AI Technical Summary

Technical Problem

Existing microbial fertilizer formulations are unreasonable, and the processing methods lack fermentation metabolites, which affects the efficacy of microbial fertilizers and fails to effectively solve the problem of crop rotation obstacles.

Method used

Microbial preparations were prepared by fermenting a mixture of Bacillus subtilis, Bacillus thuringiensis, Bacillus licheniformis, and Bacillus megaterium with shrimp and crab shells, collagen, sodium chloride, amino acids, carbohydrates, and compound fertilizers to increase the number of viable bacteria and improve the soil microecology.

Benefits of technology

It significantly inhibits plant pathogens, increases soil trace element content, improves crop continuous cropping obstacles, and reduces crop disease incidence and soil biological activity.

Abstract

The present application relates to the field of microbial agricultural technology, and more particularly to a microbial preparation, a preparation method thereof and application thereof in improving continuous cropping obstacles, and provides a microbial preparation, a preparation method thereof and application thereof, wherein the microbial preparation is prepared by fermentation of Bacillus subtilis, and the fermentation culture solution contains shrimp and crab shells, collagen, sodium chloride, amino acids, carbohydrates and compound fertilizer, so that the preparation can not only inhibit harmful bacteria, but also provide a large amount of nutrients for crops. Experiments show that the microbial preparation provided by the present application can make the inhibition zone of the bacterial agent on pathogenic bacteria reach more than 6 times that of the control group. Field experiments show that the bacterial agent can significantly increase the content of trace elements in soil and improve the diseases of ginseng, panax notoginseng and rehmannia caused by continuous cropping.
