Preparation process for producing tobacco organic compound fertilizer by utilizing animal manure

Abstract

The invention discloses a preparation process for producing a tobacco organic compound fertilizer by utilizing animal manure. The preparation process is characterized in that: the fermentation process comprises the following stages: the first stage: mixing fresh pig manure with straw or bacterial residues, adding into a special stainless steel fermentation tank after mixing, heating to 70-90 DEG C, simultaneously uniformly adding a strain, performing fermentation operation, simultaneously performing stirring operation during the heating process, stirring to enable the temperature of contents to be uniform, killing harmful bacterial and insect eggs, switching off after heating for a period of time, maintaining at the temperature of 70-90 DEG C by relying on heat energy of fermenting organisms, and taking out of the tank after 12-24h; the second stage: adopting an air inflation pump and an air inflation pipeline to perform high-pressure air inflation and accumulation for further fermentation so as to realize further loss of part of water; and the third stage: adding trace elements, uniformly stirring, then granulating, further spraying a functional microorganism fertilizer on the surface, and bagging.

Description

technical field [0001] The invention relates to a preparation process of organic compound fertilizer, in particular to a preparation process of making tobacco organic compound fertilizer by using livestock and poultry manure. Background technique [0002] For a long time, there has been a phenomenon of emphasizing inorganic fertilizers and neglecting organic fertilizers in tobacco production in my country. Due to the long-term and large-scale application of chemical fertilizers and the decrease in the amount of organic fertilizers year by year, soil compaction, environmental pollution, decline in tobacco leaf quality, light color, reduced oil content, insufficient aroma, poor taste, thin leaves, and light weight of single leaves, etc. It has become one of the main limiting factors of quality-benefit flue-cured tobacco production. [0003] Since the beginning of this century, the research on making organic fertilizer from livestock and poultry manure has begun to rise, but d...
