Abstract:
With different mixed seeding turfgrass Poa pretensis∶Festuca arundinacea∶Lolium perenne=6∶2∶2,Poa pretensis∶Festuca rubra∶Agrostis tenuis Colonial Bentgras=5∶4∶1, and with Poa pretensis unicast as control，the three kinds of turfgrass on experiment in full irrigation and limited irrigation conditions were studied.The results showed that the two different mixed seeding turfgrass had different ET，and the ET had significant difference with unicast Poa pretensis (P<0.05);The ET of three turfgrass under different moisture conditions sequence was Poa pretensis∶Festuca rubra∶Agrostis tenuis Colonial Bentgras=5∶4∶1>Poa pretensis∶Festuca arundinacea∶Lolium perenne=6∶2∶2>unicast Poa pretensis；In the premise of ensuring its high ornamental value and stability,the two mixed seeding turfgrass had more water consumption than unicast Poa pretensis.
