How to manage wheat during overwintering period

Autumn and winter every year is the period of planting winter wheat, when the temperature drops gradually, if you help wheat through the cold winter, it is an important measure in the process of planting winter wheat. What about wheat if it can survive the winter safely during the period of management talent? Let's take a look at the detailed introduction with the editor.

1. Replenish fertilizer

Due to the different climatic conditions in different regions, the sowing time of winter wheat will also be different. For the late sowing time of wheat, there will be a lot of weak seedlings, wheat, these seedlings have poor cold tolerance and are easy to freeze to death. Therefore, before overwintering, it is necessary to apply fertilizer in time to promote the root growth of seedlings and tiller into spikes in advance in order to survive the winter safely. Generally, 8-10 kg of urea or 20 kg of special fertilizer for wheat are applied per mu before overwintering.

2. Proper ploughing

Autumn is a rainy season, long-term rain will lead to soil consolidation, the air permeability of the soil after consolidation is very poor, which will affect the normal growth of seedlings. Therefore, it is necessary to timely mid-tillage, break the soil consolidation, can increase the low temperature, promote root growth, in mid-tillage can also be weeding, so as to avoid weeds competing for water and fertilizer. In addition, mid-tillage should be carried out properly after watering, while the seedlings that sow earlier and grow healthily should hoe off its roots and limit its growth so as not to turn green ahead of time and affect its growth and yield in the later stage.

3. Rational irrigation

Winter irrigation is an important part of wheat overwintering period, and pouring overwintering water is beneficial to its safe overwintering, which can not only prevent cold air from entering the soil and harm the roots, but also closely connect the soil, increase the ground temperature and prevent the occurrence of hanging roots and freezing injury. In winter, it will be carried out reasonably according to the growth status of seedlings, soil moisture and climate changes. in the case of continuous drought and unknown moisture, it is necessary to actively resist drought and irrigation to make the seedlings grow healthily, while the irrigation conditions should be suppressed in time to preserve soil moisture so as to prevent the seedlings from flourishing.

4. do a good job in the control of diseases and insect pests

Although the temperature is low in winter, but for the prevention and control of diseases and insect pests should not be taken lightly, adhere to the principle of prevention and control, but also do a good job in the monitoring of grass pests, so as to avoid grass shortage leading to weak or poor growth of seedlings. Before overwintering, the grass age is less, the resistance to medicine is low, and the seedlings are small, herbicides can be sprayed at this time, but attention should be paid to the safe interval of spraying pesticides, frequent spraying will cause drug damage, and pesticides should be selected at the same time. Strict use and operation of the dose according to pesticide instructions.
