. Anthracnose 80% anthrax Fumei wettable powder 600 times, 70% mancozeb WP wettable powder 500 times liquid spray control, once a day for 7 days, even spray 2-3 times; rust use 25% triadimefon wettable powder 2000 times, 50% rust rust EC 800 times liquid prevention. Control locusts and spider mites can be sprayed with 40% dimethoate EC 1500 times. 7. After harvesting the dwarf cowpeas, the harvested pods will begin to be harvested after about 40 days. The pod beans will be harvested in 40-60 days and harvested in time.
