Method of fermenting organic fertilizer with chicken manure

Abstract

The invention discloses a method of fermenting an organic fertilizer with chicken manure. The method comprises the steps of chicken manure treatment, primary fermentation, and final fermentation. Themethod has the advantages that since addition is performed at the end of the fermentation, effects of absorbing moisture and reducing a moisture content are exerted; ammonia volatilization due to strong basicity of stove ash is effectively avoided; a nitrogen nutrient loss and reduction of total nutrients are avoided; compared with the existing south organic fertilizer production time, the fermentation time is shortened by more than 40 days; the industrial production of the organic fertilizer is facilitated; and the organic fertilizer produced by the method ensures that a total nutrient content is above 10% and an N content is kept above 3% on the basis that a specified moisture content requirement is met.

Description

technical field

[0001] The invention relates to a method for fermenting organic fertilizer with chicken manure, 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 excessive chicken manure, no matter it is dried in advance or after the fermentation is completed, the ammonia gas volatilizes severely during the fermentation process, causing the loss of nitrogen nutrients, and th...

Embodiment 1

[0013] Embodiment 1: the method for fermenting organic fertilizer with feces of southern laying hens, 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% to prepare chicken manure with a water content of 60%-70% for subsequent use. Wherein, the amount of free-range dry chicken manure and cage-raised dilute chicken manure is based on the mixed chicken manure with a water content of 60%-70%;

[0015] (2) Initial fermentation: adding zeolite powder and calcium chloride to chicken manure with a water content of 60%-70%, wherein 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 purchased dire...
