摘　　要：研究了6种肥料和2个不同施肥时期对翦股颖生长速度、绿期、地下生物量、密度及越冬率指标的影响,结果表明,各施肥处理均能促进草坪草初期生长,延长草坪绿期,美国Scotts和雷力果岭专用肥绿期显著高于其他处理(P<0.05);地下生物量和越冬率,美国Scotts果岭专用肥显著高于其他肥料(P<0.05);秋季施用尿素会导致草坪徒长,枯草层增厚,延迟返青;北京地区秋末翦股颖较适宜的施肥时间为10月20日左右。Thi＇s experiment was conducted to study the effects of the six kinds of fertilizer and two different fertilization dates on bentgrass growth rate, green stage, underground biomass, density and winter rate, in order to provide some references to golf course. The results showed that all the fertilization treatments promoted the growth of the bentgrass, and prolong its green stage; The United States Scotts and Leili special fertilizer of greens have significantly better effect on green stage than the others（P〈0.05 ）; The United States Scotts Fertilizer were more effective than other treatments （P〈0.05） especially in underground biomass and winter rate; Application of urea in fall led to the lawn leggy, thick layer of hay, delayed regreen date; The best time to fertilize to bentgrass in Beijing areas is around October 20.
