Abstract

The invention is applicable to the technical field of microbial breeding, and provides bacillus subtilis. The bacillus subtilis is bacillus subtilis PLBS015, is preserved in China General Microbiological Culture Collection Center on December 17, 2018, and has a preservation number of CGMCC NO.16953. The invention further provides an application of the bacillus subtilis to soil nutrient content andenzyme activity. Therefore, the bacillus subtilis PLBS015 has good high-temperature tolerance, acid tolerance, antibacterial activity and safety, when the microbial agent containing the bacillus subtilis PLBS015 is applied to soil, soil nutrient imbalance and soil-borne disease aggravation can be avoided, and crop growth and development and stable, healthy and sustainable development of agricultural production are promoted.

Description

technical field [0001] The invention relates to the technical field of microbial breeding, in particular to a bacillus subtilis and its influence on soil nutrient content and enzyme activity. Background technique [0002] Soil is the material basis for the growth and survival of crops, and the sustainable use of soil is the prerequisite for the stable development of agricultural production. In the soil ecosystem, soil enzymes participate in biochemical processes such as the decomposition of soil litter and fallen leaves, the decomposition and synthesis of various organic substances, nutrient release, and circulation. The activity of soil enzymes directly or indirectly affects various Material transformation and circulation rate. Factors affecting soil enzymes mainly include soil microorganisms, soil physical and chemical properties and nutrients, planted crops, and fertilization measures. Soil microorganisms and crop roots are the main sources of soil enzymes, and their act...
