%X This paper studied the stem sap flow of grape in arid oasis region of Shiyang River basin under conventional drip irrigation(CDI),alternate drip irrigation(ADI),and fixed drip irrigation(FDI),and its relationships with meteorological conditions and soil moisture content.The results showed that the stem sap flow of grape had an obvious day-night rhythm synchronous with solar radiation,and was significantly higher under CDI than under ADI and FDI during new branch growth and flowering stages.Solar radiation and air temperature were the main meteorological factors affecting the hourly sap flow,and the daily stem sap flow had linear relationships with daily air temperature and wind speed.The correlation coefficients between the stem sap flow and the meteorological factors ranked in the order of CDI>ADI>FDI.There was a significant correlation between daily stem sap flow and reference crop evapotranspiration(ET0).Compared with CDI,ADI could save 50% of irrigation water while the stem sap flow only reduced by 6.56%,and an obvious compensation effect between stem sap flow and hydraulic conductivity was observed.
