Embodiment 1

[0037] a. Prepare materials: collect pig manure, dry it to make its moisture content less than 75%, collect auxiliary materials with an organic matter content greater than 60%, crush and sieve them so that the diameter of the auxiliary materials does not exceed 2cm, dry them in the sun or dry them so that their moisture content does not exceed 50%, And stack it naturally until white mycelium grows to prepare organic material decomposing agent;

[0038] b. Aerobic fermentation: mix 80% of the prepared pig manure dry basis mass with auxiliary materials evenly and adjust the water content in the range of 60-70%, add organic material decomposing agent and stir, so that the effective number of viable bacteria in the material reaches 50 10,000 per gram, and then pile up the stack for aerobic fermentation. During the aerobic fermentation, when the ammonia gas is pungent, add acidic substances containing phosphorus to make the pH of the stack at 5.5, and the stacking temperature should...

Embodiment 2

[0041] a. Prepare materials: collect pig manure, dry it to make its moisture content less than 75%, collect auxiliary materials with an organic matter content greater than 60%, crush and sieve them so that the diameter of the auxiliary materials does not exceed 2cm, dry them in the sun or dry them so that their moisture content does not exceed 50%, And stack it naturally until white mycelium grows to prepare organic material decomposing agent;

[0042] b. Aerobic fermentation: Mix 95% of the prepared pig manure dry basis mass and auxiliary materials evenly and adjust the water content in the range of 50-60%, add organic material decomposing agent and stir, so that the effective number of viable bacteria in the material reaches 50 10,000 pieces per gram, and then stack the material for aerobic fermentation. During the aerobic fermentation, when the ammonia gas is pungent, add acidic substances containing phosphorus to make the pH of the material 5.5, and the temperature of the m...

Abstract

The invention discloses a technique for manufacturing an active phosphorus organic fertilizer from pig manure, which comprises the following steps: raw material pretreatment, anaerobic fermentation, aerobic fermentation and aging. The weight percent of the raw material pig manure on dry basis is 70-95%. An auxiliary material with the organic content of higher than 60% is utilized to regulate the total water content of the pig manure and auxiliary material to 50-70%; an organic matter decomposing inoculant is added until the effective viable count in the total material is up to 0.5 million/g; and in the aerobic fermentation period, a phosphorous acidic matter is utilized to regulate the pH value to be greater than or equal to 5.5 and smaller than or equal to 8.5. The technique can effectively treat the cultivation farm excrement, enhances the index stability of the fertilizer, greatly reduces the effluvium generated in the fertilizer production process, and enhances the phosphorus utilization ratio and humus content. The active phosphorus organic fertilizer has the advantages of high thermal insulation, high fertility retention and high air permeability, contains more activated phosphorus element, and thus, has excellent promotion effects on crop root system growth, seed development and the like.

Description

【Technical field】 [0001] The invention relates to a process for making active phosphorus organic fertilizer by using pig manure, and belongs to the technical field of agricultural fertilizer production. 【Background technique】 [0002] At present, the country's management and control of waste in the breeding industry is becoming more and more strict, and the treatment of animal excrement is facing a severe situation. Many farms are facing the situation of rectification, closure and relocation. In fact, breeding enterprises can easily and effectively deal with animal waste to make it harmless, reduce, and recycle, so that they can get out of subsidizing others to take away pig manure or sell it at a low price, or if it is not handled in time dilemma, but also can get a lot of profits from the sale of fertilizers. [0003] Due to the lack of professionals in solid fermentation technology and practical work experience, most enterprises will produce foul odors during the ferment...
