- 摘要:
- 以垂盆草(Sedum sarmentosum)、凹叶景天(Sedum emarginatum)、高景天(Sedum kamtschaticumvar.ellacombeanum)等3种景天科植物为供试植物,以堆肥、煤渣、陶粒、河沙等为原料,进行了不同配比的轻型屋顶绿化栽培基质配方试验;并采用聚类分析及投影寻踪综合评价方法,对栽培基质配方理化特性及栽培效果进行了比较,以期筛选出不同植物适宜的栽培基质配方。结果表明:采用投影寻踪综合评价方法可对植物多指标参数进行有效降维处理,是栽培基质筛选研究的良好方法;筛选出的栽培基质配方适宜我国轻型屋顶绿化系统特征,具有较好的推广前景。
- 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.
