摘　　要：采用单因素随机区组试验的方法,研究了金华市污水厂污泥堆肥对黑麦草生长和对重金属的吸收及富集的影响。结果表明,施用量以1 kg/m2和2 kg/m2的两个处理为宜,当年的产草量比对照分别增加了22.6%和27.8%;施用污泥黑麦草植株地上部组织重金属元素Pb、Cd和Cu的含量与对照相比无显著差异,Zn的积累量增多,重金属含量均未超过植物中的平均含量,施用污泥未对黑麦草造成重金属污染。Adopted plot experiment to study the effect of sludge compost on Lolium perenne L. growth and heavy mental accumulation through using the sewage sludge from Jinhua wastewater treatment plant. The results showed that the above ground biomass at the rate of 1. 00 to 2. 00 kg/m^2, significantly increased of Pb, Cd, Cu was no significantly difference, while However, the above ground heavy metal element content was increased when sewage sludge was applied by 22. 6% to 27.8%. Meanwhile, the content the content of Zn was accumulated greatly was not more than the average concentration in whole plant, no heavy metal contamination caused by application of sewage sludge.
