干旱胁迫对冷季型草坪草地上部影响的研究

RESEARCH FOR INFLUENCE TO THE PART OUT OF EARTH OF TURFGRASSES OF COLD SEASON STYLE BY DROUGHT STRESS

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 author made a systematic observation to the influence of qualities of the out look of five kinds of cold seasons style under drought stress by soil water potential (SWP). Evaporate rate (ER), leaf growth rate (LGR). related leaf water content (RLWC). Leaf water potential(LWP), and studied the physiological change of water of turfgrasses under drought stress, and provided the theoretic basis for lurfgrass selection and its scientific management in dry area.$$$$
