Reasonable close planting: Overwintering cowpeas are blocked in the low temperature and low light environment during the growth period. The photosynthesis is blocked and the nutrition of the plants themselves is limited. Therefore, the plants must not be too dense during planting to prevent the leaves from blocking each other. Generally take 70 cm, 50 cm size ridge planting, hole spacing 27-30 cm, 2-3 per hole, watering after planting, and spraying new high-fat film can effectively prevent the ground water from evaporating, the seed water is not transpiration, Isolation of pests and diseases, shortening the slow seedling period, allowing the plants to grow longer, covering the mulch after the slash. Field management: Strengthen the anti-freezing measures in winter, strengthen the lighting of the greenhouse, often wipe the film and improve the transparency; in the management of fertilizer and water, it should be watered as little as possible, and spray the flower on the 3rd to inhibit the main shoots and promote the flower buds. Differentiation; before the flowering of the cowpeas and before the flowering of the cowpeas, 15 kg of ammonium sulfate was applied in the mu, while spraying the fruit and fruit to improve the pollen quality, enhance the cycle fruit setting rate, and topdress every 10-15 days during the pod-forming period. Apply 15-20 kg of ammonium sulfate each time. After the flowering, the carbon dioxide gas fertilizer can be applied in the sunny day, and the air is properly ventilated for 2 hours after the application; the senescence of the plant in the late growth stage of the cowpea, the root aging, in order to prolong the pod formation, the spray can be sprayed with 0.2% potassium dihydrogen phosphate plus a new high fat film 800 times liquid. Face fertilization. After the peas are stretched out, the vines are erected in time, and then smashed and smeared in time. Try to avoid blocking each other between the leaves. When the plant height is 2-2.5 meters, pick the heart in time to promote pod formation. Pay attention to destroy the lower old leaves after each harvest. Prevention and control of pests and diseases: Beans planted in greenhouses, due to low temperature and high humidity environment, poor ventilation, rust disease, leaf mites, anthracnose, leaf spot, etc., pests mainly include aphids and pea pods, should be sprayed with targeted drugs in time The new high-fat film can improve the efficacy, achieve the best control effect, reduce the number of pesticide spraying and pesticide residue.
