Abstract:
Objective:To investigate the effects of arbuscular mycorrhiza（AM） fungi inoculation on the rhizosphere soil of Paris polyphylla var. yunnanensis under field conditions，so as to provide a reference for the standardized cultivation and development of high-quality varieties of P. polyphylla var. yunnanensis. Method:The effects of inoculation with mycorrhizal fungi on the rhizosphere soil structure of P. polyphylla var. yunnanensis were observed through a combination of small-scale field inoculation test and laboratory analysis. Soil indexes were determined by soil agrochemical methods. Result:The treatment groups inoculated with exogenous AM fungi showed a regulatory effect on the infection rate and intensity of AM fungi infection in the root system of P. polyphylla var. yunnanensis. After treatment with AM fungi，the soil pH was basically not affected，and the contents of organic matter，available nitrogen，available phosphorus，and available potassium increased. Moreover，the number of fungi decreased，the number of bacteria and actinomycetes increased，and soil enzyme activities increased. The results of correlation analysis showed that there was a significant positive correlation among the soil physical and chemical indexes，especially the bacterial number and the three types of phosphatases showed extremely significant correlation （r=0.849，0.800，0.804，P<0.01）. Conclusion:The application of the two mixed fungicides could increase the number of microorganisms and enzyme activities in the rhizosphere of P. polyphylla var. yunnanensis， and there was a certain synergy effect among the soil factors. Among the three field trials，the effects in Anshun，Guizhou and Wanzhou，Chongqing were more ideal，which provided a theoretical and practical basis for large-scale promotion of P. polyphylla var. yunnanensis in the field.
