Problems solved by technology

[0002] With the changes in production and life, most of the straw is returned to the field before sowing and land preparation, which can improve the soil structure and increase soil organic matter. However, at present, many farmers only pursue the straw returning to the field, and the straw is not treated after returning to the field, and the straw decomposes slowly. , the cycle is long, it will also lead to the increase of soil pathogens and crop diseases, which will affect the quality of sowing and crop growth and yield. The gap is large, which seriously affects the quality of sowing and the decomposition and maturity of straw

Embodiment Construction

[0014] The content of the present invention will be described below in conjunction with specific embodiments.

[0015] A method for returning decomposed straw to the field, the method for returning the decomposed straw to the field comprises the following steps:

[0016] (1) Straw treatment: collect straw, put it in the sun to dry, it is not easy to rot and rot, crush it with a pulverizer, it is easy to spread, and the crushing amount of straw returned to the field per mu is ≤500 kg, otherwise, it will affect the straw in the soil. Decomposition rate and crop yield;

[0017] (2) Apply decomposing agent: mix 2 kg of decomposing agent and 5-10 kg of urea per mu evenly, and then spread it on the crushed straw. Nitrogen, to avoid competition between decomposing bacteria and crops for nitrogen, applying 5-10 kg of urea can maintain carbon and nitrogen balance;

[0018] (3) Soil preparation and decomposing: Spread the straws applied with decomposing agent evenly on the field. Unev...

Abstract

The invention discloses a straws decomposition and returning method. The method comprises the following steps: processing straws, applying a decomposition agent and performing site preparation for decomposing. The method is characterized in that the straws are crushed, the decomposition agent and the urea are added, decomposition temperature is increased, straw decomposition speed is accelerated, fermentation period is shortened, enough microbe and energy can be provided for straws decomposition, good soil constitution can be created after site preparation for decomposing, factors of moisture, nutrient, air and heat can be coordinated, water storage and fertilizer conservation capabilities of the soil can be increased, and the crop growth quality and output can be obviously increased.

Description

technical field [0001] The invention belongs to the field of crop stalk utilization, and relates to a technical method for resource utilization of straw wastes, in particular to a method for returning decomposed straw to the field. Background technique [0002] With the changes in production and life, most of the straw is returned to the field before sowing and land preparation, which can improve the soil structure and increase soil organic matter. However, at present, many farmers only pursue the straw returning to the field, and the straw is not treated after returning to the field, and the straw decomposes slowly. , the cycle is long, it will also lead to the increase of soil pathogens and crop diseases, which will affect the quality of sowing and crop growth and yield. Large gaps will seriously affect the quality of sowing and the decomposition and maturity of straw. Contents of the invention [0003] The object of the present invention is to provide a method for retu...
