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

Embodiment 1

[0035] (1) Mushroom residue preparation: collect discarded mushroom sticks after cultivation of edible fungi by large-scale edible fungus enterprises, remove the outer layer of polyethylene plastic packaging bag of edible mushroom sticks, air-dry, crush and serve as edible fungus residue, and the particle diameter of the mushroom residue is 0.5~2cm , so that the water content is controlled at 8% to 15%.

[0036] (2) Establishment of the anaerobic pond: the size of the anaerobic pond is determined according to the number of cows, and it is advisable to at least meet the storage of waste liquid for 30-50 days. The designed anaerobic pond has an aspect ratio of 2:1 and a depth of 3.5m , Set the water outlet and the water inlet on the anaerobic pond, and the distance between the water outlet and the water inlet is greater than 50 meters, so that the waste liquid can fully anaerobically ferment.

[0037] (3) Solid-liquid separation of cow manure: use the wastewater from the outlet ...

Abstract

The invention relates to the technical field of resource treatment of livestock and poultry manure waste, in particular to a method of bioconverting milk cow breeding manure waste liquid and compounding synergistic fertilizer with earthworms combined with edible fungus residue, and separating milk cow manure from solid and liquid and fermenting it separately The earthworm breeding bed is made of fungus residue and decomposed cow dung fermented after solid-liquid separation, and the breeding bed is irrigated with the fermented dung slurry waste liquid, and the earthworm bed is inoculated with vermicompost mixed with vermicompost. After the cocoon is hatched and the young worm When starting to grow and feed on the treatment substrate, water the manure slurry and waste liquid at the right time, and start collecting high-quality vermicompost in batches from the upper surface at the right time, and compound it with biochar to obtain a synergistic fertilizer. The present invention can biotransform liquid pulpy feces pollution and edible fungus stick waste pollution produced in the dairy cow breeding industry, save water in the earthworm breeding process, make the feces and waste liquid of the dairy cow breeding industry functional and resource-based, and increase the matrix of the flower-promoting tree peony produced. Effective fertilizer can significantly improve the comprehensive quality of peony.

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...
