Process for producing composite biological bacterial fertilizer from livestock and poultry manure

Abstract

The invention discloses a process for producing a composite biological bacterial fertilizer from livestock and poultry manure, which comprises a composite biological bacterial fertilizer process, and the composite biological bacterial fertilizer process is divided into four sections which are first-stage fermentation treatment, second-stage fermentation treatment, third-stage fermentation treatment and fourth-stage fermentation treatment in sequence. A four-stage fermentation technology of different biological beneficial bacteria is adopted, pollution of ammonia gas to the environment is prevented, the lignin is added, the adsorption effect of the lignin on the heavy metal is fully utilized, damage of the heavy metal to soil and crops is avoided, the comprehensive effect of the fertilizer efficiency and the biological effect is achieved, and according to the characteristics and characteristics of existing biological beneficial bacteria, the fertilizer efficiency is improved. Aerobic fermentation and anaerobic fermentation are combined, and through high-temperature fermentation, high-temperature treatment, in-pile culture of an insecticidal fungicide and culture of soil pathogenic bacteria pythium oligandrum, harmless treatment of the livestock and poultry manure is achieved, and damage to crops and soil caused by application of the livestock and poultry manure which is directly or simply treated into the soil is comprehensively avoided.

Description

technical field [0001] The invention relates to the technical field of biological fertilizers for agricultural production, in particular to a process for producing compound biological bacterial fertilizers from livestock and poultry manure. Background technique [0002] Specialized and large-scale breeding of livestock and poultry is the general trend of the development of my country's livestock and poultry industry. In the process of livestock and poultry breeding, the method of feeding feed is often adopted to achieve the purpose of short breeding cycle and high breeding efficiency. Among the feed used for feeding livestock and poultry , contains a variety of heavy metals that balance the nutrition of livestock and poultry. These heavy metals cannot be absorbed and utilized by livestock and poultry, and are excreted in the form of feces. Livestock and poultry feces contain a variety of parasitic pests. They are directly applied to the soil as fertilizer, which not only pollu...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a process for producing compound biological bacterial fertilizer from livestock and poultry manure, which solves the problem that although the prior art has reduced the pathogenic bacteria and parasitic pests in the manure of livestock and poultry to a certain extent, it has no effect on the heavy metals in the manure. Due to the single fermentation bacteria, the ammonia gas in livestock and poultry manure cannot be harmlessly treated, and it will pollute the environment in the early and late stages of fermentation
