Management of wheat during winter

As the temperature gradually decreases, the growth rate of wheat will slow down and enter a dormant or semi-dormant state. In order to ensure the yield and variety of wheat, management during the wintering period is very important. The following editor will introduce the management of wheat during the wintering period. Let’s take a look.

1. Check the seedlings and replant: If there are missing seedlings and broken ridges due to missed seeds, lack of moisture, underground pests , etc., the seedlings should be checked and replanted in time to ensure that the seedlings are complete and uniform.

2. Eliminate diseases and pests in the seedling stage: Common diseases and pests in the seedling stage include locusts, planthoppers, underground pests, leaf rust, etc. Once discovered, they should be prevented and controlled in time.

3. Pressing down the needles: After wheat enters the three-leaf stage, pressing down the needles is a powerful measure, that is, suppressing it once during the three-leaf stage to control the main stem, promote tillering, control the ground, and promote the root system.

4. Loosen the soil and shake the wheat: If it rains during the tillering period, you should loosen the soil and shake the wheat in time to help break up the compaction and promote root growth. For vigorous seedlings, the digging should be more than 7 cm deep, which can help cut off the roots and control their growth.

5. Water well in winter: Apply top dressing as appropriate. Winter irrigation should be timely. It usually starts when the average temperature is 7℃-8℃ and ends at around 5℃, which is the time when the night frost melts during the day. The amount of water for winter irrigation should not be too large. It is better to water thoroughly and let it seep in on the same day.

6. Watering in winter: Watering can be done from winter to before the soil turns green again. Water as the soil accumulates. Generally, about 500 kilograms of urine are used for every 667 square meters. It is not suitable to water when there is snow in saline-alkali land or wheat fields.

7. Covering: This should be done after wheat enters the wintering period. Use a bamboo rake to rake the soil along the ridges in the large rows and cover the wheat seedlings with about 2 cm of soil. This technical measure can stabilize ground temperature, reduce soil moisture evaporation, and ensure that wheat stays green over the winter.

8. Suppression: The wheat should be rolled 1-2 times after covering and before it turns green again to break up the clods and make the soil fine and compact. This is beneficial to eliminate compaction and cracking, keep warm and retain moisture, and pull the soil to fill cracks to prevent air leakage.

9. Chemical weeding: Chemical weeding should be carried out as early as possible in the seedling stage. In mid-to-late November, use 10% bensulfuron-methyl wettable powder 10-15g/mu, or when the weed seedlings have 3-5 leaves in the early stage of regreening, use 87.5% 2,4-D isooctyl emulsifiable concentrate 40-50ml/mu, or 10% oxadiazon-butyl emulsifiable concentrate (containing safener) 50-60ml/mu, add 30-40kg of water and spray.

10. Apply more warm winter fertilizers: Before winter, spread 250-300 kg of wheat bran, broken wheat straw, etc. per mu between wheat rows. They have the functions of retaining moisture and preventing frost. After they rot, they can also improve the soil and enhance soil fertility.

The above is an introduction to the management of wheat during the wintering period. The management of wheat during the wintering period is crucial to the growth and yield of wheat. For vigorously growing wheat fields, measures such as suppression, hoeing, and spraying of growth control agents should be taken to control the growth of the above-ground part and promote root development.
