摘　　要：为确定城市污泥堆肥对观赏植物生长发育的影响,以添加不同比例的城市污泥堆肥为栽培基质,以园土为对照,对观赏植物百日草的生长发育情况进行了试验研究。结果表明,城市污泥堆肥对促进百日草的生长发育作用明显,最适合百日草栽培的污泥堆肥基质配比为:V(污泥堆肥)∶V(珍珠岩)∶V(河沙)=2.5∶1.5∶1.0。The growth and development of Zinnia elegans was studied to determine the effect of sewage sludge compost on the growth and development of ornamental plants,by adding different proportion of sewage sludge compost as the cultivation substrate and garden soil as the control.The results showed that sewage sludge compost had an obvious effect on the growth and development of Zinnia elegans.The optimal substrate ratio for the cultivation of Zinnia elegans was sewage sludge compos-perlite-river sand(2.5∶1.5∶1.0).
