摘　　要：文章主要对城市污泥好氧发酵产物用于草坪基质后,对草坪建植指标的影响,包括萌发密度、根重和盖度进行了分析。结果表明施用污泥发酵物对草坪萌发密度和根重无显著影响。盖度指标上,高施用量污泥发酵物表现出显著的提升效应。污泥发酵物的施入对成坪后基质的抗撕裂强度有一定程度降低,但对运输造成的基质完整性并无显著负面影响。Effects of applying composted sewage sludge on the sods indexes including germination, root weight and coverage were investigated. Results indicated that composted sludge has no significant effect on germination and root weight. However, coverage was increased by high composted sludge application rate. Meanwhile, input of composted sludge decreased substrate tear strength, hut no significant negative effect on integrity by short distance transportation.
