In the greenhouse vegetable production, how to arrange a one-year vegetable production in order to improve the utilization rate of the greenhouse, reduce production costs, increase economic efficiency, is a concern for producers. In production, blindly copying economically-efficient production gargles will not only fail to achieve good results, but will even backfire. For example, many vegetable farmers currently believe that the economic benefits of eggplant in winter and spring are better, but in actual production, many vegetable farmers do not meet the requirements due to winter greenhouse environmental conditions, or lack of management technology, causing serious economic losses. Therefore, vegetable growers should not be blind when they choose the type of vegetables to grow and determine the production of vegetables. They must pay attention to the following issues: First, we must select the appropriate types of vegetables according to the performance of our greenhouses and arrange vegetable production. For example, wintering cultivation of eggplants in greenhouses should be planted about one month before the coldest winter season and strive to complete the slow seedling growth period at the lowest temperature and begin fruit setting. In the early stage of flowering, the outside climate was in cold season. The temperature was low, and the light was insufficient. The management was mainly based on heat preservation. The daytime temperature was maintained at about 25°C and the night temperature was maintained at 15°C-18°C. If this requirement is not met, other relatively cold-tolerant vegetables should be reasonably selected. Second, it is necessary to choose the type of vegetable cultivation according to their own technical level and arrange vegetable production and gargle. If you choose a vegetable that exceeds your technical level and conditions, you must first understand the cultivation management method, first test the plant in a small area, master the basic management techniques, and then produce a large area. Blindly pursuing the production of "name and special" vegetables will easily result in losses. Third, when deciding on the types of vegetables to be grown, especially dilute special dishes, good sales must be considered. Otherwise, the production of rare vegetables that cannot be sold will also cause economic losses. Fourth, there must be a certain amount of time for fertilization before and after the cultivation of vegetables between the front and rear to ensure that they are well-prepared, fertilized, and strive to achieve high yields and quality. Pre-planting seeds and interplanting vegetables, the overlapping time can not be too long, as far as possible in the seedling period before the leek pull. As far as possible to raise seedlings in advance, to make time for the fertilization of the former crop, although some workers, but can do Miao Miao Zhuang, lay the foundation for high yield.
