摘　　要：在遮荫胁迫下,草坪草的解剖结构、形态结构、营养吸收积累及生理活动等都会发生一系列变化。对遮荫条件下草坪草光合作用、水分生理、营养生理等主要生理反应的研究进行总结和分析,提出应当从整个草坪构成和草坪草构件的角度对其机理进行深入的研究,改善草坪草的耐遮荫胁迫能力,不仅要提高建植技术和经营管理水平,更应该加速对耐荫草种或品质的选育,加强对野生种质的开发与研究是解决当前草坪草耐荫性差的根本出路。When shaded, turf grass＇ s anatomic structure, morphological structure, assimilation of nutrition and other physiological activities will change a lot. This article summarizes and analyses turf grass＇s main physiological reactions such as photosynthesis, water metabolism, and nutrient physiology and so on under shade. Investigating the turf structure and the components of grass is an appropriate method to study its shade tolerance mechanism. In order to increase the shade tolerance of the turf grasses, we should not only improve planting and managing, but also accelerate breeding. So, exploiting and studying wild grass resources is the essential way to solve the shading problem.
