摘　　要：为减少花卉无土栽培对泥炭资源的依赖,该试验以玉米秆、麦秆、锯末和菇渣4种有机废弃物作为基质的主要成分,探讨取代泥炭作为一品红栽培基质的可行性。结果表明,V(玉米秆粉)∶V(珍珠岩)为3∶1、V(菇渣)∶V(珍珠岩)为3∶1、V(菇渣)∶V(蛭石)为3∶1,这3个处理的理化性质的各项指标均在无土栽培基质的理想范围内,用其栽培的一品红根系生长健壮,生长发育综合表现显著优于对照,可作为一品红无土栽培的代用基质。In order to reduce the dependence on peat as primary growing medium of Euphorbia pulcherrima, the feasibility of experimenting four kinds of organic castoffs, including corn stalk, wheat-straw, sawdust, and spent mushroom compost, was investigated. The results indicated that the physical and chemical characteristics of the three treatments, ie V（corn stalk）： V（perlite） 3：1, V（spent mushroom compost） ： Y（perlite） 3：1 and V （spent mushroom compost） ： V （vermiculite） 3： 1, satisfied the general requirements of growing media. Not only the roots of E. pulcherrima in those treatments were robust, the comprehensive performance of growth and development was also significantly better than that in control. Thus, the treatments can be good substitutes as soilless growing media of E. pulcherrima.
