城市污泥堆肥用作花卉栽培基质的效果评价

Effect Evaluation of Municipal Sludge Compost Used as Floriculture Substrate

通过花卉栽培试验，考察了污泥堆肥用作花卉栽培基质的效果。结果表明：与施用化肥和不施肥相比，添加污泥堆肥可以促进袖珍椰子、富贵竹和撇金竹三种花卉的生长，并能提高其生物量和改善花卉的观赏品质。综合评价结果表明，在栽培基质中污泥堆肥的加入比例以25％～50％为宜。此外，污泥堆肥还可以改善基质的通气性、保水性和养分供应能力。

Through the floriculture experiment, the effect of municipal sludge compost used as the floriculture substrate was investigated. The results show that compared with the experiments with and without fertilizer, municipal sludge compost can promote the growth of Chamaedorea elegans, lucky bamboo and PhyUostachys sulphurea, increase their biomass and improve the ornamental quality. The additional proportion of municipal sludge compost into the substrate should be 25% to 50%. In addition, the sludge compost can improve the ventilation, water-holding capacity and nutrient supply capacity of the substrate.
