Embodiment 1

[0021] This example provides a soil-improving microbial agent for winter jujube in a solar greenhouse and a preparation method thereof.

[0022] 1. Adopt nutrient gravy microbial medium to cultivate Bacillus subtilis respectively; take the total weight of this microbial medium as a basis, the percentage composition of peptone in this microbial medium can be 0.5%, the percentage composition of NaCl can be 0.5%, beef The percentage composition of ointment can be 0.2%, surplus is sterile water, and the pH value of this microorganism culture medium is 7.0; Culture method is conventional culture method, cultivates until the number of viable bacteria of bacillus subtilis is (2~4) billion / ml.

[0023] 2. Microbial culture medium for respectively cultivating jelly-like Bacillus and brown nitrogen-fixing bacteria. Each 100g of microbial culture medium used includes: 2g of sucrose, 5g of mannitol, 1g of ammonium sulfate, 1g of peptone, 2g of beef extract, and 1g of sodium chloride , Po...

Abstract

The invention discloses a special soil improved microbial agent for winter jujubes in a solar greenhouse and a preparation method thereof. The invention relates to the fields of microbial technologiesand agricultural soil science and in particular relates to a special microbial agent for winter jujubes in a solar greenhouse. The microbial agent comprises a microbial culture medium and thalli, wherein the thalli comprise bacillus subtilis, bacillus thuringiensis, bacillus mucilaginosus, azotobacter vinelandii, aspergillus oryzae and paecilomyces lilacinus. The special microbial agent providedby the invention can achieve the effects of improving soil, effectively controlling part of plant diseases and insect pests, supplementing nutrition to soil and effectively solving the problems, suchas soil hardening, existing in cultivation of winter jujubes in a solar greenhouse for a long time. Moreover, phosphorus, potassium and the like existing in a chelate form in soil can be effectively released.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a special soil-improving microbial agent for winter jujube in a solar greenhouse and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of protected horticulture in northern my country, the planting of winter jujube in solar greenhouses has become very common. With the extension of cultivation time, due to the unreasonable management and utilization of soil, fertilizer and water, the soil environment quality in solar greenhouses is declining day by day, especially soil pesticides, The pollution of chemical fertilizers and heavy metal ions directly affects the yield and quality of winter jujube, which has attracted great attention from the society and the public all over the world. Due to poor soil structure and lack of nutrients, it also affects the growth of winter jujube. Therefore, it is necessary to study the sources...
