摘　　要：对生活垃圾堆肥为基质无土草皮与园土基质草皮的相关生长参数进行了比较,结果表明,同种草坪植物垃圾堆肥基质与园土基质草皮相比,除早熟禾和匍茎剪股颖的须根数及高羊茅和黑麦草的单株地上净光合量外,其他生长指标差异不大(P>0.05),草皮绿度差异也不大。抗拉强度主要取决于草皮铺网的自身特性,各草皮抗拉强度约为10kg。4种草坪植物草皮根系与基质、铺网的固着状态相对优劣次序为:高羊茅>黑麦草>早熟禾>本特。草皮铺坪应用结果表明,2种基质草皮间存在着草种与基质、铺网的生态协同性差异。从草皮铺坪应用指标看,铺坪后草坪植物生长状况与草皮培植时生长状况密切相关,一般培植时生长状况好,则铺坪时生长状况也好。垃圾堆肥草皮铺坪后,具有较好的色泽效应,其他应用性能也较为理想。综合性能分析,以生活垃圾堆肥为基质的无土草皮性能符合草皮培植技术性能要求,有些性能还明显优于园土基质草皮。A comparative study was made on the growth parameters of sod establishment system with municipal solid waste compost and garden soil as the media. The results showed that the fibre root numbers of Poa pratensls and Agrostis stolonifera were significantly fewer on compost than on soil medium, and the single plant＇ s net primary production of turfgrass for Festuca arundinacea and Lolium perenne was significantly higher on compost than on soil medium. For the same cultivar, there was little difference （ P 〉 0. 05 ） in the other growth parameters between the two media. The tensile strength of sod was primarily depended on sod netting properties, being about 10 kg for all of test sods. For the four turfgrass cuhivars, the sessile state of sod roots with medi- um and netting had the order of F. arundlnacea 〉 L. perenne 〉 P. pratensis 〉 A. stolonifera from strong to weak. In sod laying, there were differences in the ecological cooperativity of cultivar, medium, and netting between the sods on the two different media. The turfgrass growth after sod laying was closely relevant to that in sod culture, i. e. , the better in sod culture stage, the better in sod laying stage. After sod laying, the turfgrass with compost as the media had much better lustrous effect. The synthetical properties of compost medimn sod were accorded with sod culture requirement, and some properties were better than those of soil medium sod.
