According to relevant persons from the Vegetable Technology Promotion Station, the traditional method of cultivation of greenhouse vegetables is often low yield and poor efficiency. If the following five measures are used, the yield and benefits of greenhouse vegetables can be doubled. Change the ordinary film cover to a dripless film cover. The use of non-dropping membranes allows the water to flow down the membrane surface, which will not damage the plants due to water droplets, but also reduce the "water source" of water vapor evaporation in the greenhouse and reduce the humidity in the greenhouse. During the filming process, the film must be stretched and flattened. The second change was planted into ridges. The ridge planting can expand the light receiving area and increase the ground temperature, forming a loose soil layer that is conducive to the growth and development of vegetables, ensuring the normal growth of the root system, and can also enhance the ability to resist drought and drain water. Three changes to ordinary cultivation as a cover film cultivation. Covering the mulching film is conducive to warming and moisturizing, enhancing the ability to resist disasters, avoiding the loss of soil and fertilizer, reducing pests and diseases, and speeding up the decomposition of fertilizers. Four pesticides sprayed to prevent and treat pests and diseases with dust or aerosols. The occurrence of diseases and insect pests in greenhouses is frequent, and the number of sprays of pesticides is large and the number is large. The use of dust and aerosols will greatly reduce the drawbacks of high humidity caused by the spraying method, and it may have the effect of reducing moisture and preventing disease. Five changes to direct seeding cultivation for nutrition seedling transplanting. Compared with direct seeding cultivation, the use of nutrient seedlings to transplant seedlings has many advantages. When transplanted, the roots of the plants are not susceptible to injury, and there is basically no seedling-reducing period, which facilitates the direct growth of the plants, the nutrition of the plants is sufficient, and transplanting is convenient.
