摘　　要：为使城市生活污泥得以无害化、资源化综合利用,研究了经无害化处理的生物干化污泥对马尼拉草坪生长状况和土壤效应的影响。结果表明,随着生物干化污泥施用量的增加,马尼拉草叶绿素含量和生物量逐渐提高,但施用量超过1 250 g.m-2后,对马尼拉草的促进作用不再显著。生物干化污泥对马尼拉草坪具有较好的培肥效应,草坪土壤脲酶、蔗糖酶、过氧化氢酶活性显著提高。施用生物干化污泥还可提高土壤全氮、全磷、无机氮和速效磷含量,施用后不会造成土壤重金属污染。在园林绿地草坪使用,只要将施用量控制在1 250 g.m-2以下,是基本安全的,这为生物干化污泥在园林草坪上的推广应用提供科学依据。To enhance the utilization of detoxified city sewage sludge,the effect of biological drying sludge on growth and environmental effect of Manila lawn（Zoysia matrella）were studied in this paper.The results indicated biological drying sludge showed good effect on the growth of the Manila and the improvement of soil fertility.It showed that dramatic enhancement of Manila＇s chlorophyll and biomass with increasing application rates of biological drying sludge.However,more than 1 250 g·m-2 application on the grass,the promotion of Manila were no longer significant.At the same time,there was observable dramatic improvement of the activities of soil urease,sucrase and catalase.Biological drying sludge proved the total and effective nutrient contents of N and P in soil,and not caused pollution of soil heavy metals.Green lawn in the garden of the use of biological drying sludge,as long as the annual application rate control below 1 250 g·m-2 was basic security.These provide experimental basis for the promoting the application of biological drying sludge to gardens and green lands.
