中文摘要	通过大田试验,分析土壤蒸发、作物蒸腾和总耗水的变化。结果表明,葡萄园土壤蒸发、作物蒸腾和总耗水平均日变化均呈钟型曲线;全生育期葡萄园耗水420mm,其中土壤蒸发量193mm,占46%,作物蒸腾量227mm,占54%;日均总耗水、土壤蒸发和作物蒸腾分别为2.32、1.08、1.24mm/d。微型蒸渗仪结合茎流计测定的耗水与涡度相关仪测定的在小时和日尺度上均比较接近,差异不足10%;灌溉和降雨使土壤蒸发加剧,作物蒸腾对灌溉的响应滞后于土壤蒸发,而对降雨无明显响应。
英文摘要	The variations of soil evaporation,crop transpiration and crop water consumption were analyzed in the vineyards through field experiments.The results showed that the diurnal variations of soil evaporation, crop transpiration and crop water consumption changed withcampaniformcurves.The total crop water consumption was 420mm,of which soil evaporation was 193mm(46%)and crop transpiration was 227mm (54%).The total crop water consumption intensity,soil evaporation intensity and crop transpiration intensity were 1.08,1.24and 2.32mm/d,respectively.The sum of evaporation and transpiration by Micro-lysmeter and Sap flow system was close to the crop water consumption by the Eddy covariance system in vineyard in hour and day scales,whose error was less than 10%.Soil evaporation was aggravated by irrigation and precipitation,and the response of crop transpiration to irrigation was earlier compared to the response of soil evaporation,but there was no obvious response to precipitation.
