What techniques are needed to grow wheat in Yicheng District, Mashi City, Henan Province?

Wheat 1 High-yield Cultivation Techniques, Scientific Soil Preparation

You don't need much soil to grow wheat. In order to ensure the application effect of high-yield cultivation techniques to achieve the expected effect, it is necessary to intensively cultivate the soil to improve the output value. If straw is returned to the field for planting soil, the soil should be deeply ploughed with a deep plough before sowing to break the soil hardening, and the depth should be controlled at 25? Above cm. After deep ploughing, harrow at least two places to improve the permeability of the soil, ensure that the soil layer is empty and solid, with good water and fertilizer conservation performance, and at the same time, the ground is flat and the irrigation and drainage conditions are good? .

Step 2 Apply base fertilizer

To ensure the high yield of wheat planting, it is necessary to apply sufficient base fertilizer to lay the foundation for high yield of wheat. The production level of wheat is closely related to soil fertility. If soil nutrients and fertility are insufficient, it is difficult to ensure high and stable yield of wheat. Regional agricultural production should focus on improving soil fertility, scientifically and rationally apply fertilizers in strict accordance with the requirements of soil testing formula, and ensure that the soil organic matter content is above 2.8, the total nitrogen content is 0. 15%, and the phosphorus and potassium fertilizers are kept at? 33? Mg/kg? And then what? 195? Mg/kg? To sum up, it can meet the nutritional needs of wheat at all growth stages.

In addition, after the previous crop is harvested, the total amount of straw should be returned to the field as much as possible. Crush the straw into? 10? Cm, adding the corresponding straw decomposing agent in the field, and mixing at least? 20? kg？ Moisten fine soil, ensure the effect of returning straw to the field, improve the content of soil organic matter and ensure the normal growth of wheat.

3. Variety selection and seed treatment

(1) variety selection

Wheat varieties are closely related to high and stable yield. According to the local natural environment and climatic conditions, select wheat varieties with good disease resistance, strong environmental adaptability and high yield, such as Xinong 10 18, Zhumai 305, etc.

(2) seed treatment

First, dry the seeds for at least 3 days to ensure that the seeds have good water absorption capacity. Moreover, sunlight can also destroy pathogenic microorganisms on the surface of seeds and improve the germination survival rate. According to the requirements of regional green planting, imidacloprid or dividan can be used for seed dressing to improve the disease resistance of wheat, reduce the occurrence of pests and diseases, and lay the foundation for high and stable yield. In addition, sunny weather should be chosen when sowing, and inferior seeds should be screened by seed selection machinery before sowing, which can improve the purity of seeds and is conducive to cultivating strong seedlings.
