A recycling method of using agricultural waste to convert pig excrement and urine without external emission of pollution

Abstract

The invention provides a recycling method of using agricultural waste to convert pig excrement and urine without external emission of pollution and particularly provides a method of raising pigs. The method comprises the steps of firstly crushing herbal agricultural waste into powdery scraps and segmented scraps and mixing the scraps to obtain a fermentation raw material; secondly, mixing the fermentation raw material and pig excrement and urine and zymophyte agents to obtain a fermentation starting material; thirdly allowing the fermentation starting material to perform aerobic fermentation under a ventilation condition and allowing the aerobic fermentation product to perform oxygen-limited fermentation under a closed condition to obtain an oxygen-limited fermentation product; fourthly using the oxygen-limited fermentation product as pigsty padding and raising pigs on the padding. With the technical solution, the method can prevent external emission of pollution of pig excrement and urine of large-scale pig raising by using herbal agricultural waste without using woody materials such as bits of wood and mushroom dregs.

Description

technical field [0001] The present invention relates to the field of agricultural biotechnology, specifically to the field of livestock and poultry breeding and environmental technology, more specifically to a method for recycling pig manure and urine from agricultural waste that is polluted without efflux, and more specifically to a breeding method The hog method. Background technique [0002] With the development of large-scale pig farming, the environmental pollution caused by livestock and poultry manure has become increasingly prominent. Therefore, the technology of pig farming in fermentation beds has been paid more and more attention. The source of raw materials has become a restrictive factor restricting the promotion of fermentation bed technology. [0003] Fermentation bed pig raising technology is an advanced breeding mode that originated in Japan and South Korea, and then began to rise in China. It is based on microecological theory and biological fermentation t...

Problems solved by technology

At present, there is a technology of mixing fresh wood chips and / or fungal residues with herbal agricultural wastes and then fermenting them as bedding materials. The degradation rate of pig manure and urine is low, which will cause the accumulation of pig manure and urine, the growth of pathogenic bacteria, environmental pollution and other problems, and it is difficult to meet the needs of degrading pig manure during pig breeding
