- 摘要:
- 选择不同的混播草坪，草地早熟禾∶高羊茅∶多年生黑麦草=6∶2∶2、草地早熟禾∶紫羊茅∶细弱翦股颖=5∶4∶1，以草地早熟禾单播为对照，对这3种供试草坪进行充分和限制灌水试验。结果表明：2种不同的混播草坪其蒸散量不同，且与单播草地早熟禾的蒸散量差异显著（P<0.01）；在不同水分条件下各供试草坪的蒸散量均表现为：草地早熟禾∶紫羊茅∶细弱剪股颖=5∶4∶1>草地早熟禾∶高羊茅∶多年生黑麦草=6∶2∶2>单播草地早熟禾，2种混播草坪在保证其较高观赏价值和稳定性的前提下耗水量要比单播草地早熟禾多。
- 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.
