对５ 种冷季型草坪草在持续干旱胁迫过程中， 土壤水势 （ Ｓ Ｗ Ｐ） 对蒸发率 （ Ｅ Ｔ）、叶片生长率 （ Ｌ Ｇ Ｒ）、叶水分相对含量 （ Ｒ Ｌ Ｗ Ｃ）、叶水势 （ Ｌ Ｗ Ｐ） 及草坪外观质量的影响进了系统观察，探讨了草坪草在干旱胁迫下的水分生理变化。为干旱或缺水地区选育草坪和草坪的科学养护管理提供理论依据。
The effects of soil water potential (S W P) on E T, L G R, R L W C, The effects of leaf water potential (L W P) and lawn appearance quality were systematically observed, and the physiological changes of turfgrass under drought stress were discussed. Provide a theoretical basis for the scientific conservation and management of lawn and lawn selection in arid or dry areas.
