Problems solved by technology

For example, rice straws are coarsely crushed during harvesting and plowed into the field on the spot, but they often have not rotted after half a year, which affects the growth of crops; therefore, it is urgent to use straws to concentrate on the production of organic fertilizers.

Abstract

The invention discloses a preparation method for converting agricultural waste into an organic fertilizer. According to the present invention, the used raw materials have characteristics of wide source and low price; pathogens, pest eggs and the like can be killed at a high temperature during the preparation; during the fermentation, the cover fermentation is performed with the breath membrane andthe fluid membrane, such that the secondary pollution cannot be generated, and the high activity of the microorganisms required for the fermentation can be ensured; by adding various beneficial floras, a large amount of organic nutrients and organic matters can be supplemented, the soil structure can be improved, the soil pollution caused by fertilizer abuse can be alleviated, and the pests and diseases can be reduced; and the prepared organic fertilizer can be easily absorbed by plants, is harmless to human health, and has great application prospects.

Description

technical field [0001] The invention relates to a preparation method for converting agricultural waste into organic fertilizer. Background technique [0002] Agricultural waste is a general term for waste discharged from agricultural production, agricultural product processing, livestock and poultry breeding and rural residents' life. Agricultural waste is also called agricultural waste. According to its composition, it mainly includes plant fibrous waste and livestock and poultry manure. It is the difference between resource input and output material and energy in the chain of agricultural production and reproduction. The output material energy loss share. [0003] Large-scale livestock farms and places where poultry and livestock are raised on a large scale in house feeding discharge a large amount of manure and the bedding of corrals and poultry houses. If attention is paid to the combination of agriculture and animal husbandry, it can become an important source of organ...
