Agricultural greenhouse vegetable cultivation technology analysis, what are the main points and points for attention? Since entering the 21st century, the development of science and technology in our country has been more and more rapid, which has greatly promoted the social production and development of our country, and also has a very positive role in promoting the development of all walks of life. In the course of agricultural production in our country, the cultivation and planting of greenhouse vegetables can provide more fresh vegetables for people in winter, and improve people's quality of life effectively, there are some deficiencies in yield and quality.

Industry economy is an important basis of our national economy, so with the development of our economy and science and technology, our agricultural production has been further developed. In the current agricultural production process in our country, the agricultural greenhouse vegetable cultivation work has been very widespread, for our country's off-season vegetable cultivation and the improvement of People's living standards have made an important contribution, but the traditional agricultural greenhouse vegetable planting technology is relatively low, and the yield is also relatively low. Therefore, in the current agricultural greenhouse vegetable planting process, it is necessary to carry out further research on its cultivation technology. In the process of cultivation and planting, the choice of greenhouse location will also affect the final output of vegetables, which mainly takes into account the natural conditions of the greenhouse location. Therefore, when selecting the location of the greenhouse, the local soil and water environment should be taken into account first, the soil acidity, alkalinity and nutrient composition of the area should be taken into account, and the water source condition of the location should also be taken into account, considering the sufficiency and quality of water source, the greenhouse can provide sufficient and high-quality water source for later vegetable planting after the location is selected. Second, soil selection, in the process of planting vegetables in agricultural greenhouses, the quality of the soil will directly affect the yield of vegetables, so before planting, it is necessary to test the soil conditions in the region, to detect the nutrients in the soil and the situation of plant diseases and insect pests, to ensure the healthy and rapid growth of vegetables in the soil and reduce the threat of plant diseases and insect pests.

3. Select good varieties. In the process of planting vegetables in agricultural greenhouse, if we want to increase the yield of vegetables, we still need to select the varieties of vegetables reasonably, high-quality varieties of vegetables and high-quality seeds of vegetables, can effectively improve the yield of vegetables. Therefore, before sowing the vegetable seeds, it is required to analyze the soil, water and light conditions in the greenhouse first, so as to fully understand the growing environment in the greenhouse, and then take this as the basis, select the highest yield in this environment, the most easy to survive vegetable varieties.

Fourth, scientific fertilization, fertilization is an important way to promote the rapid growth of vegetables, so to improve the yield of greenhouse vegetables, but also the need for scientific fertilization. In the process of vegetable growth, the nutrients in the soil are often difficult to meet the needs of vegetable growth, so in the process of vegetable growth, growers must be based on their specific growth conditions, select the appropriate fertilizer for fertilization, for the growth of vegetables to provide adequate nutrients. In the process of growing vegetables in pest control, the problem of pests and diseases is also an important problem that affects the growth and yield of vegetables. Therefore, in the process of growing vegetables in greenhouses, growers must do a good job of pest control, strengthen the pest control work in the later stage, and carry out corresponding prevention and control work targeting at the varieties of vegetables in the greenhouses and the diseases and pests that are prone to occur, effectively combining physical control, chemical control and biological control measures, when choosing chemicals, we should try our best to choose chemicals that do little harm to vegetables, so as to prevent them from affecting the quality of vegetables. In conclusion, as an important agricultural mode of production, greenhouses can effectively improve the quality and yield of agricultural products, especially for out-of-season cultivation, at present, in the course of agricultural production in our country, the planting of vegetables in agricultural shed has been popularized, which has effectively improved people's quality of life, but in the process, the low level of technology makes its output can not be effectively increased. Therefore, in the process of planting vegetables in agricultural greenhouse, we must strengthen the research of cultivation technology, through the improvement of planting environment, cultivation technology and management, effectively improve the yield of vegetables in agricultural greenhouse.
