Problems solved by technology

However, traditional composting has problems such as small number of functional microorganisms, long fermentation cycle, low degree of decomposing, large odor pollution, and serious loss of fertilizer efficiency.
While endangering the environment and human and animal health, it also reduces the fertilizer efficiency and agricultural value of compost

Abstract

The invention discloses a method for preparing an organic fertilizer by fermenting chicken manure by using compound bacteria. The method comprises the steps: mixing chicken manure, crop straw powder and a compound bacterium fermenting agent to obtain a mixture; controlling the water content of the mixture at 45%-55%, meanwhile, spraying a fermentation liquid on the mixture by using a sprayer, andcarrying out fermentation treatment; after fermenting the chicken manure, carrying out composting; delivering the chicken manure into a curing warehouse, stacking the chicken manure to form a conicalmanure pile with the height of 2-3m, and carrying out low-temperature drying at room temperature; and adding the chicken manure into a mixer for mixing, and then, carrying out granulation in a granulator to prepare an organic granulated fertilizer. The method has the advantages that the method is simple, the fertilizer efficiency can be increased, the environment can be protected, the ecological balance of microorganisms in soil can be effectively reduced, and straws and the chicken manure can eliminate soil hardening, improve the permeability of the soil and reduce the residues of chemical substances in the soil.

Description

technical field [0001] The invention relates to a method for preparing organic fertilizer by fermenting chicken manure with compound bacteria. Background technique [0002] In 24 provinces across the country, the discharge of chemical oxygen demand from livestock and poultry farms and specialized breeding households accounted for more than 90% of the total local agricultural non-point source discharge. In recent years, the total amount of livestock and poultry breeding in my country has continued to increase, producing 3.8 billion tons of livestock and poultry manure every year, but the effective treatment rate is less than 30%. With the increasing scale of chicken farms and the increasing degree of intensification, the large amount of excrement produced by the breeding industry is also increasing, which brings great pressure to environmental sanitation. [0003] Composting is currently an effective method for harmless, resourceful, and fermentative treatment of chicken man...
