Stub-leaving no-tillage spring-manure wheat sowing and cultivation method

Abstract

The invention relates to a sowing technique, in particular to a stub-leaving no-tillage mechanical sowing cultivation method. The stub-leaving no-tillage mechanical spring-manure wheat sowing cultivation method comprises the steps of harvesting wheat, irrigating in winter, performing medical treatment on selected spring-manure wheat seeds, mixing the selected spring-manure wheat seeds with chemical fertilizer, performing stub-leaving no-tillage mechanical spring-manure wheat sowing, performing field management of stub-leaving no-tillage spring-manure wheat, and performing stub-leaving no-tillage spring-manure wheat harvesting and the like. The method has the advantages of increasing moisture in soil, reducing wind corrosion and waster and soil loss, regulating ground temperature, increasing nutrients in soil, improving activity of soil enzymes and the like.

Description

technical field [0001] The invention relates to a sowing technology, in particular to a sowing and cultivation method of a stubble no-tillage machine. Background technique [0002] Crop straw is one of the most abundant renewable resources in agricultural production. The northern wheat planting area in my country is rich in crop straw, but the straw utilization technology in this area is backward, the resource conversion rate is low, and the problems such as insufficient recycling are prominent. In recent years, due to the replacement of livestock by agricultural mechanization, coal and liquefied gas instead of straw as fuel, and the difficulty of stubble removal by combine harvesters, straw burning has become very common. The wheat planting area in the north of our country has little rainfall, with an annual rainfall of 36-160 mm. The straw is returned to the field and turned into the ground, which is not easy to rot. In order not to affect the plowing and sowing of the ne...

Problems solved by technology

Straw burning not only causes environmental pollution, but also reduces the activity of microorganisms on the soil surface (Ruiji Yang, Hailing Ma, Qifeng Yang, et al. Effects of planting density and nitrogen application rate on soil microbial activity of rape as fodder for multiple cropping with wheat stubble. Journal of Applied Ecology, 2007, 18(1) :113-117.)

At the same time, the soil surface is exposed in spring and winter, which is easy to form surface runoff and soil erosion, leading to the deterioration of the ecological environment (Luo Zhuzhu, Huang Gaobao, Xin Ping, et al. Comparative analysis of surface soil structure and organic carbon content of different conservation tillage methods in Longzhong dryland . Agricultural Research in Arid Areas, 2008, 26(4): 53-58.)
