Vegetable control oversaw
At present, with the gradual warming of the weather, the vegetables that have just been planted are growing very strong. To prevent the growth of vegetables, many vegetable farmers have taken measures to control the plant. However, some vegetable farmers did not grasp the balance when carrying out plant growth control. They oversaw their heads and caused the vegetables to be delayed. Therefore, to remind farmers friends, vegetable control chief must have degree, especially in the spring weather, so as to avoid the opposite. So, how can we control the length of vegetables in spring greenhouses? The following three points should be noted:
Try not to use growth regulators to control the length. The weather in spring is changeable, and there are cold springs. If you feel that vegetables grow quickly and spray growth regulators, if you change tomorrow, there will be a large temperature drop, which is easily caused by the dual effects of low temperature and growth regulators. Vegetable control is excessive.
The "three controls" commander must follow the weather. Controlling vegetables can also be achieved through temperature control, water control, and fertilizer control. When these measures are taken, they must also be targeted according to the weather conditions. If the weather turns cold, they should not consider tempering and controlling seedlings, but should mainly rely on insulation. In this way, the night temperature of the greenhouse, especially the temperature in the middle of the night, does not drop too low, thus causing the vegetables to suffer cold damage.
Root guaranty is too big. Some growers who grow melon vegetables use the method of controlling the length of the roots. This practice is good, but it needs to remind farmers to pay attention to the fact that the purpose of leaving the root melon is only to control the leggy, and should not be a small profit, will be listed after the root. In production, it was discovered that many vegetable farmers were overly greedy and felt that they had grown up. It would be better for them to pick and market them after they grow up, which in turn would cause the plants to let the roots of cucumbers fall to the trees and cause the plants to delay growing. This is not worth the candle.
