摘      要：Objective:The moisture content in the soil directly affects the yield and quality of Panax notoginseng,especially at the age of three years ***,the suitable moisture for the growth of *** is *** this study,the effects of different soil moisture on the growth of *** were ***:Four different water treatments(0.45 field capacity(FC),0.60 FC, 0.70 FC, and 0.85 FC) were set up in Shilin County,Yunnan Province,*** water consumption and daily dynamic of water consumption were determined daily(from April 21 to October 18,2012),and the daily dynamic of water consumption under different weather conditions(sunny and rainy) was *** transpiration coefficient and water use efficiency were calculated through dry matter accumulation and total water *** of saponins of roots of *** were analyzed by HPLC after treated,and the soil moisture content suitable for the growth of *** was estimated by regression fitting of the active ingredient accumulation and the soil moisture ***:The water consumption of 0.85 FC,0.70 FC,0.60 FC and 0.45 FC were 2.89,3.68,3.37 and 2.73 kg/plant per day,*** water consumption of *** from June to August was greater than other *** daily dynamic of water consumption on sunny days and sunny days after rain showed a double peak feature,and it showed a single peak feature on rainy *** water uses efficiency(WUE) of 0.85 FC,0.70 FC,0.60 FC and 0.45 FC were 2.51,3.32,4.59,3.39 gDW/kg H_(2)O,*** increase of soil moistu re content would reduce the WUE of *** *** the increase of soil water content,the content of notoginsenoside R_(1) and ginsenoside Rg_(1) did not change significantly,while the content of ginsenoside Rb_(1) and Rd showed a decreasing ***:Soil moisture content significantly affected the water consumption of ***,and when it was 56.4% of the maximum water h
