Massilia bacteria, bacterial agent, preparation method and application thereof

By using the inoculant *Bacillus simonii* to dissolve inorganic phosphorus and inhibit *Sclerotinia sclerotiorum*, the problems of low phosphate fertilizer utilization and sclerotinia sclerotiorum disease in rapeseed were solved. This achieved the growth-promoting and disease-preventing effects of biological agents on rapeseed, avoiding the resistance and environmental pollution caused by chemical pesticides.

AI Technical Summary

Technical Problem

Rapeseed growth is affected by low phosphate fertilizer utilization and sclerotinia stem rot. The use of existing chemical pesticides has led to pesticide resistance and environmental pollution problems. There is a lack of biological agents that can simultaneously solve the problems of phosphate dissolution and sclerotinia stem rot control.

Method used

A microbial agent was prepared using specific strains of *M. muscarinii* (CCTCC NO: M 2026202, CCCTCC NO: M 2026203, or CCCTCC NO: M 2026201) to dissolve inorganic phosphorus and inhibit *Sclerotinia sclerotiorum*. It was applied to rapeseed by root irrigation or spraying.

Benefits of technology

This study achieved the goal of promoting rapeseed growth under low phosphorus conditions and effectively controlling sclerotinia disease, providing an environmentally friendly biological agent solution to replace chemical fertilizers and pesticides.

Abstract

This invention relates to the field of microbial technology, specifically to a *Morchella esculenta* strain, its preparation method, and its applications. The *Morchella esculenta* strain of this invention has the preservation number CCTCC NO: M 2026202, M 2026203, or M 2026201. The inoculant of this invention includes the aforementioned *Morchella esculenta*. The *Morchella esculenta* strain and its inoculant of this invention not only dissolve inorganic phosphorus and promote rapeseed growth, but also enhance rapeseed's resistance to sclerotinia stem rot by inhibiting *Sclerotinia sclerotiorum*.
