Effects of AMF inoculation on plant-soil ecological stoichiometry and nutrient recovery in Shendong mine

Vegetation restoration and microbial reclamation of mining subsidence area is the key spot to construct green mine.The effects of Arbuscular Mycorrhizal Fungi (AMF) and re-vegetation types on the ecological chemometric characteristics of the plant-litter-soil continuum and leaf nutrient resorption are still unclear, but are important for illuminating nutrient cycling and sustainable development after ecological restoration in arid coal mining subsidence areas in Northwest China. Five types of restored vegetation and the 0～10 cm soil of the corresponding vegetation were selected for study in the reclamation of 10 years of inoculation with AMF and the control area—Amorpha fruticosa, Hippophae rhamnoides, Xan-thoceras sorbifolium, Cerasus humilis and Cerasus szechuanica.The intention was to explore the influences of inoculum and re-vegetation type on C, N and P contents and ecological stoichiometric ratios, nutrient recovery rates, and nutrient limitation within the plant-litter-soil continuum.
