［目的］研究污泥堆肥对草坪草生长的影响，找出降低草坪生产成本的新途径。［方法］用城市污泥种植草坪草，6个月后，测定其生物量，草坪高度及叶绿素含量。［结果］堆肥作基质使草坪草获得了良好的生物效应，5%~10%堆肥施用比例范围内，随着堆肥施用量的增加，草坪草的地上生物量增加，叶片叶绿素含量增加，草坪的外观颜色明显优于对照处理。［结论］城市污泥用做草坪基质，使草坪草获得了良好的生物效应，既可以解决城市污泥的出路，又可以降低草坪的生产成本。 ［Objective］ To study the effects of sludge composting on the growth of lawn grass and find new ways for reducing production costs of lawn. ［Method］ Urban sludge was used as composting to plant lawn grass. After cultivation for six months, the biomass, turf height and chlorophyll content were then measured. ［Result］ The aboveground biomass of lawn grass and leaf chlorophyll content increased with the increase of sludge composting fertilizer within the range of 5%-10%, and the lawn exterior color was much better than that of the control. ［Conclusion］ Lawn grass show good biological effects through using urban sludge composting as lawn medium. It can reduce the production costs of lawn grass. _
