考察了城市污泥堆肥用于草坪基质的生物与环境效应.结果表明,施加污泥堆肥可改善草坪基质的理化性质,显著增加草坪草的叶绿素含量,促进其对氮、磷和钾的吸收,提高草坪草的生物量,可使草皮卷的质量最多减轻29%;从短期来看,在施加污泥堆肥的草坪基质中并未发现明显的盐分和重金属累积现象.将污泥堆肥用于草坪基质是污泥资源化利用的一条新途径.

The biological and environmental effects of municipal sludge compost used as turf sub-strate were investigated. The results indicate that the municipal sludge compost can improve the physico-chemical properties of substrate, increase chlorophyll content in the turfgrass, accelerate the uptake of ni-trogen, phosphorus and potassium and improve the biomass of the turfgrass. The weight of turf with mu-nicipal sludge compost can be reduced by maximally 29% compared with control. The residual accumula-tion of salinity and heavy metals in the substrate is not significant during a short period. The use of mu-nicipal sludge compost as turf substrate is a new way for disposal of municipal sludge.
