Embodiment Construction

[0013] A method for intensively plowing and returning rice and wheat straw to the field, comprising the following steps:

[0014] (1) Concentrated sorting of rice and wheat straw: When harvesting rice or wheat, crush the rice straw or wheat straw, and sort the straw into a width of about 50 cm at intervals of 300 cm to 400 cm, so that the field is 300 cm to 400 cm wide. Alternate distribution of 400 cm open area (no straw coverage area) and 50 cm straw belt (straw concentrated composting area);

[0015] (2) Deep plowing and returning of rice and wheat straw to the field: Deep plowing is carried out on the straw belt with a deep plow, and the plowing depth is ≥30cm; plowing and deep burying of rice straw or wheat straw;

[0016] (3) Shallow plowing and leveling of the soil: shallow plowing and harrowing of the soil, with a depth of 8-12cm, and leveling of the soil by means of shallow rotation or shallow harrowing;

[0017] (4) Sowing and planting of rice and wheat: sow or plan...

Abstract

The invention discloses a centralized ploughing and burying returning method of rice and wheat straw. The method includes the steps of rice and wheat straw centralized arrangement, rice and wheat straw deep ploughing and returning to field, soil shallow ploughing and leveling, rice and wheat sowing and planting, field management and the like. According to the method, root layer soil of rice and wheat can have high fertility, tiller strengthening, early sprouting and high-yield promotion are facilitated, mechanical operation of management links like straw arrangement and centralized ploughing and burying, sowing (planting), field plant protection and fertilizer application can be achieved, an empty zone is especially reserved for a mechanical operation way, and full-process mechanical production of rice and wheat after farmland scale operation is better facilitated.

Description

technical field [0001] The invention relates to a method for intensively burying and returning rice and wheat straw to the field. Background technique [0002] For a long time, the constant pursuit of high crop yields has been the relentless pursuit of many agricultural scientists. How to improve soil fertility and achieve high crop yields requires continuous research and exploration by agricultural scientists; conventional cultivation methods need further improvement. Contents of the invention [0003] The object of the present invention is to provide a method for intensively burying and returning rice and wheat straw to the field for improving soil fertility and realizing high crop yield. [0004] Technical solution of the present invention is: [0005] A method for intensively burying and returning rice and wheat straw to the field is characterized in that it includes the following steps: [0006] (1) Concentrated sorting of rice and wheat straw: When harvesting rice ...
