Mixed peat is commonly used as the substrate of cucumber (Cucumis sativus L.). But the global resource of peat declines year by year and the ore-source wetland suffers serious damage. Coir fiber dust is an abundant, cheap, environmentally friendly agricultural waste with physical and chemical properties similar with peat, which makes it a potential alternative to peat. However, treatment of coir fiber dust is required before being used as substrate. To effectively utilize coconut shell waste, this research aimed the treatment method of coir dust as the substrates to produce cucumber in the greenhouse.調配椰纖屑養液栽培氮鉀胡瓜treated coir fiber dustnutrient culturenitrogenpotassiumcucumber
