Pepper is rich in nutrition and is a favorite vegetable of consumers. With the success of pepper cross breeding, it further promoted the production of pepper. Using plastic greenhouse to cultivate pepper can effectively advance the market period and increase the yield and total output in the early and middle stages, so as to achieve the purpose of increasing both yield and income. Therefore, the comprehensive high-yield cultivation of pepper in greenhouse is a feasible advanced technology, especially strengthening the management in the following aspects during cultivation and planting, which is conducive to increasing the yield and income of pepper. First of all, we should pay attention to temperature management in greenhouse pepper planting. The temperature should be controlled at 26 ~ 30℃ during the day and18 ~ 20℃ at night 3 ~ 5 days before the slow seedling stage, so as to rapidly increase the ground temperature, which is beneficial to rooting, and at the same time, spraying 6000 times of Stockholm on the leaves continuously for 7 ~10 days to promote root growth and flower bud differentiation, laying the foundation for high yield in the later period; After that, the pepper plants began to grow vigorously, and the temperature was controlled at 25 ~ 28℃ during the day and15 ~18℃ at night. Pay attention to heat preservation after entering the deep winter, and you can apply a second film for heat preservation. As the weather gets warmer, we should gradually increase the ventilation. Ventilation to cool down, the daytime temperature should not exceed 30℃, and the temperature should be 23 ~ 28℃, and the night temperature should be18 ~ 23℃. By mid-April, if the temperature has risen steadily, the grass can be left uncovered at night. When the lowest outside temperature is stable above 15℃, the shed membrane at the foot should be uncovered for day and night ventilation. Pepper grows rapidly and develops normally at 20 ~ 30℃, which is lower than 15℃ or higher than 35℃, and its pollen pollination is not easy, which will seriously affect its fruit setting. Therefore, the shed should be closed for 5 ~ 6 days after planting, so as to improve the shed temperature and tighten the film pressing belt to avoid the wind from breaking the shed film. After the seedlings survive, properly uncover the greenhouse membrane at the junction with the skirt membrane for ventilation in fine weather. In the future, when the pepper enters the flowering and fruit-setting stage, it is necessary to uncover more films to increase ventilation to help the spread of pollen. When the temperature outside the greenhouse is stable above 25℃, all the films should be uncovered to reduce the greenhouse temperature, promote the spread of pollen and improve the fruiting rate. Spraying 6000-fold solution before each flower to improve pollination quality, promote cell division, correct fruit shape and reduce abnormal fruit!
