Embodiment 2

[0044] A method for producing compound microbial fertilizer by utilizing lactic acid industrial waste, comprising the following steps: firstly, the lactic acid residue is neutralized by using dilute hydrochloric acid with a concentration of 26-28% to neutralize the lactic acid residue, so that the calcium hydroxide component remaining in the lactic acid residue is Neutralize reaction with hydrochloric acid, adjust the pH value to 7.0~8.0, then use yeast for fermentation treatment, then age for 3~5 days, and control the moisture at 10~15% after ageing; crush to 60~100 mesh humus Acid and straw ash, ammonium bicarbonate or / and calcium superphosphate are mixed in proportion, and the retting material is obtained by adding water for 7-14 days. The ratio of humic acid, straw ash, ammonium bicarbonate or / and calcium superphosphate and water 10: 2: 2: 2 to 3; secondly, carry out retting treatment with humic acid, straw ash, ammonium bicarbonate or / and calcium superphosphate, and water ...

Embodiment 3

[0051] A method for utilizing lactic acid industrial waste to produce compound microbial fertilizer, comprising the following steps: firstly, using the lactic acid residue with a concentration of 26% dilute hydrochloric acid to neutralize the lactic acid residue, so that the residual calcium hydroxide component in the lactic acid residue and the hydrochloric acid are Neutralization reaction occurs, adjust the pH value to 8.0, then use yeast for fermentation treatment, and then age for 3 days. After ageing, the moisture is controlled at 10-15%; humic acid, straw ash and ammonium bicarbonate will be crushed to 100 mesh. Or / with superphosphate mixed in proportion, adding water for 14 days to obtain retting material, the ratio of humic acid, straw ash, superphosphate, water is 10: 2: 2: 2; secondly, humic acid, straw Ash, superphosphate, and water are subjected to retting treatment to obtain retting material; finally, the treated milk fungus residue and retting material are mixed w...

Abstract

The invention provides a method for producing a composite microorganism fertilizer by utilizing lactic acid industrial wastes. The method comprises the following steps: firstly, acidifying and neutralizing lactic acid slag in advance, then fermenting with saccharomycetes, and subsequently ageing and smashing; then, retting humic acid, straw ash, ammonium bicarbonate or / and calcium superphosphate and water so as to obtain a retted material; and finally, mixing the treated lactic acid slag and retted material with a pelleting adjuvant and a plant growth regulating agent, then pelleting, drying,cooling and screening, adding microorganism bacteria in fertilizer particles obtained after screening through adoption of a spraying and packing process, and finally, carrying out caking resisting treatment. In the method provided by the invention, saccharomycete fermentation is adopted, thereby the problem that drying cost is high is solved; and the spraying and packing process after screening is adopted, thereby the problem that a large amount of strains subjected to drying die is solved.

Description

technical field [0001] The invention relates to a production method of a composite microbial fertilizer, in particular to a production method of a composite microbial fertilizer that utilizes lactic acid industrial waste and combines with humic acid, straw ash, plant growth regulators and microbial bacteria. Background technique [0002] The output of lactic acid industrial waste is large, which contains beneficial elements such as organic matter, nitrogen, phosphorus and potassium, active calcium, etc., because it cannot be directly used by crops, the treatment cost is high, and it accumulates everywhere and pollutes the environment. The lactic acid residue of the lactic acid industrial waste contains 50-55% moisture and 10-12 pH value, and the drying treatment cost is high, and the organic components cannot be decomposed. [0003] In the production of domestic microbial fertilizers, microbial bacteria are added before granulation. The mortality rate of microbial bacteria a...
