Embodiment 1

[0013] Embodiment 1: the production technology of fermented organic fertilizer of laying hen manure in the south, comprises the steps:

[0014] (1) Mix fresh free-range dry chicken manure with a water content of about 12% and fresh caged chicken manure with a water content of more than 90% evenly to prepare chicken manure with a water content of 60%-70% for later use. Wherein, the amount of free-range dry chicken manure and cage-raised dilute chicken manure is based on the mixture of chicken manure with a water content of 60%-70%;

[0015] (2) Initial fermentation: Add zeolite powder and calcium chloride to chicken manure with a water content of 60%-70%, and the weight of chicken manure, zeolite powder and calcium chloride with a water content of 60%-70% The ratio is 100:3:3, and the rw fermentation agent is added, stirred and mixed evenly, and then fermented at a temperature of 70°C for about 10 days to obtain the initial fermentation material; the rw fermentation agent is pu...

Embodiment 2

[0017] Embodiment 2: the production technology of fermented organic fertilizer of laying hen manure in the south, comprises the steps:

[0018] (1) Mix fresh free-range dry chicken manure with a water content of about 12% and cage-raised thin chicken manure with a water content of more than 90% to prepare chicken manure with a water content of 60%-70% for later use. The amount of free-range dry chicken manure and cage-raised dilute chicken manure is based on the chicken manure with a moisture content of 60%-70%;

[0019] (2) Initial fermentation: Add zeolite powder and calcium chloride to fresh chicken manure with a water content of 60%-70%, and the mixture of chicken manure, zeolite powder and calcium chloride with a water content of 60%-70% The weight ratio is 100:3:3, and the rw fermentation agent is added, stirred and mixed evenly, and then fermented at a temperature of 60°C for about 10 days to obtain the primary fermentation material;

[0020] (3) Final fermentation: ad...

Abstract

The invention discloses a technology for producing an organic fertilizer by fermenting dung of southern caged laying hens. The technology comprises steps of poultry dung treatment, primary fermentation, final fermentation and the like, and has the advantages that since furnace ash is added in the step of final fermentation, not only is a hygroscopic effect realized to reduce moisture content, but also ammonia volatilization caused by high alkalinity of the furnace ash is avoided effectively, loss of nutrient nitrogen is prevented, and reduction of the total nutrient is avoided; compared with that of the conventional southern organic fertilizer production technology, the fermentation time of the technology disclosed by the invention is shortened by more than 40 days, so that convenience is brought for factory production of the organic fertilizer; under the premise that the prescribed moisture content requirement is met, the organic fertilizer produced according to the technology disclosed by the invention is more than 10 percent in total nutrient content, and is kept more than 3 percent in N content.

Description

technical field [0001] The invention relates to a production process for fermenting organic fertilizer from cage-raised chicken feces in southern regions, and belongs to the technical field of organic fertilizer production. Background technique [0002] With the rapid development of the domestic breeding industry, especially the intensive and large-scale breeding of cage chickens such as laying hens, the number of breeding is huge, and the output of chicken manure is large and concentrated. If the chicken manure cannot be disposed of in time, it will lead to nowhere to pile up, or Long-term stacking will pollute the environment, so the manure produced by caged chickens has become one of the important factors restricting the deep development of breeding enterprises. [0003] In order to avoid the impact of too much chicken manure, the northern breeding enterprises generally ferment fresh chicken manure to make organic fertilizer or chicken manure feed. In the south, there is...
