Bacillus subtilis B51 and application of bacillus subtilis B51

Abstract

The invention discloses bacillus subtilis B51. The preservation serial number of the bacillus subtilis B51 is CGMCCNo.7541; the preservation date of the bacillus subtilis B51 is April 28, 2013; the bacillus subtilis B51 is named as Bacillus subtilis and has been preserved in the general microbiology culture preservation management center of China. The bacillus subtilis B51 plays a good role in inhibitingvarious pathogenic funguses such as the dendrobium officinale ceitocybe bescens, the wheat scab and the grey mould fruit rot of strawberries, and antagonistic bacteria play a good role in preventing and treating other plant diseases; the bacillus subtilis B51 has the advantages of being high in breeding speed, easy to operate, convenient to produce and apply, high in resilience capacity, capable of being artificially cultivated and the like; in particular, the bacillus subtilis B51 is of important significance in preventing and treating the dendrobium officinale ceitocybe bescens caused by the funguses; culture conditions are simple, preservation is easily carried out, industrial production is easily achieved, and the bacillus subtilis B51 has good development and application prospects.

Description

technical field [0001] The invention belongs to the field of plant protection, in particular to a Bacillus subtilis B51 and its application in preventing and treating root rot of dendrobium officinale. Background technique [0002] In recent years, with the general concern of the public on the safety of chemical pesticides in food and the environment, and the prohibition of some dangerous chemical pesticides, people are seeking new ways to control plant diseases safely and effectively, and the use of beneficial microorganisms to control plant diseases has attracted increasing attention. It introduces exogenous antagonistic bacteria beneficial to plants into the broken plant natural ecosystem, or promotes the growth of natural beneficial microbial populations by regulating the environment, and exhibits biological control activity, and achieves disease prevention through the interaction between microorganisms Purpose. At present, the biocontrol of plant diseases has become th...

Problems solved by technology

[0008] However, for more than ten years, with the continuous expansion of the artificial cultivation area of ​​Dendrobium candidum, the occurrence of diseases and insect pests is common and serious, especially the occurrence of root rot of Dendrobium candidum, which sometimes causes large areas of death in patches, resulting in huge economic losses. Therefore, the prevention and treatment of Dendrobium officinale root rot has practical significance
