How much does it play in wheat before sowing?

How much does the wheat seed mix before sowing:

It has been less than a month since the wheat was planted, and early seed dressing of wheat has begun in Hebei, Shandong, and Henan. At present, wheat seed dressing has become an important part of wheat cultivation. This is not only a guide to cater to national policies, but also farmers' growers can get more benefits. Below, Xiaobian discussed with you, how much does wheat seed dressing before sowing have a high effect on wheat high yield?

1. Reducing the damage caused by wheat pests

The insect pests of wheat can be divided into underground pests and insects on the ground. The underground pests mainly include: cockroaches, golden worms, cockroaches, etc.; the main pests on the ground are: aphids, larvae, and spiders. The underground pests are serious, which will cause wheat seedlings to lack seedlings and ridges, forming weak seedlings and seedlings, affecting the formation of strong seedlings before winter, thus affecting tillering; the above-ground pests are serious, and it is easy to cause wheat to grow normally, grout, and yield. There is direct damage to the formation. Wheat seed dressings generally contain insecticides, which can avoid underground pests and prevent large-scale occurrence of pests on the ground, which plays a key role in wheat.

2. Reduce the damage caused by wheat diseases

China is a country with a large population. The area of ​​cultivated land is small and the multiple cropping index of the land is very high. Therefore, the bacteria in the soil accumulate a lot. It is very easy to endanger the growth of crops when suitable conditions are met, and the impact on yield should not be underestimated. The main diseases of wheat include: sheath blight, total erosion, root rot, smut smut, smut and smut, etc. These diseases have damage to the base of the stem, resulting in poor nutrition supply of the plant. Causes plant death; some damage the ear, directly affecting the formation of grain in the ear. These diseases are serious and can easily lead to reduced production and even the possibility of production. Wheat seed dressings are generally compounded with fungicides, which form a preventive measure from seed sowing, inhibit the infection of pathogens, reduce the occurrence of diseases, and thus increase the yield.

3. Robust plants, enhance stress resistance and increase yield

Whether wheat can achieve high yield, not only control the occurrence of pests and diseases, but also ensure the number of ears per pan and the number of grains per panicle. The seed dressing before sowing can promote growth, accelerate grouting, enhance stress resistance, and form a reasonable number of ears per mu. Number of kernels per spike. Generally high-yield fields, the number of ears per mu should be 40-45 million ears, the number of grains per ear should be 40-50 grains, and the weight of 1000 grains should be 40-45 grams. The wheat seed dressing before sowing can effectively regulate the growth of the plant and ensure the robustness of the plant, thus laying a foundation for increasing production.

4. Prevention is greater than treatment, reducing damage early

Wheat seed dressing before sowing mainly plays a preventive effect. If pests and diseases occur, and then treatment with drugs, this is already causing partial damage. Therefore, the state advocates wheat seed dressing before sowing, and also starts pests from sowing. , a prevention of disease, reduce damage early. The effect of wheat seed dressing before sowing on wheat yield can reach 20%-40% or even higher.
