Facultative anaerobic fermentation fungicide and method for preparing organic fertilizer through facultative anaerobic fermentation fungicide

Abstract

The invention discloses a facultative anaerobic fermentation fungicide. The facultative anaerobic fermentation fungicide is prepared from facultative anaerobic fermentation flora. The facultative anaerobic fermentation flora is prepared from lactic acid bacteria, lactobacillus acidophilus, bacillus subtilis, bacillus licheniformis, bacillus coagulans, aspergillus oryzae, bacillus megatherium, bacillus laterosporus, bacillus thuringiensis, streptococcus faecium, photosynthetic bacteria, saccharomycetes, paecilomyces lilacinus, nitrogen-fixing bacteria and actinomycetes. The facultative anaerobic fermentation fungicide can be suitable for facultative anaerobic fermentation of organic fertilizer, organic matter can be efficiently converted, and growth of pernicious bacteria can be inhibited. The invention also discloses a preparing method of the organic fertilizer, in the method, facultative anaerobic fermentation is carried out through the facultative anaerobic fermentation fungicide, the fermentation cycle is short, the running cost is low, the organic fertilizer prepared with the method is rich in nutriment, environmentally friendly and harmless, and development of ecological agriculture can be promoted.

Description

technical field [0001] The invention relates to the field of organic fertilizer production, in particular to a facultative fermentation bacterial agent and a method for producing organic fertilizer. Background technique [0002] Three-dimensional circular agriculture requires the production of ecologically healthy agricultural products (organic food) without any pollution or secondary pollution caused by waste and harmful substances. This requires that supporting planting, breeding and internal treatment and digestion of waste must be carried out in the production of organic food. This process usually uses microorganisms to harmlessly treat the waste generated in agricultural production (straw, wheat husk, rice husk, grass, livestock and poultry manure) into high-quality organic fertilizer and return it to the soil. [0003] At present, the preparation of organic fertilizer from organic waste is mainly through anaerobic fermentation or aerobic fermentation. The decompositio...

AI Technical Summary

Problems solved by technology

In anaerobic fermentation, the decomposition of organic matter is slow, and the production efficiency of organic fertilizer is low. It generally takes several months, and the equipment required for anaerobic fermentation requires high requirements and large investment. Aerobic fermentation has high decomposition efficiency of organic matter and a short composting cycle, but the fermentation process requires continuous supply. Oxygen, high operating costs

[0004] The organic fertilizer prepared by the above two fermentation methods usually has the phenomenon that the organic matter and nutrients are not up to the standard. When it is applied to crop planting, the effect of promoting crop growth is poor and affects crop yield.

On the other hand, the content of heavy metals, harmful germs, weed seeds and pest eggs in the prepared organic fertilizers often exceeds the standard, and when they are returned to the soil, they will often pollute the soil. The process of applying this organic fertilizer is undoubtedly unintentional. The process of transferring and amplifying contamination is not conducive to environmental safety and food safety

Therefore, the existing organic fertilizer fermentation process is difficult to meet the needs of ecological and healthy agriculture
