摘　　要：[目的]实现城市污泥的废物利用。[方法]研究城市污泥、菇渣、米糠和药渣的不同配比混合基质对蓝猪耳生长的影响,并比较蓝猪耳在不同的无土栽培基质和在常规栽培基质中生长指标的差异。[结果]在栽培过程中不施肥的条件下,无土栽培基质中蓝猪耳的各项生长指标均优于常规栽培基质。在营养阶段,基质3(城市污泥含量40%)和基质6(城市污泥含量70%)中蓝猪耳的生长状况较优;在开花期,处理组各项检测指标多数优于对照组,其中基质3和基质6蓝猪耳的花朵数较多。[结论]该研究为城市污泥的环保资源化利用提供参考。[Objective]The research aimed to achieve waste utilization of municipal sludge.[Method]This experiment studied the effect of different proportions of mixed substrates including municipal sewage sludge,mushroom residue,rice bran and herb residues on growth of Torenia fournieri and compared the growth indexes of T.fournieri under the different soilless culture substrate situations and under conventional culture substrate situations.[Result]Under the condition of no additional fertilization during the cultivation process,the growth indexes of the T.fournieri in the soilless culture substrate were better than those in the conventional culture substrate.In vegetative growth stage,the growth status of T.fournieri in substrate 3(the municipal sewage sludge content of 40%)and in substrate 6(the municipal sewage sludge content of 70%)was better.In floral blossom,most of examination indexes of the treatment groups were better than the control groups.And the number of flowers in substrate 3 and in substrate 6 was better.[Conclusion]This study provides a reference for the environmental resource utilization of municipal sewage sludge.
