摘　　要：通过温室水培,以草地早熟禾‘Midnight’(抗旱品种)和‘Brilliant’(不抗旱品种)为试材,研究了修剪条件下水分胁迫和磷处理对草地早熟禾草坪质量的影响。结果表明:无论水分胁迫与否,随着外源磷加入量的增加,草地早熟禾草坪的颜色质量、一致性和分蘖数均显著增加。水分胁迫使同等磷处理草坪颜色质量、一致性和分蘖数下降,抗旱品种‘Midnight’在水分胁迫下的颜色质量、一致性和分蘖数高于不抗旱品种‘Brilliant’。Through hydroporie greenhouse culture, taking Poa pratensis L. ＇ Midnight＇ （drought-resistant） and ＇ Brilliant ＇ （not drought-resistant variety） as the test materials,the effects of water stress and phosphorus on the turf quality of Poa pratensis L. under hydroponic culture and mowing conditions were studied. The results showed that whether there was water stress or not,color quality, uniformity quality and tilling number were increased significantly with the increase of exogenous phosphorus addition. Color quality, uniformity quality and tilling number were decreased significantly by water stress at the same phosphorus treatment. Color quality, uniformity quality and tilling number of ＇ Midnight＇ was better than that of ＇Brilliant＇ under water stress.
