In order to explore the effect of different arbuscular mycorrhizal fungal inoculants on different nutrient elements of soil and Paris polyphylla var. yunnanensis,it provides a reference for the development of P. polyphylla var. yunnanensis biological bacterial fertilizer.In this study,the pot inoculation experiment was conducted to inoculate different arbuscular mycorrhizal fungi inoculants during the P. polyphylla var. yunnanensis,the contents of nitrogen (N),phosphorus (P),potassium (K),calcium (Ca) and magnesium (Mg) in P. polyphylla var. yunnanensis and soil were determined by the Kjeldahl method,vanadium-molybdenum yellow colorimetric method,the deboiling method with sulfuric acid and perchloric acid and atomic absorption spectrometry.The results showed that the absorption and accumulation of nutrients elements in different parts of Paris polyphylla var. yunnanensis and soil in different growth stages after treatment with different arbuscular mycorrhizal fungal inoculants.S8 treatment could increase the content of N,P in new rhizomes and leaves (up to 6.289 g/kg) and Ca in different parts of Paris polyphylla var. yunnanensis.The content of Ca in leaves was the highest (40.323 g/kg).The content of Mg in new rhizome was 28.142 g/kg,but the content of N,P,K and Mg in different am treatment groups did not change significantly.However,the content of Ca in soil increased in different degrees,and the effect of S8 treatment group was better,up to 125.734 g/kg.Correlation analysis showed that there was a positive correlation between N and Ca,Mg in old tuber,and between Ca and Mg in the old tuber.Ca in old tuber was negatively correlated with Ca,Mg in soil.N and P,Mg in new rhizome were positively correlated with P and K,while Ca and K in soil were negatively correlated with Mg in soil.In conclusion,different AM fungal inoculants could affect the absorption and accumulation of nutrient elements in Paris polyphylla var. yunnanensis and soil,among which S8 treatment group (G. albida,G.gigantea,S. calospora, R. fulgida,R. intraradices,C. claroideum).It can be used as an excellent strain of biological fertilizer of P. polyphylla var. yunnanensis.
