Method for making base fertilizer through cow dung treatment

Abstract

The invention relates to a method for making base fertilizer through cow dung treatment. The method comprises the following steps that cow dung is put into a fermentation tank, xylanase and bacillus subtilis are added for stirring, and the fermentation temperature is kept at 26-28 DEG C, wherein the fermentation time is 3-5 days, and the xylanase and the bacillus subtilis account for 6%-8% of thequantity of cow dung; after fermentation is completed, the fermentation temperature is raised to 55-65 DEG C, the increased pressure is 0.4-0.6 Mpa, the sterilization time is 8-12 min, stirring is conducted, the fermentation temperature is raised to 85-105 DEG C, the increased pressure is 1-3 Mpa, and the sterilization time is 2-4 min; sterilized raw materials are spread, cooled and air-dried to achieve the water content being 12%-16%; the dried raw materials are put into a pulverizer for pulvering, wherein the pulvered particles range from 15 mesh to 20 mesh. According to the method for making the base fertilizer through cow dung treatment, the cow dung can be effectively treated, the cow dung can be better mixed into soil in later period, and environmental pollution caused by residues inlater period is avoided.

Description

technical field [0001] The invention relates to the technical field of cow dung treatment, in particular to a method for preparing base fertilizer from cow dung treatment. Background technique [0002] In recent years, with the improvement of people's living standards, the demand for meat is gradually increasing, and the demand for beef is also increasing. Cattle breeding technology has developed rapidly, and cattle breeding has gradually developed in a large-scale and intensive manner. It is also because cattle breeding has obvious advantages in the breeding industry, the market is stable, the risk factor is small, the antibody is strong, there is no spread of the plague disease, and there is no worry about the future. It has become the first choice of the breeding industry, and the benefits are considerable. Gradually increase. With the increase of cattle breeding, there is a large backlog of cow dung in cattle breeding sites, and the treatment of cow dung has become a m...

Problems solved by technology

However, the cow dung has not been effectively treated, so that the cow dung used in the later period is not integrated into the land and is not properly absorbed by the crops. The remaining cow dung also causes the surrounding environment to be polluted.

Moreover, if the bacteria and germs in the cow dung are not completely eliminated, it is easy to breed other small crops, so that the crops planted in the later stage cannot effectively and fully absorb their nutrients, making the crops grow poorly, and the purpose of processing and making base fertilizer cannot be achieved.

In addition, there is no reasonable production of cow dung base fertilizer produced in the later stage, which makes it inconvenient to carry and fertilize, and affects the planting efficiency
