Although the bean varieties suitable for greenhouse cultivation are not strict with the requirements of the light hours, the light intensity requirements are relatively high, especially during the flowering and sitting pods, if the light is insufficient, the beans will fall into the pods. Because the growth of the bean seedlings is in a low temperature and low light environment. Planting a new high-fat film and watering it to prevent infection of the bacteria and increase the photosynthesis intensity. Then paddle and cover the entire film. After the bean vines are inserted into the frame, all the scorpions below the first ear flower can be erased. When the main vine climbs to the top of the frame, the heart is picked, and the later side pedestal pods are also topped. The main vine picking promotes the growth of the side branches, and the smearing and side branching promote the growth of the beans. The suitable growth temperature of the beans is 20 ° C ~ 25 ° C. During the flowering period of the beans, the daytime temperature and the nighttime temperature and the temperature difference between day and night should be mastered. The standard of the bean buds in the pods is shed at 17 °C, and the stalks are sprayed on the beans to grow the pollen. Fertilization quality, improve fruit yield and quality, reduce the rate of fruit drop, reduce the incidence of cracked fruit, stiff fruit, and abnormal fruit, so that the fruit and fruit can be produced in succession. Field management should be strengthened during the bean growing season. Appropriate close planting, ventilation and light transmission, increase the application of phosphorus and potassium fertilizer, improve the disease resistance of the plant, spray the targeted agent on the early stage of the disease to prevent and control the bean worm, and then cooperate with the new high-fat film to inhibit the virus replication and improve the control effect, interval 7- 10 days, continuous spraying 2-3 times.
