After the autumn and autumn vegetables are fixed, the effective suppression of the longevity is the key to management. In recent days, the temperature has decreased rapidly. If the vegetable farmers still use the conventional method of controlling the Wang, it is easy to have excessive control. Then, how should it be alleviated? At the same time, what relatively safe control measures should be taken?
First of all, the method of physical control is adopted to effectively regulate the growth of vegetables with a long period of difference.
From the management point of view, the first is to reduce the number of watering, pull the tuyere to reduce the night temperature, etc.;
The second is to tilt the plants and weaken the top advantages, such as tomatoes;
The third is to increase the amount of fruit remaining or to delay the picking of fruit; the fourth is to rationally pruning and snoring, and properly retaining some of the side branches and deformed fruit and other plant-consuming nutrients, which can play a certain role in controlling the stagnation.
The second is to use a regulator of balanced growth. As we all know, some regulators currently on the market have the function of two-way regulation, and only need to pay attention to the dosage when using, which can achieve the purpose of regulating plant growth.
Then use the control agent. This requires the vegetable growers to combine the growth of the plants, choose the appropriate control agent and concentration, to avoid excessive control. Commonly used control agents have chlormequat, auxin, chlorophyll, paclobutrazol and so on. When spraying, it is also necessary to pay attention to the weather conditions, avoid the rainy weather after the medication, and avoid the occurrence of phytotoxicity or excessive control.
In addition, spraying some azole drugs can also play a certain role in inhibiting growth.
