Try not to control the length of plant growth inhibitors Because of the changeable weather in the spring, there is a time when the cold is occurring. If you feel that vegetables grow quickly and you spray growth inhibitors today, if you change tomorrow, there will be a large temperature drop. Under the dual effects of low temperature and growth inhibitors, it is easy to cause excessive vegetable growth. Therefore, it is important to avoid applying plant growth inhibitors as far as possible to prevent vegetable growth in spring, so as to avoid adverse effects on vegetable growth. "Three controls" should be In addition to spraying plant growth inhibitors, the control of vegetable growers can be achieved through temperature control, water control, fertilizer control and other "three controls" measures. When these measures are taken, they must also be targeted according to the weather conditions so as not to have the opposite effect. If the weather suddenly changes, it is better not to consider temperature control and seedling control. Instead, it should be based on insulation. In this way, the night temperature of the greenhouse, especially the temperature in the middle of the night, should not fall too low, so as to avoid cold damage to the vegetables. Root guaranty should be cautious Some growers who grow melon vegetables use the method of controlling the length of the roots. This approach is good, but it needs to remind farmers to pay attention to the fact that the purpose of leaving the root melon is to control the leggy, and should not be used for the purpose of plotting small profits and selling the money after leaving the market. Many vegetable farmers are overly greedy and feel that the root melon has grown very large. It is better to let the root melon grow and be picked and listed, which will cause the plant to let the root melon fall to the tree, causing the plant to delay the return of the tree, which is not worth the candle.
