摘　　要：以金华市某污水处理厂污泥为研究对象,研究污泥堆肥对凤仙花生长及土壤的影响。结果表明,污泥堆肥不同处理与对照相比,污泥堆肥60%+园土20%+炉渣20%,施用效果最好。污泥土地利用提高了土壤中N、P及有机质含量,土壤理化性质有明显改善,但同时也增加了土壤中Cd元素的含量,土壤Pb、Cu、Zn含量变化甚微。The effect of sludge compost on Impatiens balsamina L. growth and soil environment were researched through using the sewage sludge from JinHua wastewater treatment plant. The results showed that the treatment of 60% sludge compost＋20% garden soil＋20% slag was notably promote the nutritional growth of Impatiens balsamina and application of sewage sludge compost could increase the contents of N, P and organic matter in soil. Howe er, after application of sweage sludge compost, Cd contents also increased compared with the control,while the contents of Pb, Cu and Zn in soil showed no significant change.
