摘　　要：对翦股颖果岭草坪在统一低灌溉频率(30d一次)下,冬季用果岭棉被、草帘、树叶、塑料薄膜四种不同的覆盖材料进行覆盖,比较不同覆盖物对土壤含水量、土壤温度、草坪外观质量及地上和地下生物量的影响。结果表明:四种覆盖处理较对照均表现出不同程度的保水保温性能,其中草帘和树叶的保温效果最佳,树叶和塑料薄膜的保水性能最好;揭开覆盖物后草帘覆盖的草坪外观质量最高,树叶和塑料薄膜次之,果岭棉被较差;覆盖后地下总根量依序为果岭棉被>草帘>树叶>塑料薄膜。Under low irrigation frequency （30d each time）, the bentgrass （Agrostis stolonifera ） green was covered with green quilt, straw matting, leaves and plastic film in winter. The influence of these four kinds of materials on moisture content, soil temperature, turf appearance quality, underground biomass and aboveground biomass was studied. It indicated that the ability of water retention and heat preservation of green increased in difference extent under all four kinds of treatments. Heat preservation under straw matting and leaves was the best, water retention under leaves and plastic film was the best. Turf appear ance quality was the best under straw matting, and then leaves and plastic film. Green quilt had poor ability to improve turf appearance quality. Underground biomass under four kinds of treatment showed that green quilt〉straw matting〉leaves〉plastic film.
