The early growth stage of autumn soybean in greenhouse is in hot summer, so we should pay attention to shading and cooling, and open all vents in greenhouse to ventilate day and night to avoid excessive temperature, which will lead to poor growth, few pods and low yield. After September, as the temperature drops, it is necessary to reduce the ventilation volume and shorten the ventilation time. 10 months later, ventilation should be stopped at night. In June, 5438+065438+ 10, the temperature in the shed is low at night, so it is necessary to strengthen cold protection and heat preservation and extend the growing period as much as possible. In the management of water and fertilizer, we should pay attention to rain protection after the seedlings are unearthed, and cover the greenhouse tightly to prevent the seedlings from being watered by rain. Because the temperature is high and the evaporation is large at this time, water it often, preferably once in the morning and once in the evening. Prevent seedlings from falling flowers due to excessive growth, and at the same time strengthen intertillage drainage to prevent waterlogging. After pod setting, topdressing should be started, with topdressing every 10 ~ 15 days 1 time. It is best to combine irrigation with fertilization. When tendrils appear in plants, they can stand upright and tie, and generally adopt single-row support. Because peas have many stems and vines, they can't wrap themselves, so bamboo poles and nylon ropes are often used to support and bind the vines. The method is as follows: erect a 1 bamboo pole every one meter, wind a 1 nylon rope on the bamboo pole every 0.5m, let the peas climb each other, and then tie the rope around the waist to fix it. When the plant grows to 15 ~ 16 nodes, it can be picked in sunny days.
