First, increase organic manure. Compost, manure, cake fertilizer, manure, manure, manure, rivers and lakes are all good organic fertilizers.
Second, promote the return of straw. Studies have shown that the direct return of straw to the field is more effective than the application of an equal amount of alfalfa. At present, northern China is vigorously advocating wheat straw sorghum as the main measure to return straw to the field. When wheat is harvested, leave 20 to 30 centimeters of high wheat straw. After a rainy season, the wind is blowing in the sun and rain, and when wheat is sown, Has become a semi-decomposing state, becoming a good organic fertilizer. The return of straw to the field is simple and easy, labor-saving and labor-saving, but when returning to the field, chemical nitrogen fertilizer should be added to avoid microbial competition with the crop.
Third, grain and fertilizer rotation, intercropping, combined with land use. With the development of agricultural production, the multiple cropping index is getting higher and higher, causing many soil organic matter content to decrease and fertility to decline. Implementing a system of grain and fertilizer rotation and intercropping can not only maintain and increase the content of organic matter, but also improve the quality of soil organic matter and activate the aging humus.
Fourth, cultivation of green manure. Cultivation of green manure can provide rich organic matter and nitrogen for the soil, improve the agricultural ecological environment and physical and chemical properties of the soil. The main varieties are: gardenia, wolfberry, mung bean, Sesbania etc. Scorpions are generally sown in early September and used as a base fertilizer and leave seed for spring crops. They can also be sown in March and April for dressing. The sowing rate is 3~5 kg/mu and the buds can be pressed in the second year of April. Cockroaches can be planted in spring, summer and autumn, generally 1 to 1.5 kilograms per acre, and greening at full bloom. Mungbean and Sesbania can be sowed in 3~6 months, generally 3~5kg per mu, pressing green at the beginning of flowering period.
