摘要
为了给屋顶绿化基质提供轻型、价廉的新型材料,促进废弃物的再利用,应用正交试验设计方法,将粉煤灰、煤渣、秸秆与园林废弃物作为基质组成的4成分,选用L9(34)正交表安排各因素的配比。结果表明:9种基质,测定各基质的物理化学特性,并分别在各基质中扦插景天属植物,观测分析插条的成活率、生根率与平均生根数等相关指标结果表明:最优化的基质配比类型有3种,粉煤灰、煤渣、秸秆与园林废弃物的体积配比分别为1∶1∶1∶1、1∶2∶2∶2与2∶1∶2∶1。
In order to provide light-duty, cheaper growing medium for roof greening and recycle waste, orthogonal design methods were used. The non-treated fly ash, crushed slag, straw and waste of garden plants were used as four factors of growing medium composes. According to the L9(3^4)orthogonal tab, nine types of medium were obtained. The physicschemical characters of growing medium were measured. Moreover, cutting propagation of sedums was conducted in the growing medium. The survival rate, root rate and average quantity of roots were observed. Three most optimized growing medium types were selected. The volume ratio of fly ash, slag, straw and waste of garden plants were 1 : 1 : 1 : 1, 1:2:2:2and2: 1:2:1.
