Method for cutting, intensive trenching and returning-to-field of crop straw or green manure crop and associated equipment

Abstract

The invention discloses a method for cutting, intensive trenching and returning-to-field of crop straw or green manure crop. The method includes the steps of (1), digging a back-filling trench in thefield and placing trenched soil at the edge of the back-filling trench; (2), cutting crop straw or green manure crop in the field; (3), conveying the cut crop straw or green manure crop into the back-filling trench; and (4), filling the trenched soil back to the back-filling trench while compacting the soil. The invention further provides associated equipment for implementing the method. The method is unique and novel, can realize improvement of soil fertility through returning-to-field of crop straw or green manure crop, can also overcome troubles in tillage, fertilizer applying, seeding, germinating and the like due to returning-to-field of crop straw or green manure crop by turning or covering; the associated equipment is of skillful design, easy and convenient to operate, low in cost and suitable for promotion and application in large scale.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to the technical field of returning crop straws and green manure crops to the field, and specifically refers to a method for crop straws or green manure crops to be cut and concentrated to be buried in trenches and returned to the field and related equipment. Background technique [0002] Returning crop stalks and green manure crops is an effective way to fertilize soil fertility, and most of the returning methods are plowing or mulching. [0003] However, with the impact of crop yield level and continuous returning to the field, more crop residues will be accumulated per unit area. Returning high-yield crop straws to the field in full will often increase the operating costs and energy consumption of subsequent crops in terms of site preparation, sowing, emergence, and seedling establishment; the depth of burial of straw is not enough, and the quality of turning over is poor, ...

[0003] However, with the impact of crop yield level and continuous returning to the field, more crop residues will be accumulated per unit area

Returning high-yield crop straws to the field in full will often increase the operating costs and energy consumption of subsequent crops in terms of site preparation, sowing, emergence, and seedling establishment; the depth of burial of straw is not enough, and the quality of turning over is poor, and a large amount of straw accumulates in the plow layer, which is not conducive to the topsoil Cultivation; straw returning to the field has a certain potential for carbon sequestration, but the methane emission increase benefits of paddy fields offset the carbon sequestration benefits and increase greenhouse gas emissions; in addition, the release of toxic substances produced by straw returning to the field and decomposing concentrated on the soil surface often inhibits the growth of seedlings. growth and absorption of nutrients, and even cause yield reduction
