Livestock and poultry feces organic fertilizer fermentation compound functional package and preparation method and application thereof

Abstract

The invention discloses a livestock and poultry feces organic fertilizer fermentation compound functional package, which comprises a compound functional package A and / or a compound functional packageB. The compound functional package A comprises a compound microbial agent, a compound enzyme preparation, humic acid, white spirit vinasse powder and zeolite powder; the compound functional package Bcomprises isomaltooligosaccharide, molasses meal, monopotassium phosphate, magnesium sulfate, ferrous bisglycinate, manganese bisglycinate, bamboo vinegar powder and citric acid. The package A and thepackage B are combined, the fermentation speed can be greatly increased, quick heating deodorization and thorough decomposition can also be achieved in the low-temperature season, diseases and insect pests and antibiotic residues can be effectively removed, the quality is stable, the quality guarantee period is long, and practicability is high. The invention further discloses a preparation method and application of the compound functional package, the compound functional package is used for livestock and poultry feces organic fertilizer fermentation, the harmless treatment efficiency is high, resource utilization is high, an obtained organic fertilizer product is high in functionality and comprehensive in nutrition, and has no toxicity, stink, harm and pollution, and the organic fertilizer use standard requirement is met.

Description

technical field [0001] The invention belongs to the field of organic fertilizers, and in particular relates to a compound functional package for fermentation of livestock and poultry manure organic fertilizers and its preparation method and application. Background technique [0002] According to statistics, my country produces about 3.8 billion tons of livestock and poultry manure every year, of which the annual production of pig manure is about 1.8 billion tons, accounting for 47% of the total; 37%, including 400 million tons of dairy cows and 1 billion tons of beef cattle; the annual production of poultry manure is about 600 million tons, accounting for 16% of the total. These manures have become the main source of agricultural non-point source pollution. The Bulletin of the First National Survey of Pollution Sources shows that the chemical oxygen demand discharged by my country's livestock and poultry farming industry reached 12.6826 million tons, accounting for 96% of th...

AI Technical Summary

Problems solved by technology

[0004] During the current fermentation process of livestock and poultry manure into organic fertilizer, due to the generally high water content of livestock and poultry manure, there are a large number of harmful pathogens such as Escherichia coli, Salmonella, Shigella, roundworm eggs, nematodes, cellulose, hemicellulose , lignin and other refractory substances, serious odor pollution, antibiotics (such as: oxytetracycline, tetracycline, chlortetracycline, doxycycline, etc.) and heavy metal residues, and different types of breeding animals (such as: sows, Small pigs, medium and large pigs, egg poultry, meat poultry, cattle and sheep, etc.) have different manure components and harmful substances, adding a single fermentation decomposing agent for fermentation treatment often has slow fermentation temperature rise, long cycle, difficult loss of water, and incomplete decomposition , low utilization rate of resources and long duration of odor, etc., especially in low temperature season

This leads to problems such as high moisture content of the produced organic fertilizer, insufficient fermentation maturity, low fertilizer efficiency, incomplete killing of pathogenic bacteria and insect eggs, antibiotic residues and odor, etc. After being applied to the soil and continuing to ferment and decompose, harmful gases such as methane and ammonia will be produced. It pollutes the environment, breeds a large number of mosquitoes and flies, affects the quality and use effect of organic fertilizers, and even causes food safety problems such as burning roots and seedlings of planted crops, pests and diseases, and antibiotic residues
