No-tillage direct seeding and mulching cultivation method of rice

Abstract

The invention provides a no-tillage direct seeding and mulching cultivation method of rice in the technical field of agricultural planting. In the cultivation method, Chinese milk vetch serves as green manure in winter, and is mulched on the ground surface as organic green manure before the seeding of the rice; and all rice straws are returned to the field, and are mulched on the ground surface after the rice is harvested; therefore, the permanent no-tillage of a rice field and the direct seeding of the rice are put into practice, and thus the crop rotation of the rice and the green manure are put into practice. When the method is adopted, the growth and development of soil organisms are improved; the diversity of the soil organisms is enriched; the application of fertilizers is reduced; the widespread pollution of a farming land is reduced; labor and force are saved; the agricultural planting efficiency is improved; and the quality of the rice is improved.

Description

technical field [0001] The invention relates to a method in the technical field of agricultural planting, in particular to a no-tillage direct seeding and covering cultivation method for rice. Background technique [0002] The core problem of sustainable utilization of cultivated soil in my country is the depletion and deterioration of soil organic matter, which directly leads to the decline of soil function. Soil organic matter is the basic material of the soil system, which affects the physical and chemical properties of the soil, and controls microbial activity through the C and N sources provided, thus playing an important role in soil fertility. Good soil physics, chemistry and biology The properties, as well as the productivity of soil, are closely related to the content and characteristics of soil organic matter. Due to the lack of organic matter, the cycle conversion and utilization rate of various nutrients are low, the soil ecosystem is out of balance, and the soi...

However, this method requires paddy tillage, without returning rice stalks to the field, and the rice cannot be sown, which is not conducive to soil and water conservation and the development of soil biodiversity.
