Embodiment 2

[0044] A method for producing compound microbial fertilizer from industrial wastes of lactic acid, including the following steps: firstly, the lactic acid residue is neutralized by using dilute hydrochloric acid with a concentration of 26-28% to make the calcium hydroxide remaining in the lactic acid residue It neutralizes with hydrochloric acid, adjusts the PH value to 7.0~8.0, and then uses yeast fermentation treatment, then aging for 3~5 days, after aging, the moisture content is controlled at 10~15%; crushing to 60~100 mesh hum The acid is mixed with straw ash, ammonium bicarbonate or / and superphosphate in proportion, and water is added for retting for 7-14 days to obtain the refining material. The proportion of humic acid, straw ash, ammonium bicarbonate or / and superphosphate and water It is 10:2:2:2~3; secondly, the humic acid, straw ash, ammonium bicarbonate or / and superphosphate, water are retorted to obtain the retorted material; finally, the treated milk bacteria resid...

Embodiment 3

[0051] A method for producing compound microbial fertilizer from industrial wastes of lactic acid includes the following steps: firstly, the lactic acid residue is neutralized with dilute hydrochloric acid at a concentration of 26%, so that the remaining calcium hydroxide in the lactic acid residue is combined with hydrochloric acid. Neutralization occurs, adjust the PH value to 8.0, and then use yeast fermentation treatment, then aging for 3 days, after aging, the moisture content is controlled to 10-15%; crush to 100 mesh humic acid, straw ash, ammonium bicarbonate Or / and superphosphate are mixed in proportion, and water is added for retting treatment for 14 days to obtain refining materials. The ratio of humic acid, straw ash, superphosphate, and water is 10:2:2:2; secondly, humic acid, straw Retting the ash, superphosphate and water to obtain the retting material; finally, the treated milk bacteria residue and retting material are mixed with the granulation auxiliary and pla...

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 method for producing a compound microbial fertilizer, in particular to a method for producing a compound microbial fertilizer that utilizes industrial waste of lactic acid and is combined with humic acid, straw ash, plant growth regulators, and microorganisms. Background technique [0002] The output of lactic acid industrial waste is large, which contains beneficial elements such as organic matter, nitrogen, phosphorus, potassium, and active calcium. Because it cannot be directly used by crops, the processing cost is high, and it accumulates everywhere and pollutes the environment. The lactic acid industrial waste lactic acid residue contains 50-55% moisture and 10-12 PH value. The drying process is costly and cannot decompose organic components. [0003] The production of domestic microbial fertilizer adopts the addition of microbial bacteria before granulation. The death rate of microbial bacteria is high after the drying process...
