Reasons and Methods of Controlling Wheat Prosperity

I believe that many people do not understand the word wheat prosperity control. The original understanding of wheat prosperity control is to control wheat growth, so why control wheat growth? How to do it? "Let's get to know it with the editor.

First, the reasons for the control of wheat prosperity

1. Easy to suffer frost damage in winter and spring

Because vigorous growth will accelerate the growth of wheat into the city, resulting in delicate seedling growth, more stems and insufficient sugar storage in tillering nodes, especially after the young spike differentiation enters the two-edge stage, the freezing resistance of wheat is obviously weakened. it is extremely vulnerable to low temperature freezing injury in winter and cold in spring, dead leaves and dead tillers in light and dead seedlings in frozen ears.

2. Easy to lodge

The seedlings have vigorous growth, more tillers, large leaves, poor field permeability, delicate plants, long basal internodes, thin stem wall, less dry matter accumulation, poor root development, less secondary roots and shallow entry into the soil. If there are more Rain Water in spring or if there is a storm in the middle and later period, the rhizome is easy to lodge and suffer serious losses.

3. Diseases are easy to occur

Under the condition of high temperature in autumn and winter, the number of pathogens in the field is more, the quality of external seedlings is low, and the disease resistance is insufficient. Under suitable environmental conditions, diseases such as sheath blight, powdery mildew and root rot are very easy to occur.

Second, the method of controlling prosperity

1. Suppression and control of prosperity

Repression has the effect of controlling up and promoting down, mainly bruising the aboveground leaves, delaying the growth, and promoting the root system to tie down to the depths of the soil. Suppression can be carried out with ballast, oil barrel filled with sand or rake, and the suppression must be carried out around noon on a sunny day. During the crackdown, we should pay attention to the wet ground, and do not press it if there is dew or when the soil freezes. Many crackdowns should be carried out in the same direction.

2. Chemical control

Spraying chemical additives on wheat can effectively increase the cell sap concentration of wheat leaves, inhibit the elongation of basal internodes, and effectively improve the ability of frost resistance and lodging resistance of wheat.

3. Control prosperity by ploughing.

Deep hoeing and root cutting can be adopted for the prosperous land with large population, which can also restrain the growth of wheat and control the growth of wheat. In general, ploughing in the wheat field can keep heat and increase temperature and promote the development of the root system. after the wheat turns green, make use of the gap between the rising temperature and draw a hoe in time after the soil is thawed at noon, so as to cut off the thin tube of the root, reduce the evaporation of soil water, and make the soil compact. can it effectively improve soil temperature, promote root development, and weed.

The above is the introduction of the reasons and methods of wheat prosperity control. I hope it can help you. If you want to know more about it, please follow us.
