What is the depth standard of wheat sowing? How to effectively avoid sowing too deep? How to effectively avoid sowing too deep? Wheat has a long growth period and well-developed roots, so it is necessary to cultivate deeply and carefully. The sowing depth of wheat should be determined according to the actual situation, and the sowing should not be too shallow or too deep. If the sowing is too shallow, it is easy to have incomplete seedlings, leading to lack of seedlings and broken ridges. Sowing too deep, the seedlings grow thin and weak, and there are few tillers, so the tillering seedlings grow weak. 1, soil properties. Sandy loam has good air permeability, poor water retention and rapid water loss, which is suitable for deep sowing, and the sowing depth is 4-5 cm. Cohesive soil has poor air permeability and good water retention, and is suitable for shallow sowing. The sowing depth is 3-4 cm. 2. Soil moisture. If the soil moisture is poor, it is better to sow deeply to prevent the buds from drying, and generally it is better to sow deeply about 5 cm. If the soil moisture is good, shallow sowing should be carried out, and the sowing depth is generally 2-4 cm. 3. sowing date. Early sowing temperature is high, seedling emergence is fast, but soil moisture is also fast, so deep sowing can be carried out, late sowing temperature is low, seedling emergence is slow, and shallow sowing is suitable.

When planting wheat, the depth of tractor cultivated land is 20-25 cm. There is a saying in agriculture that when sowing, the depth of deep ploughing seedlings is 5-7 cm, which makes it difficult for wheat to germinate in deep soil. If the sowing is shallow, I am afraid that the wheat will not germinate because of drought. We must master a certain humidity of the land, as long as the planting of wheat is not less than 10 cm. When the ground temperature is kept at 5cm, wheat will germinate, settle down, take root quickly, be strong and flourish. Winter wheat should be planted deep and shallow. Why do you want to broadcast shallowly?

Deep sowing, cool soil, weak seedlings, easy to reduce production. Wheat is not easy to sow too deep, and the best depth is 3 to 5 cm, as long as it can germinate. Some people say that seedlings planted shallow are afraid of drought. On the contrary, they will be thick and dark green when they come out, because the soil 3/5cm deep is hot and the roots will not die if they are rooted in the soil. Why do you say that your wheat, seeds, fertilizers and field management are the same as others, but they are not high-yielding? The reason for the low yield of wheat is deep sowing. . .
