摘　　要：通过工程应用试验,研究了污泥堆肥产品作为草坪基质材料时对草坪和基质质量的影响。结果表明,污泥堆肥产品施用量的增加可显著提高草坪草的单株质量和分蘖数,增加叶宽,但对成坪时间有一定的延迟效应;同时,移栽后的新根长度和草坪绿期都显著增加,基质密度降低,持水性得到改善。The effect of sewage sludge compost product used as lawn substrate on lawn and sub- strate quality was investigated by engineering application test. The results indicate that the increase of sewage sludge compost application amount can increase weight per plant, tiller and leaf width, while the finished time of lawn is delayed by sewage sludge compost application. Transplanted new-root length, green period and water holding porosity of substrate are remarkably improved with increase in sewage sludge compost application amount, meanwhile bulk density of the substrate is decreased.
