Abstract:
Objective:To clarify the effect of the arbuscular mycorrhizal （AM） fungi on the rhizosphere soil nutrient content，AM fungi infection rate and total rhizome saponins content of Paris polyphylla var. yunnanensis under symbiosis culture. Method:The changes in the root AM fungi infection rate，rhizosphere soil nutrient content，total rhizome saponins content of P. polyphylla var. yunnanensis and the relationship of the rhizosphere soil factors，the infection rate and the total rhizome saponins content after AM fungi inoculation were analyzed by the method of combining room temperature pot inoculation and data analysis. Result:As compared with the CK group，the root AM fungi infection rate of the AM inoculation group was significantly enhanced （P<0.05），the content of easily extractable glomalin，total glomalin，and total nitrogen increased significantly，while available potassium content and pH significantly decreased. After inoculation with AM fungi，the contents of total phosphorus，available phosphorus，available nitrogen，ammonium nitrogen，nitrate nitrogen，available potassium，and organic matter in the rhizosphere soil of P. polyphylla var. yunnanensis showed significant differences as compared with the CK group. The soil nutrient status was improved，and the total saponin content in the rhizome of P. polyphylla var. yunnanensis was increased. Conclusion:Inoculation with AM fungi can improve the rhizosphere soil nutrient status of P. polyphylla var. yunnanensis，promote the nutrient transformation in the rhizosphere soil，promote the growth of P. polyphylla var. yunnanensis，and improve the quality of medicinal herbs.
