城市污泥堆肥对草坪草生长的影响

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。

Effects of Urban Sludge Composting on Growth of Lawn Grass

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.
