In the autumn and autumn, after delaying the planting of vegetables, effective suppression of growth is the key to management. However, in recent days, the temperature has decreased rapidly. If farmers still adopt the conventional method of controlling luxuries, they are prone to overcontrol. Then, how should it be alleviated? At the same time, which relatively safe control measures should be taken?

There are two ways to alleviate excessive hyperactivity: First, vegetables with a slightly higher degree of control may be mitigated by environmental regulation. If appropriate increase in the number of watering, spray nitrogen fertilizer foliar fertilizer, or turn off the small tuyere to improve the night temperature and promote the rapid growth of vegetables. The second is to control serious vegetables, it is recommended to use conditioners to ease, and at the same time with the previous environmental control measures, the effect is better. Therefore, the current season vegetable control measures should be more flexible and flexible, specific can be expanded from the following aspects:

First of all, physical control measures are adopted to effectively regulate the growth of vegetables that are less prosperous. From the management aspect, one is to reduce the number of watering, pull the tuyere to lower the night temperature, etc.; second, to tilt the plant, weaken the top dominance, such as tomatoes; third, increase the amount of fruit left or appropriate delay in picking the fruit; Fourth, reasonable pruning杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈 杈. Followed by the use of balanced growth regulators. Some conditioners currently on the market have a two-way adjustment function and only need to be used when used. Such as love overtake (sodium nitrophenolate) 3000 times, 600 times cytokinin, seaweed products 500-600 times, amino acid leaf fertilizer such as photosynthetic power 300 times, conventional potassium dihydrogen phosphate 300 times, can play Balance the purpose of growth and control.

Once again, it is the use of anti-Wang drugs. This requires the combination of vegetable growers to grow and choose the appropriate control agent and concentration to avoid excessive control. Commonly used Wang control agents are chlormequat, auxin, chlorophyll, paclobutrazol, etc. When spraying, it is also necessary to pay attention to the combination of weather conditions, to avoid rainy weather after the use of drugs, to avoid the occurrence of phytotoxicity or excessive control of the situation. In addition, spraying some azole drugs can also play a certain role in inhibiting growth.
