Ectomycorrhizal fungus complex microbial agent

Abstract

The invention discloses an ectomycorrhizal fungus complex microbial agent. The ectomycorrhizal fungus complex microbial agent is prepared from 4-8 parts of complex ectomycorrhizal fungi, 2-6 parts of bacteria for dissolving phosphorus and potassium, 2-6 parts of compound mildew, 20-30 parts of straw powder, 20-30 parts of coconut velvet, 5-10 parts of ammonium molybdate, 2-6 parts of boracic acid, 3-8 parts of polyvinyl alcohol, 10-15 parts of 2-hydroxypropyl-beta-cyclodextrin, 10-15 parts of chitosan, 1-5 parts of growth hormone and 10-20 parts of olive fruit residues, wherein the complex ectomycorrhizal fungi are prepared by mixing pisolithus tinctorius, lactarius deliciosus and suillus bovinus; the bacteria for dissolving the phosphorus and potassium are bacillus megatherium and bacillus mucilaginosus; the compound mildew is a mixture of trichoderma longibrachiatum and streptomyces jingyangensis; various inoculants synergistically act to give play to a group joint action, and finally, a microbial community which is complex in composition, stable in structure and wide in function is formed. The plant and root growth can be promoted, the absorption of nutrient and water can be improved, it is achieved that the infection of a same host plant and different bacteria is diversified, nutrient absorption of the host plant is greatly improved, and the biomass is significantly improved.

Description

technical field [0001] The invention relates to a composite microbial agent, in particular to an ectomycorrhizal composite bacterial agent for seedling cultivation and afforestation. Background technique [0002] Every process in an ecosystem is accompanied by the activities of various microorganisms, one of the most important functional groups being mycorrhizal fungi (mycorrhizal fungi). Mycorrhizal fungi are the most basic part of the survival of most plants in nature. More than 90% of higher plants on land can form mycorrhizae, and 73.9% of woody plants can form ectomycorrhizae. Ectomycorrhizal fungi can form Through its own absorption and retention, it can reduce the effectiveness and toxicity of soil heavy metals to plants. At the same time, ectomycorrhizal fungi are also beneficial to improve the growth of trees, enhance their resistance (tolerance) to heavy metals, and increase the survival rate of afforestation under heavy metal stress conditions. The mycelium of t...
