Method for producing biological organic fertilizer by using livestock manure

Abstract

A method for using livestock manure to produce organic fertilizer belongs to the technical field of agriculture and environment sciences. The invention uses livestock manure as raw material and the preparation method comprises mixing and stocking straw powder and aged compost, grafting livestock manure efficient mature bacterial, to complete high-temperature fermentation in short time, thereby realizing harmless and resource recovery, and leading beneficial microbes as phosphorus bacterial, silicate bacterial, photosynthetic bacterial and trichoderma spp or the like into a fermentation system at the later period of fermentation, to obtain biological organic fertilizer. The invention can produce biological organic fertilizer of agriculture planting industry and resolves the pollution of livestock manure.

Description

technical field

[0001] The invention relates to a method for producing bio-organic fertilizer by using livestock and poultry manure, belonging to the technical fields of agricultural science and environmental science. Background technique

[0002] In the late 1980s, my country's livestock and poultry breeding industry has developed rapidly, and the scale, breeding methods and distribution areas of livestock and poultry breeding have undergone tremendous changes. The environmental pollution problems brought about by it have generally increased, intensified and expanded trend. According to the survey conducted by the State Environmental Protection Administration in 2000 on 23 provinces and cities with large-scale livestock and poultry concentration, in 1999, the output of livestock and poultry manure in the mainland of my country was about 1.9 billion tons, accounting for 20% of the annual discharge of industrial solid waste. 2.4 times. At the same time, poultry and livestock ...
