Embodiment Construction

[0033] In order to avoid obstacles such as tillage and fertilization, sowing and emergence of crop stalks or green manure crops caused by plowing or mulching and returning to the field, the inventor proposes a method for crop stalks or green manure crops to be cut and concentrated in trenches and returned to the field, which is characterized in that it includes the following steps :

[0034] (1) digging a landfill ditch in the field and placing the excavated soil on the edge of the landfill ditch;

[0035] (2) cutting down the crop stalks or green manure crops in the field;

[0036] (3) transporting the crop stalks or the green manure crops to the landfill ditch;

[0037] (4) Backfill the excavated soil in the landfill ditch and compact it.

[0038] In the step (1), the width and depth of the buried ditch can be determined as required, preferably, in the step (1), the width of the buried ditch is 20 cm to 30 cm, The depth of the buried ditch is 25 cm to 40 cm.

[0039] In ...

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, ...
