Inoculation effect of arbuscular mycorrhizal fungi in the soil reconstruction of gangue

According to the main problems existing in ecological restoration of coal gangue tailings, the experiment by biological measures in the natural condition of arbuscular mycorrhizal fungus Glomus Mose袁was studied on the ecological impact on the coal gangue soil remediation. The results showed that after inoculation of Glomus mosseae for eight month, it was significantly promoted the survival rate, which increased by more than 30%, mycorrhizal colonization in rhizosphere was more than 50%, content of heavy metals in soil decreased significantly compared with the control袁especially the Mn content of different plants in soil decreased by 49.83 mg/kg, 24.73 mg/kg, 44.45 mg/kg compared to control, and Copper and cadmium also had varying degrees of decline, but the organic matter and nitrogen content in soil were improved significantly. The organic matter and nitrogen top increased by 65.78%, 84.08%. The research indicates that, arbuscular mycorrhizal had good inoculation effect in the soil reconstruction by of the ecological mountain coal gangue.
