Winter wheat planting techniques

According to its sowing time, wheat is divided into spring wheat and winter wheat. China is mainly winter wheat, and the winter wheat planting areas in China are mainly distributed in Qinling and Huaihe River area. The sowing time of winter wheat is generally from late September to early October, so how to plant winter wheat? Let's take a look at the detailed introduction.

1. Pre-broadcast preparation

Varieties with high yield, stable yield, high yield and strong stress resistance should be selected according to the local climate, soil, diseases and insect pests, such as Zhengmai 9023, E Mai 23, E Mai 18, Huamai 13, and so on. The yield of wheat planting should be done well before sowing, seed coating or chemical dressing should be carried out to reduce the incidence of seedlings, reduce the overwintering pathogenic bacteria and reduce the risk of insect pests. When mixing seeds, the use of chemicals should be strictly used, excessive use of drugs is strictly prohibited, and should be mixed and sown.

2. Soil preparation and fertilization

If it is a corn plot just after harvest, the corn straw can be crushed and returned to the field, spread evenly on the ground, deeply buried in the soil after ploughing, and irrigated steadily after the straw is returned to the field. Base fertilizer can also be applied when straw is returned to the field, and the content of nitrogen, phosphorus and potassium fertilizer should be matched, and attention should be paid to maintaining trace elements, and base fertilizer should be applied according to the yield per mu. Generally, 10-156 kg of nitrogen fertilizer, 4-8 kg of phosphate fertilizer and 4-8 kg of potash fertilizer are used as base fertilizer per mu.

3. Rational sowing

Winter wheat should strictly control the sowing time, sowing too early and too late will lead to lodging in the later stage and affect the yield and quality. The method of strip sowing is generally used when sowing, there are two kinds of strip sowing: equal row spacing or wide and narrow row sowing, sowing should be uniform, the depth should not be too deep and too shallow, and the best depth is 4-5cm. After sowing, we should rake and grind in time and suppress it slightly. In order to ensure the germination rate when sowing, it is best to do the seed germination experiment before sowing, and sow when the seed germination rate reaches 85%.

4. Cultivate strong seedlings

Seedlings should be checked and replenished in time after seed emergence, and if the soil is agglomerated in overcast and rainy weather after emergence, the soil should be loosened in time to increase soil permeability and root growth of seedlings. The frozen water should be better sealed before the soil is frozen, and the watering time should be grasped. At the best time, the average temperature drops by about 3 degrees in the daytime, so that the seedlings can survive the winter safely.
