Abstract:
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 Turf Ⅴ(456.20 mm)>Turf Ⅲ(412.04 mm)>Turf Ⅰ(397.38 mm)>Turf Ⅱ(378.95 mm)>Turf Ⅳ(363.17 mm)，when irrigation was limited,Turf Ⅳ(347.87 mm)>Turf Ⅴ(329.99 mm)>Turf Ⅱ(316.23 mm)>Turf Ⅰ(310.97 mm)>Turf Ⅲ(279.26 mm)；the water saving potential of the five mixed turfgrass was Turf III（132.78 mm）>Turf V（126.21 mm）>Turf I（86.41 mm）>Turf II（62.72 mm）>Turf IV（15.30 mm）；the turfgrass crop coefficients of five kind mixed seeding turfgrass ranged from 0.93 to 1.52.
