Recently, the reporter discovered some vegetable farmers in Daotian Township, Shouguang City to bring the summer melons to market in advance. Tomatoes in the sheds have not yet been pulled out and will be planted with melon seedlings. Although this practice is good, certain key technologies must be mastered so as not to affect the growth and development of tomatoes and melons. The author believes that several points should be made: First, do not set the planting time too early. According to the experience of planting vegetables in previous years, the most appropriate time for planting vegetables should be carried out about half a month before the planting of Shangyu vegetables. If the set is planted too early, the seedlings will be kept in a sheltered environment for a long period of time. Not only the growth will be poor, but also old seedlings will be formed. In particular, the melons and vegetables should not be planted too early to prevent the vines from winding up on the unplanted plants. This not only results in difficulties in the extraction of the upper crops, but also affects the seedlings and vines due to their inability to promptly grow their heads. Therefore, vegetable planting must not be premature. Secondly, after planting vegetables, we should pay attention to sparsely picking up branches and leaves of the upper crop as much as possible to improve the light conditions of the set vegetables. To grow vegetables well, first of all, there must be sufficient light. Therefore, after the vegetables are planted, the branches and leaves of the upper crop should be removed as much as possible. At this time, most of the unopened vegetable plants on the shed are only the last one. Therefore, without too many branches and leaves to provide nutrition, the branches and leaves below the fruit can be removed as much as possible, so that the seedlings planted below can see more light. The better. Second, we must pay attention to temperature and humidity control should be based on planting crops. When growing seedlings, the young seedlings tend to have higher temperature and humidity requirements in the shed, and the control of temperature and humidity in the shed should be based on planting crops instead of worrying about not drawing shed vegetables in the shed so as to avoid small losses. . In addition, disease prevention should pay attention to set up a "small stove." In the later stages of vegetable growth, the diseases are often more frequent, and vegetable farmers often neglect management during this period, resulting in multiple diseases. Therefore, vegetable farmers must pay attention to disease prevention during this period, so as to avoid damage to the set of vegetables after the onset. In addition, the spraying of disease-preventing leaves should pay attention to open a "small stove" for the set of vegetable seedlings to ensure its normal growth.
