Embodiment 1

[0083] The amount of microbial agent added to the soil is 37kg / hm 2 .

[0084] After measuring the soil nutrient content and enzyme activity, the measured organic matter content in the soil is 29.44g / kg, the content of alkaline nitrogen is 183.24mg / kg, the content of available phosphorus is 94.61mg / kg, and the content of available potassium is 305.23mg / kg The measured soil urease activity was 4.92mg / g·d, catalase activity was 3.40mg / g·h, and sucrase activity was 82.35mg / g·d.

Embodiment 2

[0086] The amount of microbial agent added to the soil is 44kg / hm 2 .

[0087] After measuring the soil nutrient content and enzyme activity, the measured organic matter content in the soil is 30.15g / kg, the content of alkaline nitrogen is 180.55mg / kg, the content of available phosphorus is 93.75mg / kg, and the content of available potassium is 312.01mg / kg The measured soil urease activity was 5.10mg / g·d, catalase activity was 3.09mg / g·h, and sucrase activity was 80.49mg / g·d.

Embodiment 3

[0089] The amount of microbial inoculum added to the soil is 48kg / hm2.

[0090] After measuring the soil nutrient content and enzyme activity, the measured organic matter content in the soil is 29.33g / kg, the content of alkaline nitrogen is 179.64mg / kg, the content of available phosphorus is 90.44mg / kg, and the content of available potassium is 294.72mg / kg The measured soil urease activity was 5.07mg / g·d, catalase activity was 3.15mg / g·h, and sucrase activity was 81.67mg / g·d.

Abstract

The invention is applicable to the technical field of microbial breeding, and provides bacillus amyloliquefaciens. The bacillus amyloliquefaciens is bacillus amyloliquefaciens PLBS010 and is preservedin China General Microbiological Culture Collection Center on December 17, 2018, and the preservation number is CGMCC NO.16950. The invention further provides an application of the bacillus amyloliquefaciens to soil nutrient content and enzyme activity. Therefore, the bacillus amyloliquefaciens PLBS010 disclosed by the invention has better high-temperature tolerance, acid-base tolerance, salt tolerance and pathogenic fungi inhibition, and by applying a microbial agent containing the bacillus amyloliquefaciens PLBS010 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 amyloliquefaciens 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 ...
