Organic fertilizer raw material fermentation process

Abstract

The invention relates to the technical field of organic fertilizers and in particular relates to an organic fertilizer raw material fermentation process which comprises the following steps: adding anacid and base regulator to a fermentation tank, and introducing air into the fermentation tank every other 2 hours, and continuously stirring an organic fertilizer to reduce the total amount of anaerobic microorganisms in the organic fertilizer; introducing air flows of 60-75 DEG C into the fermentation tank to accelerate maturation of the organic fertilizer, wherein the maturation cycle is 7-10 days; pouring the maturated organic fertilizer into a reaction kettle at a temperature of 150-200 DEG C, and performing uniform stirring and mixing, wherein the stirring time is not less than 5 hours;and performing room temperature fermentation on the treated organic fertilizer, wherein the fermentation time is 5-7 days. The process has the beneficial effects that through the step 1), the contentof anaerobic microorganisms in the organic fertilizer is reduced, so that during the fermentation process, the number of anaerobic microorganisms is reduced, while the number of aerobic microorganismsis increased, and thus the fermentation efficiency can be accelerated; and the acid and base regulator is adopted to neutralize the acidity and alkalinity of organic matter, so that imbalance of acids and bases of organic matter is avoided, and the fermentation process is prevented from being affected.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a fermentation process for organic fertilizer raw materials. Background technique [0002] Bio-organic fertilizer refers to a type of microbial fertilizer and organic fertilizer that is composed of specific functional microorganisms and organic materials that are mainly sourced from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. Fertilizer with fertilizer effect. [0003] Advantages of bio-organic fertilizers over chemical fertilizers: [0004] 1) Bio-organic fertilizers have complete nutritional elements; chemical fertilizers have only one or several nutritional elements; [0005] 2) Bio-organic fertilizers can improve the soil; frequent use of chemical fertilizers will cause soil compaction; [0006] 3) Bio-organic fertilizers can improve product quality; excessive application of...

[0006] 3) Bio-organic fertilizers can improve product quality; excessive application of chemical fertilizers leads to poor product quality;

[0009] Organic fertilizers generally use animal manure, kitchen waste, and crop straw as raw materials, and put them into fermentation tanks for fermentation, but the existing fermentation process is less efficient
