When is the best winter irrigation time for wheat?
In China, wheat planting areas include northern Anhui, Henan, Shaanxi, Shandong, Hebei, Jiangsu and other provinces dominated by wheat, and Jiangsu Province is the most suitable province for winter irrigation. Winter irrigation of wheat can prevent and control seedling death in a balanced and stable way, increase soil moisture, store it in winter and use it in spring, prevent seedling death in spring, help to package and strengthen seedling tillering, effectively kill pests and create favorable conditions for wheat to turn green in the coming year.
Before winter irrigation, we must look at the situation of wheat fields, and the field water holding capacity should not be lower than 80%. Wheat fields with water irrigation conditions should be watered, and seedling conditions should be considered before watering. The tillering ratio per plant is more than 1.5-2 wheat field, so winter irrigation is more suitable. Never water weak seedlings and single seedlings, or freeze injury will easily occur.
Wheat is introduced in detail as follows:
Wheat is the general name of the genus Triticum, and the representative species is common wheat, which is a gramineous plant and a cereal crop, and is widely planted all over the world. Wheat caryopsis is one of the staple foods of human beings. After grinding into flour, it can be made into bread, steamed bread, biscuits, noodles and other foods. After fermentation, it can be made into beer, alcohol, liquor or biomass fuel. In 2022, the national wheat output was 276,543.8+0.52 billion Jin.
Wheat is one of the three major cereals, almost all of which are used for food, and only about one-sixth of which are used as feed. The two river basins are the earliest areas to cultivate wheat in the world, and China is one of the earliest countries to cultivate wheat in the world.
