Abstract：In order to provide high-quality,cheaper growing medium for the ecological management of waste land,and promote the reuse of waste,orthogonal design methods were used.The crushed slag,straw,and non-treated fly ash were used as three factors of growing medium composes.According to the L9(34) orthogonal tab,nine different ratios of growing medium were obtained.The physics-chemical character of growing mediums were measured,then the Festuca arundinacea seeds were planted in the growing medium.Emergence rate,survival rate,and biomass of Festuca arundinacea were observed and analysed.The most optimized growing medium type was A2B2C3,The volume ratio of fly ash,slag,and straw were 2 to 2 to 3.The order of the primary and secondary factors were B(slag),A(fly ash),and C(straw).
