The management of greenhouse vegetables in winter should focus on temperature and humidity regulation and control, combined with fertilizer and water management. Keep warm and warm. In winter, the climate is cold and the temperature is low. Therefore, it is the key to the management of vegetables in greenhouses in winter. In the production, multi-cover cultivation technology is usually adopted, and a new high-fat film is sprayed on the vegetable surface to insulate the anti-pathogenic bacteria. The ground covers the mulch film to increase the heat capacity of the soil; the straw curtain is covered on the shed film, and a plastic film is added on the straw curtain to prevent the rain and snow from drenching the straw curtain and effectively improve the temperature inside the shed. Adjust the humidity. At the same time, taking measures to keep warm and keep out the cold, it is also necessary to uncover the film ventilation according to the weather conditions and adjust the temperature and humidity reasonably. When the crops in the shed are diseased, the control agent can give priority to the new high-fat film + bactericide, which has the effect of preventing the infection of the bacteria. The application of organic fertilizer to organic fertilizer can promote the cold resistance of the plant, and also has a certain warming effect on the soil at the root of the plant. At the same time, the vegetables in the shed can be sprayed with vegetables, strong stems and foliar fertilizers, which can improve the ability of resisting disasters, reduce the amount of pesticides and fertilizers, reduce residual toxicity, and enhance the ability of cold resistance.
