Detailed Explanation of Key Management Techniques for Wheat During the Wintering Period

Every autumn and winter is the period for planting winter wheat. As temperatures gradually drop, helping wheat get through the cold winter is an important measure in the winter wheat planting process. So how should wheat be managed so that it can overwinter safely? Follow the editor to take a look at the detailed introduction below.

1. Supplementary Fertilization

Due to different climatic conditions in different regions, the sowing time of winter wheat also varies. For wheat sown relatively late, many weak seedlings and small wheat plants will appear. These seedlings have poor cold resistance and are very likely to freeze to death. Therefore, before overwintering, topdressing should be carried out in time to promote seedling root growth and early tillering and earing, so that they can overwinter safely. Generally, before overwintering, apply 8-10 kg of urea per mu or 20 kg of wheat-specific fertilizer.

2. Proper Intertillage

Autumn is a rainy season. Long-term rain will cause soil compaction, and compacted soil has extremely poor air permeability, which will affect the normal growth of seedlings. Therefore, at this time, intertillage should be carried out in time to break up soil compaction, which can increase low temperatures and promote root growth. Intertillage can also remove weeds, so as to prevent weeds from competing for water and fertilizer. In addition, after watering, proper intertillage should also be carried out. For seedlings sown earlier and growing robustly, their roots should be cut off during intertillage to limit their growth, so as to prevent them from turning green too early and affecting later growth and yield.

3. Reasonable Irrigation

Winter irrigation is an important part of the wheat wintering period. Doing a good job of winter irrigation is beneficial for safe overwintering. This can not only prevent cold air from entering the soil and harming the roots, but also make the soil closely connected, increase soil temperature, and prevent hanging roots and frost damage. In winter, it should be carried out reasonably according to the growth status of seedlings, soil moisture, and climate changes. Under continuous drought and unknown soil moisture conditions, active drought-resistant irrigation should be carried out to make seedlings grow robustly. Where irrigation conditions exist, timely compaction should be carried out to preserve soil moisture, so as to prevent excessive seedling growth.

4. Do a Good Job in Pest and Disease Control

Although winter temperatures are relatively low, pest and disease control should not be taken lightly. Adhere to the control principle of prevention first, and at the same time do a good job in monitoring grass damage, so as to prevent weed infestation from causing weak or poor seedling growth. Before overwintering, weeds are younger, have lower resistance to chemicals, and the seedlings are small. At this time, chemicals can be sprayed to remove weeds, but attention should be paid to the safe interval period for spraying chemicals. Frequent spraying will cause chemical damage. At the same time, the correct pesticide should be selected and strictly used and operated according to the dosage in the pesticide instructions.
