    What are the main points and precautions for agricultural greenhouse vegetable cultivation technology analysis? Since entering the 21st century, my country's scientific and technological development has become faster and faster, which has greatly promoted my country's social production and development, and also has a very positive role in promoting the development of all walks of life. In the process of agricultural production in my country, the cultivation and planting of greenhouse vegetables can provide people with more fresh vegetables in winter and effectively improve people's quality of life. However, traditional agricultural greenhouse vegetable cultivation has certain aspects in terms of yield and quality. insufficient. Discuss the vegetable cultivation technology in agricultural greenhouses to increase the vegetable output in agricultural greenhouses.

     1. Reasonable site selection 　　

    In the process of vegetable cultivation and planting in agricultural greenhouses, the selection of the location of the greenhouse will also affect the final vegetable output, which mainly takes into account the natural conditions of the location of the greenhouse. Therefore, when selecting the location of the greenhouse, the local soil and water source environment must be considered first, and the pH and nutrients of the soil in the area must be considered; the water source conditions of the location must also be considered, and the water source must be considered. The adequacy and water quality ensure that the greenhouse can provide sufficient and high-quality water for the later vegetable planting after the location is selected. Finally, in the process of selecting the location of the greenhouse, the topography and topography of the location should also be considered. This will have an important impact on the drainage work in this area, preventing droughts and floods in the process of planting vegetables in greenhouses.　

     2. Soil selection 　　

    In the process of planting vegetables in agricultural greenhouses, the quality of the soil will directly affect the yield of vegetables. Therefore, before planting, it is necessary to test the soil conditions in the area to detect the nutrient content in the soil and the status of diseases and insect pests to ensure that the vegetables It can grow healthily and quickly in the soil, reducing the threat of pests and diseases. In addition, in the process of planting vegetables in greenhouses, in order to improve soil quality and soil conditions, it is also necessary to improve the cultivation methods, and try to use rotation and fallow to maintain soil fertility. Vegetable crops that are prone to pests and diseases should be planted in quarters. The planting area should be divided according to the types of vegetables to increase vegetable production.　

    Three, choose good varieties 　　

    In the process of planting vegetables in agricultural greenhouses, if you want to increase the yield of vegetables, you also need to make a reasonable selection of vegetable varieties. High-quality vegetable varieties and high-quality vegetable seeds can effectively increase the yield of vegetables. Therefore, before planting vegetable seeds, it is required to analyze the soil, moisture and light conditions in the greenhouse to fully understand the growth environment in the greenhouse, and then select the vegetables with the highest yield and the easiest to survive in this environment based on this Variety. In addition, in the process of buying vegetable seeds, growers need to purchase from regular channels, and keep the purchase invoice and related certificates, and scientifically select seeds before sowing to ensure the quality of the seeds.
