疏浚底泥的园林绿化应用

Horticultural Application of Dredged Sediment

疏浚底泥具有陆地土壤的基本理化性质,富含植物生长所需的各种营养物质,可以用作土壤改良剂或人造土壤,应用于园林绿化。底泥用作土壤改良剂可以改善土壤理化性质,促进植物生长。底泥用作人造土壤应用于园林绿化的客土置换,可以避免因客土置换引起的采土区水土流失问题,且易实现质量控制,是底泥园林绿化应用的新途径。

Dreded sediment which is composed of upland soil enriched with nutritive organic matters could be used beneficially as soil amendments or manufactured soil for horticultural use rather than discarded as spoil material. Dredged sediment used as soil amendments could improve the physical and chemical properties and fertility of soil,and so to promote plant growth. Also,dredged sediment could be used as manufactured soil for horticultural application with advantages of easy quality control and soil conservation, which is a new way of horticultural application.
