Embodiment 1

[0019] A method of using crop residues to improve soil, the specific processing method is as follows:

[0020] (1) In the dry field, use the rotary tiller to rotate the fields that need improvement, and dry the fields after rotary tillage for 7-15 days;

[0021] (2) Sprinkle straw powder evenly on the dried fields. Sprinkle 20-25kg of straw powder per mu of field. After the spreading, rotate the tillage again to cover the straw powder and spray water to make the soil surface slightly wet. Yes, dry the field for 3-5 days;

[0022] (3) Sprinkle another layer of modified cottonseed powder on the basis of step (2) after drying the field, cover it with a film for 2-5 days, and then remove the film and rotate it once; by applying cottonseed powder and straw powder It can increase the content of soil organic elements, activate soil microorganisms, increase soil fertility, and can improve soil water absorption and moisture retention capacity, and promote the formation of soil aggregates;

Embodiment 2

[0030] A method of using crop residues to improve soil, the specific processing method is as follows:

[0031] (1) In the dry field, use the rotary tiller to rotate the fields that need improvement, and dry the fields after rotary tillage for 7-15 days;

[0032] (2) Sprinkle straw powder evenly on the dried fields. Sprinkle 20-25kg of straw powder per mu of field. After the spreading, rotate the tillage again to cover the straw powder and spray water to make the soil surface slightly wet. Yes, dry the field for 3-5 days;

[0033] (3) Sprinkle another layer of modified cottonseed powder on the basis of step (2) after drying the field, cover it with a film for 2-5 days, and then remove the film and rotate it once; by applying cottonseed powder and straw powder It can increase the content of soil organic elements, activate soil microorganisms, increase soil fertility, and can improve soil water absorption and moisture retention capacity, and promote the formation of soil aggregates;

Abstract

A method using crops wrack to improve soil comprises the following steps: 1, using a rotocultivator to carry out rotary tillage on the to-be-improved field under a dry field state, and naturally airing the field for 7-15 days after the rotary tillage; 2, evenly spreading straw powders on the aired field, wherein the straw powder amount is 20-25kg per mu, carrying out rotary tillage again after the straw powders are applied so as to cover the straw powders, spraying water so as to micro-wet the soil surface, and airing the field for 3-5 days; 3, spreading an improved cottonseed powder layer after the field is aired in step 2, using a film to cover the field for 2-5 days, removing the film, and carrying out rotary tillage again. The cottonseed powders and straw powders can increase soil organic element content, can activate soil microbes, thus adding soil fertility, improving soil water absorption moisture conservation capability, and promoting soil coacervate formation.

Description

Technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for improving soil by using crop residues. Background technique [0002] Soil is an important component of the geographical environment, as well as the material basis of agricultural production, and the basic resource for the construction of the ecological environment, and is inseparable from the human relationship. However, due to people's unreasonable development and utilization of soil, soil erosion, sandification, desertification, salinization and soil pollution have caused land degradation and soil quality has declined. How to effectively improve poor-quality soil and make full use of limited land resources is a major issue that needs to be urgently resolved in agricultural production, ecological construction and environmental protection. [0003] At present, soil improvement materials in my country mainly include minerals, natural and synthetic polymer materials, a...
