【摘要】 以狗牙根(Cynodon dactylon)天堂草328为植物材料,比较了煤渣、锯木屑、污泥、垃圾土和蘑菇土这5种废弃物基质分别对无土草皮质量性状、生产成本和环境效益3个方面的影响。结果表明,狗牙根可以显著降低废弃物中的铜、锌含量(P<0.05);污泥处理的颜色、盖度和地上生物量显著高于其他处理(P<0.05),污泥、煤渣处理的总生物量和根系生物量显著高于其他处理(P<0.05),各处理之间新鲜度差异不显著(P>0.05),综合各项坪用性状指标分析,这5种基质的优劣顺序为污泥(δ污泥=0.885)>蘑菇土(δ蘑菇土=0.674)>锯木屑(δ锯木屑=0.598)>垃圾土(δ垃圾土=0.550)>煤渣(δ煤渣=0.543)。上述结果说明污泥最适合作为狗牙根无土草皮的生产基质。更多还原

【Abstract】 An experiment was carried out determine the effect of coal cinder,sawdust,municipal sludge,waste compost and mushroom soil on the sod quality character,operating costs and environment benefit of sowing Bermudagrass(Cynodon dactylon) named Tiantang 328.The results of this study indicated that Bermudagrass obviously reduced the Cu and Zn content,and the sod color,cover and above-ground biomass in municipal sludge treatments was better or significantly higher than that in other four treatments(P< 0.05).The total biomass and root biomass in the municipal sludge and coal cinder were significantly lower or higher than that in other treatments(P<0.05).The sod freshness was not significant among five treatments(P>0.05).The comprehensive estimation showed that five waster soilless medium in the order: municipal sludge(δmunicipal sludge=0.885)>mushroom(δmushroom=0.674)>sawdust(δsawdus =0.598)>waste compost(δwaste compost=0.550)>coal cinder(δcoal cinder=0.543),suggesting that the municipal sludge was the best soilless medium of the bermudagrass sod.更多还原
