Problems solved by technology

[0003] However, due to the poor conditions of the mining areas, some mining areas do not even have soil or water resources are extremely scarce
In conventional bioremediation methods, the selection of plant species is single, the survival rate of planting is low, and some cannot grow normally, etc.

Abstract

The invention relates to the field of microbial remediation, in particular to microorganism composite preparation and application thereof. The microorganism composite preparation mainly comprises arbuscular mycorrhizal fungi and Glomus versiforme. The invention further provides the application of the microorganism composite preparation in soil improving. The microorganism composite preparation has the advantages that the arbuscular mycorrhizal fungi is used together with the Glomus versiforme, the use effect of the microorganism composite preparation is evidently better than that of the independent arbuscular mycorrhizal fungus inoculant or Glomus versiforme inoculant, biomass increasing can be evidently promoted, soil structure can be improved, soil remediation can be achieved, heavy metal contents are lowered, and soil continuous cropping is overcome.

Description

technical field [0001] The invention relates to the field of microbial remediation, in particular to a microbial composite preparation and its application. Background technique [0002] With the construction of the ecological environment, the ecological environment of the closed mining areas in my country is fragile, the site environmental conditions are poor, the repair cost is high, the effect is poor, and the repair effect is unstable. Even, the seriously polluted mining areas still have hazards to the lives and lives of the mining areas and surrounding residents. safe question. The current ecological restoration can use physical methods to fix soil and plant plants for ecological restoration. [0003] However, due to poor production conditions in mining areas, some mining areas do not even have soil or water resources are extremely scarce. In conventional bioremediation methods, the selection of plant species is single, the survival rate of planting is low, and some can...
