摘　　要：在翦股颖的传统壤土,USGA半改良和全改良3种坪床中,用树叶、塑料薄膜、草帘、果岭棉被4种覆盖材料在冬季进行覆盖处理,对各坪床结构的草坪盖度、草坪颜色、土壤含水量、地下植物量进行比较。结果表明,树叶覆盖后的翦股颖草坪盖度最高,草帘和塑料薄膜次之,果岭棉被最差。草坪颜色草帘覆盖的最高,其次为塑料薄膜和树叶,最次为果岭棉被;地下植物量果岭棉被>树叶>草帘>塑料薄膜;保水性能壤土>全改良>半改良。Three kinds of seed bed materials（loam soil,semi-amended and fully amended seed bed）covered with 4 kinds of covering materials（tree leaves,plastic film,straw blanket and green quilt） in winter were used to study the overwintering of bentgrass by measuring the turf coverage,turfgrass color,soil moisture and underground phytomass.The result indicated that the coverage of turf covered with tree leaves was the highest,and it was followed by straw blanket,plastic film and green quilt.For turfgrass color,the straw blanket treatment was the best,and followed by plastic film,tree leaves and green quilt.And for underground phytomass,the order was green quilt tree leaves straw blanket plastic film.The order of water holding performance was loam soil semi-amended fully amended.
