摘　　要：以5种混播草坪为试材,通过水量平衡法研究了5种混播草坪的蒸散量,比较了蒸腾耗水规律及节水潜力,并计算了5种混播草坪的坪草系数。结果表明：充分灌水条件下的蒸散量为混播Ⅴ（456.20mm）〉混播Ⅲ（412.04mm）〉混播Ⅰ（397.38mm）〉混播Ⅱ（378.95mm）〉混播Ⅳ（363.17mm）,限制灌水时的蒸散量为混播Ⅳ（347.87mm）〉混播Ⅴ（329.99mm）〉混播Ⅱ（316.23mm）〉混播Ⅰ（310.97mm）〉混播Ⅲ（279.26mm）;5种混播草坪节水潜力从大到小依次为混播III（132.78mm）〉混播V（126.21mm）〉混播I（86.41mm）〉混播II（62.72mm）〉混播IV（15.30mm）;5种混播草坪的坪草系数介于0.93～1.52之间。With five kinds of mixed-seeding turfgrass as test materials,the evapotranspiration rate were studied with water balance method,the evapotranspiration regulation and water saving potential were compared,and the turfgrass crop coefficients were calculated.The results showed that under full irrigation condition the evapotranspiration of five mixed seeding turfgrass showed that TurfⅤ（456.20mm）〉TurfⅢ（412.04mm）〉TurfⅠ（397.38mm）〉TurfⅡ（378.95mm）〉TurfⅣ（363.17mm）,when irrigation was limited,TurfⅣ（347.87mm）〉TurfⅤ（329.99mm）〉TurfⅡ（316.23mm）〉TurfⅠ（310.97mm）〉TurfⅢ（279.26mm）;the water saving potential of the five mixed turfgrass was Turf Ⅲ（132.78mm）〉Turf Ⅴ（126.21mm）〉Turf Ⅰ（86.41mm）〉Turf Ⅱ（62.72mm）〉Turf Ⅳ（15.30mm）;the turfgrass crop coefficients of five kind mixed seeding turfgrass ranged from 0.93 to 1.52.
