摘 要：
以泥炭土、黄心土、细砂和珍珠岩为基质成分,设计了14种不同的配方,应用灰色关联分析方法探讨不同基质配方与福建紫薇扦插生根效果的关系。结果表明,不同基质配方的生根效果有显著的差异,以泥炭土(33.3%)+黄心土(33.3%)+细砂(33.3%)生根效果最好,生根率达89.3%。灰色关联分析表明,泥炭土有利于提高福建紫薇扦插生根率,细砂有利于增加扦插生根条数,黄心土有利于提高扦插生根长度。

摘 要：
Four kinds of major mediums including turf soil,yellow soil,sand and perlite were selected to 14 kinds of various mixture medium prescriptions.The relationships between the various medium prescriptions and Lagerstroemia limii Merr.cutting and rooting effects were discussed by the grey relational analysis method.The result showed that the different medium prescription rooting effects were different significantly,the optimum mixture was 33.3% of turf soil+33.3% of yellow soil +33.3% of fine sand,with the mixture,the cutting rooting rate reached 89.3%.By the grey relativity analysis,the results showed that turf soil was good for increasing the cutting rooting rate,fine sand was good for increasing number of roots,and yellow soil was good for increasing length of roots.
