Method for bio-converting cow breeding excrement slurry waste liquid and compounding synergistic fertilizer by combining earthworms with edible fungus dregs

Abstract

The invention relates to the technical field of resourceful treatment of livestock and poultry excrement wastes, in particular to a method for bio-converting cow breeding excrement slurry waste liquidand compounding a synergistic fertilizer by combining earthworms with edible fungus dregs. The method comprises the following steps: carrying out solid-liquid separation on cow excrements and separately fermenting the cow excrements; composting an earthworm breeding bed by using fungus dregs and the fermented and decomposed cow excrements obtained after solid-liquid separation; irrigating the breeding bed with the fermented excrement slurry waste liquid, and inoculating earthworm cocoons mixed with earthworm excrement on the earthworm bed; when the earthworm cocoons are hatched and juvenile earthworms start to grow and eat a treated substrate, irrigating with the excrement slurry waste liquid timely; and timely collecting high-quality earthworm excrement in batches from the upper surfacelayer, and compounding the collected high-quality earthworm excrement with biological carbon to obtain the synergistic fertilizer. According to the method, liquid slurry excrement pollution and the edible fungus stick waste pollution generated in the cow breeding industry can be bio-converted, water used in the earthworm breeding link is saved, the excrement waste liquid of the cow breeding industry is functionalized and converted into resources, and the produced flowering-promoting peony substrate synergistic fertilizer can obviously improve the comprehensive quality of flowering-promoting peonies.

Description

technical field [0001] The invention relates to the technical field of resource treatment of livestock and poultry manure waste, in particular to a method for bioconverting dairy cow breeding manure slurry and waste liquid by combining earthworms with edible fungus residue and compounding a synergistic fertilizer. Background technique [0002] The dairy farming industry in my country is developing very fast, and the total contribution rate to the total agricultural output value is also increasing year by year. Large-scale centralized breeding of dairy cows improves the breeding level and production performance, reduces feeding costs and increases economic benefits, but also causes concentration of manure and washing water. The increasing amount and the increasingly serious pollution of the ecological environment. Dairy cows in the lactating period of the dairy farm produce about 30kg of manure per cow per day, about 15kg of urine, and the average water content of manure is ab...

Problems solved by technology

Due to the use of dormancy-breaking techniques such as airing the roots, it is difficult to root the Spring Festival flower peonies, resulting in the current situation that the Spring Festival flower peonies generally have low quality and poor stress resistance.

High-quality vermicompost has a good effect of promoting rooting, but it is common in production that the amount of vermicompost must reach 20% to achieve a good effect. Therefore, the technology of vermicompost function amplification needs to be solved urgently
