Abstract:
Objective:To investigate the effect of different arbuscular mycorrhizal （AM） fungi combinations on the rhizospheric environment of Paris polyphylla var. yunnanensis. Method:The different combinations of 12 arbuscular mycorrhizal （AM） fungi species were inoculated to the seedlings P. polyphylla var. yunnanensis planted in the sterilized soil under the condition of room temperature to investigate their infection abilities and effects on the root activity，soil nutrient contents，enzyme activities and microbial community structure of P. polyphylla var. yunnanensis rhizospheric environment. Result:The inoculation of exogenous AM fungi can regulate the spore densities and infection rate of P. polyphylla var. yunnanensis rhizosphere AM to improve the root activity， the exogenous AM fungi can also regulate the nutrient contents in the rhizosphere soil，increase the contents of total glomalin and easily extracted glomalin，increase the abilities of P. polyphylla var. yunnanensis to absorb the available N，P and K，and increase the enzyme activities in the rhizosphere soil， improve the microbial community structure， and improve the rhizospheric environment of P. polyphylla var. yunnanensis by increasing the bacteria/fungi and bacteria/actinomycetes quantity ratios and reducing the fungi/actinomycetes quantity ratio. Conclusion:Different AM fungal treatment groups had certain effects on the physicochemical properties and microbial community structure of the rhizosphere soil of P.polyphylla var. yunnanensis，which provided a technical basis for the cultivation of P. polyphylla var. yunnanensis.
