Method for producing bio-organic fertilizer by utilizing livestock and poultry feces

Abstract

The invention relates to the technical fields of agricultural science and environmental science, and discloses a method for producing a bio-organic fertilizer by utilizing livestock and poultry feces, which is characterized by comprising the following steps of: crushing stalks and coal ash and sieving by using a sieve of 15 to 40 meshes; uniformly mixing the livestock and poultry feces, stalk powder, coal ash, humid acid and a composite solid strain according to a ratio of (350-400): (15-18): (25-28): (40-45): (1-2) by using a premixer; putting into a special fermentation tank, fermenting at normal temperature for 20 to 30 days, controlling the temperature in the fermentation tank in the fermentation process to be 55-75DEG C, and simultaneously performing proper stirring and full aeration; taking the fermented materials out, drying, sieving, and granulating into powder. The livestock and poultry feces are taken as main raw materials, so the method is simple in process, easy to operate and low in product cost, and has obvious economic and social benefits.

Description

technical field [0001] The invention relates to the technical fields of agricultural science and environmental science, in particular to a method for producing bio-organic fertilizer by using livestock and poultry manure. Background technique [0002] At present, there are two main types of fertilizers applied to crops, one is farm manure and the other is chemical fertilizer. Farmyard manure plays a certain role in improving soil, increasing fertility and crop yield, but its disadvantages are low nutrient content, not strong quick-acting, containing pathogenic bacteria, parasites, weed seeds, polluting soil and atmosphere, more prominent It is impossible to organize large-scale commercial production and enter the field of circulation. Although chemical fertilizers have high nutrient content and fast-acting fertilizer application, their shortcomings are obviously exposed with the large-scale application of chemical fertilizers, which cause soil compaction, acid-base imbalanc...

AI Technical Summary

Problems solved by technology

[0003] With the rapid expansion of my country's livestock and poultry breeding industry, a large number of large, medium and small livestock and poultry farms have been built around cities and in vast rural areas, and some areas have also established professional livestock and poultry breeding communities, professional villages, and professional households. A large amount of livestock and poultry manure is produced. Because no comprehensive treatment measures are taken, the livestock and poultry manure is discharged into the natural environment without any treatment. At the same time, it is easy to cause the prevalence of infectious diseases such as bird flu, and bring harm to people's health
