Abstract

The invention relates to a high-temperature-resistant, deodorizing, nitrogen-preserving fermented organic fertilizer and a preparation method thereof. In the process of secondary high-temperature fermentation and composting of metabolized biomass after biotransformation of organic waste, the bacterial agent has high-temperature resistance, deodorization and nitrogen retention. Composition of Bacillus, Rhodopseudomonas palustris, Lactococcus lactis and Saccharomyces cerevisiae. The high-temperature-resistant deodorizing and nitrogen-conserving active bacterial agent provided by the present invention utilizes the synergistic effect between organic matter-degrading microbial bacteria, pathogenic bacteria, deodorizing bacteria and high-temperature-resistant acid-producing bacteria, and has novel strain combinations, stable structure, strong activity, It has the characteristics of high bacterial count, and at the same time solves the problems of slow degradation of organic matter including traditional organic fertilizer compost and metabolite compost of bio-transformation organic waste, ineffective deodorization effect, low nitrogen content of compost finished products, etc., and improves the efficiency of organic fertilizer. Treatment efficiency and nutrient use efficiency.

Description

technical field [0001] The invention belongs to the field of ecological breeding, and relates to a secondary composting treatment technology of metabolized biomass after biologically transforming kitchen waste, in particular to a preparation method of a high-temperature-resistant, deodorizing, nitrogen-conserving organic fertilizer fermentation bacterial agent. Background technique [0002] With the rapid development of my country's social economy and the rapid advancement of modern agriculture, the amount of kitchen waste from urban residents is not only increasing rapidly, but also contains a large amount of water, oil, salt and various nutrients, which are difficult to dispose of through traditional garbage treatment methods. In the research and development process of various decomposition treatments, the biotransformation treatment method gradually shows its advantages. For example, the invention of application number CN201510380599.0 discloses a method for efficiently bi...
