How to manage wheat during the overwintering period? The latest technical key points are here
Every year's 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 to overwinter safely? Follow the editor to take a look at the detailed introduction.
1. Supplementary fertilization
Because the climate conditions of each region are different, the sowing time of winter wheat will also differ. For wheat sown later, many weak seedlings and wheat plants will appear. These seedlings have poor cold resistance and are very likely to freeze to death. Therefore, before overwintering, fertilizer should be applied 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 special wheat fertilizer.
2. Proper intertillage
Autumn is a rainy season. Long-term rain will cause soil compaction. 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 the compacted soil, which can increase low temperature 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 vigorously, 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 overwintering period. Good overwintering water is beneficial to safe overwintering. This can not only prevent cold air from entering the soil and harming the root system, but also make the soil closely connected, increase soil temperature, and prevent suspended roots and frost damage. In winter, it should be carried out reasonably according to the growth status of the seedlings, soil moisture, and climate changes. Under continuous drought and unknown soil moisture conditions, active drought-resistant irrigation should be carried out to make the 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 the temperature in winter is relatively low, pest and disease control should not be taken lightly. Adhere to the prevention-oriented control principle, 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, the grass age is relatively young, its resistance to chemicals is relatively low, and the seedlings are small, so chemicals can be sprayed to remove weeds at this time, 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 it should be strictly used and operated according to the dosage in the pesticide instructions.
