When is winter wheat planted and harvested in the north?

Winter wheat is a crop with strong adaptability, short growth cycle and high yield. It is usually sown in autumn so that it can hibernate in the low temperatures in winter and grow rapidly when the spring warms up. Winter wheat is grown in both the north and south. So when is winter wheat planted and harvested in the north?

When is winter wheat planted and harvested in the north?

The sowing and harvesting time of winter wheat in the north is roughly as follows:

Sowing: September to November

Harvest: Late May to early to mid-June

The sowing time of winter wheat in the north is generally from September to November, and the harvest time is from the end of May to the beginning of June of the following year. Specifically, winter wheat in the Huanghuai and northern winter wheat areas is generally planted in early to mid-October and harvested from the end of May to early to mid-June of the following year. Wheat in the winter wheat areas in the middle and lower reaches of the Yangtze River is mostly sown from late October to early to mid-November, and harvested from late May to early June of the following year.

Field management measures for winter wheat

The field management measures for winter wheat mainly include the following aspects:

1. Check seedlings and replant

After the wheat seedlings emerge, the emergence status should be checked in time, and the plots with missing seedlings and broken ridges should be replanted in time to ensure that the seedlings are complete and uniform.

2. Pre-winter chemical control

When the soil moisture conditions are suitable after sowing and before budding, weed control should be carried out chemically. Most weeds emerge after wheat has 3 leaves before winter, and chemical weed control should be carried out at this time to control weed damage in wheat fields.

3. Repression

According to the moisture conditions and soil quality, suppress the soil at the right time to ensure that the seedlings are complete, uniform, neat and strong. The principle of suppression is “press dry but not wet, press light but not heavy, press soft but not hard”.

4. Loosen the soil to preserve moisture

During the greening period to the tillering period of winter wheat, loosen the soil and conserve moisture more than twice to improve water utilization efficiency.

5. Topdressing

According to the soil fertility and seedling conditions, apply nitrogen fertilizer in a timely manner to supplement the lack of base fertilizer or promote the growth of weak seedlings.

6. Watering

During the critical growth periods of winter wheat, such as the greening stage and the jointing stage, timely irrigation should be carried out to ensure appropriate soil moisture.

7. Weeding

Remove field weeds in time to maintain the purity of the wheat field.

8. Pest and disease control

During the seedling stage and after heading of winter wheat, it is necessary to prevent and control pests and diseases in a timely manner, such as aphids, stripe rust, powdery mildew, etc.

9. Apply more warm winter fertilizer

Spreading wheat bran, crushed wheat straw, etc. between wheat rows can help retain moisture and prevent frost. After rotting, it can also improve the soil and increase soil fertility.

In general, the growing cycle of winter wheat is relatively short, taking about 8 to 10 months from sowing to harvesting. Winter wheat can grow in low temperature conditions and can even tolerate a certain degree of freezing, which makes it suitable for planting in winter.
