[Abstract] Objective ： To explore the influence on AM fungi infection rate and medicine quality of Pinellia ternate in the condition of three soil impact factors. Method ：Set the orthogonal test of three factors and levels. Determinate the AM fungi infection rate in early stage of mature & stage of mature of P. ternata， and the water content， water soluble extract， butanedioic acid content and alkaloid content of P. ternata tuber that be harvested also had be determinated. Result and Conclusion ：With the P levels to 30 mg·kg-1 and 90 mg·kg-1， AM fungi infection was the best when mixed inoculated of EM. Microbial agent inoculated played a decisive role in P. ternata growth and physiological activity， secondary influenced factor was P concentration， and the water stress was the minimal impact. Mixed inoculated of AM fungi and EM treatment with the low P levels(30，90 mg·kg-1) proved better effect on enhancing the water extract content， anedioic acid and alkaloid content， while decreasing the water contents of P. ternata tuber.
