摘　　要：以来自重庆市唐家桥污水处理厂的生污泥,经不同处理的干化污泥、消化污泥和堆沤污泥为材料,研究对一串红、孔雀草和矮牵牛生理特性的影响。结果表明:施用污泥对促进3种花卉生长和提高品质作用明显。污泥施用量对3种花卉生物特性的影响显著。供试污泥施用量分别为一串红50%(质量百分比)、矮牵牛和孔雀草37.5%对促进3种花卉生长的效应最大。污泥种类的影响不显著,但是在3种污泥之间堆沤污泥有机质含量和阳离子交换量最高,而且其盐分含量最低,相对来说对土壤的改良更显著,也更加安全。With air-dry sludge, digested sludge and composted sludge which processed by draft sewage sludge from Chongqing Tangjiaqiao Wastewater Treatment Plant as materials, effects of physiological parameters of three flowers, including Salvia Splendens, Tagetes Patula, Petunia Hybrida. The results showed that. The three sludges could improve physiological parameters and quality of the three flowers. Effects of physiological parameters of three flowers on dosage of sludges was significant. Salvia Splendens grow best when the dosage of sludges at 50% （mass percent）, Tagetes Patula and Petunia Hybrida grow best at 37.5 %. Effects of physiological parameters of three flowers on variety of sludge was not significant, but the organic content and CEC of composted sludge were highest, and the EC was lowest, so the composted sludge was better for soil improvement and safer than other sludges.
