If it is planted in a greenhouse, it needs to be outdoors day and night. Some vegetables can be cultivated by removing the side film and leaving the top film to avoid rain, which can reduce the temperature and humidity in the greenhouse and reduce the occurrence of diseases. Eggplants, fruits, vegetables and melons should be planted in turn on the same land, and the vegetable planting areas should be cleaned up on time to prevent the erosion of vegetables by pests and diseases and ensure the high quality and high yield of vegetables. Clean up the drainage ditches in time, keep them unblocked, reduce the groundwater level, and avoid vegetable waterlogging caused by excessive rainfall.
