Can wheat stand the recent big temperature difference?

The temperature difference between June 5438 and February 2023 was large, and wheat could stand it.

Since 1 1.4, there has been an obvious process of strong wind, cooling, rain and snow in northern China. This cooling is mainly concentrated in the north of the Yangtze River, and the northeast region is the most seriously affected. The minimum temperature may drop to MINUS 5~8℃. For the main producing areas of winter wheat, people are concerned about whether the cooling weather will bring freezing damage to winter wheat seedlings and how much impact it will have on winter wheat.

But in fact, this drastic cooling will not cause freezing damage to winter wheat. Although the temperature has dropped greatly, the lowest temperature in winter wheat planting area is still above 0℃, far from freezing injury zero. Therefore, this cooling has no effect on winter wheat seedlings, and even brought many benefits.

Matters needing attention in wheat planting

1, pay attention to seeds in advance.

Seeds must be dried three days in advance, and the speed of seed emergence will directly affect the growth of seedlings. The slower they appear, the more nutrients they consume in the soil, and the easier it is to get sick. Therefore, only by selecting high-quality seeds and waking them up in advance can the seeds germinate faster.

2. Pay attention to the sowing depth

Pay attention to the sowing depth when sowing, and control it at about 3 cm, so that it is easy to absorb water and is conducive to the emergence of seeds. The ground must be leveled before sowing, so as to ensure the uniformity of wheat field emergence.

3. Pay attention to check seedlings and raise seedlings.

After sowing, check the emergence of wheat in time, and replenish it in time in case of seedling shortage. You can replant and choose the same variety as the seedling-deficient plot. First, the seeds are soaked and germinated at a suitable temperature, and then dried and sown to facilitate the emergence, growth and transplanting.
