Abstract:
Taking three Crassulaceae plants Sedum sarmentosum,Sedum emarginatum,and Sedum kamtschaticum var.ellacombeanum as test materials,and taking sawdust compost,coal cinder，horticultural ceramisite and river sand as the component materials in the substrate formulation,the substrate formulation screening test of different ratios in lightweight roof greening was done.The substrate physical chemical properties and cultivation effect were evaluated by cluster analysis and projection pursuit method,in order to screen the optimum formulations.The results showed that efficiency of the projection pursuit method was demonstrated to substrate formulation screening by reducing the multiple parameters of plant growth,and the obtained substrate formulations were fit for the characters of lightweight roof greening system in China,promising with preferable promotion value.
