Arbuscular mycorrhizal fungi (AMF) technology of bioremediation becomes one of the most hotspots in the research
on coal-mining subsidence land. This article based on amorpha fruiticosa planting in the mining subsidence of
Shendong mining area as a study object, arbuscular mycorrhizal fungi was vaccinated on amorpha fruiticosa after different
monitor time, respectively measures are used to analyze its effect on the growth of plant and on rhizosphere soil
physical properties. The correlation between hyphae density and Olsen-P of rhizosphere is analyzed. By using regression
analysis, we found that in different monitoring time, hyphae density and effective phosphorus in September had better linear
fitting than that in June, which is closely associated with development time of mycorrhizal. With the time passing by,
the correlation of vaccination between hyphae density and effective phosphorus content is gradually decreased; however,
the positive correlation of un-vaccinated is gradually emerged. The results of mycorrhizal bioremediation on mining subsidence
in Shendong mining area prove that vaccination not only could effectively promote growth and development of
amorpha fruiticosa in macroscopic, but also could improve the growth matrix conditions in microscopic.
