Method for producing organic fertilizer by utilizing fermentation packing in cage culture layer house

Abstract

The invention discloses a method for producing an organic fertilizer by utilizing a fermentation packing in a cage culture layer house. The method comprises the following step: evenly mixing dried sawdust, dried rice husk, fresh chicken mature and water containing fermentation strains, and piling together for pilling fermentation; then transporting the fermented fermentation packing in the cage culture layer house so as to carry out groove type aerobic fermentation for 1.5-3 months; and clearing the fermented material out of the layer house and then carrying out the pilling fermentation again, after the pilling fermentation, airing the material until the content of water is less than or equal to 20% so as to obtain the organic fertilizer product. Through using the method, the efficient organic fertilizer can be produced, the environment in the layer house is improved, and simultaneously a series of difficultly treated problems, such as clearing, transportation, hazard-free treatment and the like, are solved. The method is ecological and environmentally-friendly, fully meets the requirement of sustainable development of aviculture, and has wide development prospects.

Description

technical field [0001] The invention relates to a method for producing organic fertilizer by using the fermented litter of caged laying hens. Background technique [0002] In recent years, the rapid growth of the number of caged laying hens in my country has made an important contribution to meet the national demand and ensure the supply of poultry eggs. However, with the increase in the number of caged laying hens, the pollution of laying hens is becoming more and more serious. Especially in summer, the ambient temperature is high, the water content of chicken manure is high, and the gas in the chicken house, especially ammonia, is more polluted. These harmful gases are harmful to the environment. Harmful to humans and poultry. Although manual or mechanical manure removal in the laying hen house can handle the manure, it is labor-intensive, and the chicken manure liquefies rapidly after being cleared from the hen house, so it cannot be collected and transported in a centra...

AI Technical Summary

Problems solved by technology

However, with the increase in the number of caged laying hens, the pollution of laying hens is becoming more and more serious, especially in summer, when the ambient temperature is high, the water content of chicken manure is high, and the gas in the chicken house, especially ammonia, is more polluted. These harmful gases are harmful to the environment. Harmful to humans and poultry

Although manual or mechanical manure removal in the layer house can handle the manure, it is labor intensive, and the chicken manure liquefies quickly after being cleared from the hen house, so it cannot be collected and transported in a centralized manner

The cleared chicken manure not only takes up a lot of site space, has a bad smell, but also breeds a lot of bacteria and mosquitoes, seriously polluting the surrounding environment, and at the same time, transporting from the chicken house to the fermentation place increases the transportation cost

In addition, due to the high water content of chicken manure in summer, especially from July to September, the chicken manure is in the form of thin soup and has a serious stench, so it cannot be transported out to make fertilizer.
