Abstract

The invention provides an AM fungal agent and an application method thereof, and relates to the technical field of mine repair. The AM fungal agent comprises an AM fungal culture medium and a host plant root system, wherein the AM fungal culture medium comprises a strain culture medium and AM fungi, and the strain culture medium comprises, by weight, 20-50 parts of zeolite, 5-30 parts of vermiculite, 5-30 parts of river sand and 2-5 parts of a water retaining agent. The application method of the AM fungal agent comprises the following steps: S1, sequentially adding a mine matrix modifier, minesoil and the AM fungal agent into a planting pit; S2, transplanting a nursery stock into the planting pit, adding mine soil again, and carrying out AM fungus infection planting. The AM fungal agent and application method thereof can ensure the adaptability of the propagation strain in a semi-arid mining area and effectively improve the activity and spore yield of the strain after the fungal agentis used; meanwhile, the method can obviously improve the nutrient and water conditions of the land in the mining area, improve the biomass of the vegetation, and accelerate the recovery rate and quality of the vegetation in the mining area.

Description

technical field [0001] The present application relates to the technical field of mine restoration, in particular to an AM fungal agent and its application method. Background technique [0002] The development and utilization of mineral resources has made great contributions to the rapid development of my country's economy and urbanization, but its extensive over-exploitation has also caused a series of environmental problems and seriously damaged the local ecological environment. It causes dust weather, soil erosion, landslides, landslides and other natural geological disasters, leading to the degradation or even collapse of the ecosystem, which seriously threatens the sustainable development of surrounding areas and regional ecological security. There is an urgent need to restore and rebuild degraded mining ecosystems. [0003] Vegetation restoration is an important part of mine ecological restoration. Vegetation restoration not only plays a role in building initial vegeta...
