摘　　要：为了减少花卉栽培中对草炭等不可再生资源的依赖,试验以秸秆、菇渣、锯末3种农业有机废弃物作为盆栽基质的主要成分,进行观赏桃栽培代用基质研究。结果表明:处理3(秸秆∶菇渣∶河沙=6∶2∶2)、处理6(秸秆∶菇渣∶锯末∶蛭石∶河沙=5∶3∶1∶1∶1)、处理7(秸秆∶菇渣∶锯末∶蛭石=3∶4∶1∶3)这3个基质配方的理化性质各项指标能满足观赏桃无土栽培基质的需求,结合生产成本考虑,处理3满足经济性和实用性,用其栽培的观赏桃生长健壮,枝叶繁茂,生长发育综合评价指数显著高于对照,基质结构稳定,可作为观赏桃无土栽培的代用基质。In order to reduce the reliance of flower culture on non-renewable resources （such as peat）, three kinds of agricultural organic castoffs （straw, mushroom residue and sawdust） were taken as the main components of substrate to study the substitute substrate for soilless culture of potted ornamental peach. The results showed that each index of physicochemical properties of treatment 3 （straw： mushroom residue： riversand=6：2：2）, treatment 6 （straw： mushroom residue： sawdust： vermiculite： riversand=5：3：1：1：1） and treatment 7 （straw： mushroom residue： sawdust： vermiculite=3：4：1：3） all can satisfy the requirements of substrate for soilless culture of omamental peach, but combined consideration of producing cost, only treatment 3 can satisfy the economic and practical requirements. The ornamental peach, which cultured with treatment 3, grew strong with luxuriance branches and leaves, and its comprehensive evaluation index of growth was obviously higher than control＇s. The structure of substrate in treatment 3 is stable, which can be used as substitute substrate for soilless culture of ornamental peach.
