Embodiment 1

[0023] This embodiment provides an agricultural microbial fertilizer and a preparation method thereof.

[0024] 1. Adopt nutrient gravy medium to cultivate Bacillus licheniformis and Bacillus subtilis respectively; Taking the total weight of this medium as a basis, the percentage composition of peptone in this medium can be 0.5%, the percentage composition of NaCl can be 0.5%, The percentage composition of beef extract can be 0.2%, surplus is sterile water, and the pH value of this culture medium is 7.0; Culture method is conventional culture method, cultivates until the number of viable bacteria of bacillus licheniformis is (1~10) ×10 10 CFU / g, the number of live bacteria of Bacillus subtilis is (1~10)×10 10 CFU / g.

[0025] 2, adopt YPG culture medium to cultivate Bacillus coagulans; Taking the gross weight of this medium as a basis, the percentage composition of peptone in this medium is 0.25%, the percentage composition of glucose is 0.25%, and the percentage composition ...

Embodiment 2

[0036] This example is used to illustrate the fertilization method and fertilization effect of the agricultural microbial bacterial fertilizer provided by the present invention for soil. The soil selected in this embodiment is paddy soil, and the experimental site is Jiayuan Agricultural Development Co., Ltd., Nankou Town, Meixian County, Meizhou City, Guangdong Province. The plant of the experiment is Sijiu Caixin. The experimental unit is commissioned by the General Station of Fertilizers in Guangdong Province.

[0037] Experimental method: Wherein the experimental group: the agricultural microbial bacterial fertilizer prepared in Example 1 was inoculated in the soil, the mass ratio of the agricultural microbial bacterial fertilizer to the soil was 0.2:100, stirred evenly and then fermented, the fermentation temperature was 20 ℃, the fermentation time is 5 days, and the fertilized soil is obtained. Then plant Sijiu Chinese cabbage in the fertilized soil, the planting area is...

Abstract

The invention relates to an agricultural microbial fertilizer and a preparation method and application thereof. The agricultural microbial fertilizer comprises a medium and thalli. The thalli comprise bacillus subtilis, Bacillus megaterium, Bacillus mucilaginosus, Bacillus licheniformis, bacillus thuringiensis, bacillus laterosporus, Bacillus mucilaginosus, Streptomyces jingyangensis, azotobacter vinelandii, bacillus coagulans, Aspergillus oryzae and paecilomyces lilacinus. The agricultural microbial fertilizer provided by the invention can improve soil, can effectively control part of plant diseases and insect pests and can supply nutrients to soil to effectively solve a long-term problem of soil hardening. In addition, the agricultural microbial fertilizer can dissolve phosphorus and potassium so as to affectively release phosphorus, potassium, etc. existing in the form of a chelate in the soil.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to an agricultural microbial fertilizer and its preparation method and application. Background technique [0002] With the development of society, various environmental problems are becoming more and more serious. Various industrial waste gases, waste water, chemical fertilizers, pesticides and other pollutants have entered their final host - the soil, resulting in a decline in the quality of the soil environment, especially heavy metal pollution in the soil. . Heavy metal ions are trace elements necessary for plant metabolism, but if they are excessive, they are quite toxic, which has already attracted great attention from the society and the public all over the world. Due to the poor structure of heavy metal polluted soil and the lack of nutrients, heavy metals exist in the form of strong toxicity, which affects the growth of plants. Therefore, it is necessary to study th...
