摘要
[目的]本文旨在构建出适宜的综合评价体系以便筛选出优良的多头切花菊立面装饰品种。[方法]从300个切花品种中初选出82个多头切花菊品种,对其8个与立面装饰相关的性状进行观测记录,借助层次分析法、灰色关联度分析法和K-means聚类分析法建立评价体系,并基于该体系开展品种评价。[结果]采用层次分析法确定各评价指标的权重值,其中插满单个标准花泥所需花枝数的权重值最大,为0.291;其次是10 cm花枝的花朵数和观赏寿命,权重值分别为0.160、0.156。在此基础上将82个品种进行灰色关联度分析,通过K-means聚类分析法分为4个等级,其中优秀品种9个,良好品种16个,一般品种27个,较差品种30个,分别占11.0%、19.5%、32.9%、36.6%。[结论]通过层次分析法和灰色关联度分析法建立的评价体系,可以筛选出适宜立面装饰的多头切花菊品种。
[Objectives]The objective of this study was to establish an evaluation system for selecting excellent spray cut chrysanthemum varieties for facade decoration.[Methods]The analytic hierarchy process,grey correlation analysis and K-means cluster analysis were used to construct the facade decoration evaluation system for 82 spray cut chrysanthemum varieties which were selected from 300 cut chrysanthemum varieties.[Results]The maximum weighted value was observed in the number of flower branches which could fully cover a single standard flower mud surface,showed 0.291,followed by the weighted value of the number of 10 cm length of flower branches,showed 0.160,and then the ornamental life found as 0.156.Based on the above results,82 varieties were further divided into four groups by gray correlation analysis and K-means cluster analysis,and the results indicated that 9 varieties belonged to the excellent rank(11.0%),16 varieties were included in the good rank(19.5%),27 varieties in general varieties(32.9%)and 30 varieties in poor rank(36.6%).[Conclusions]The evaluation system based on the gray correlation analysis and grey correlation analysis are reliable and suitable for spray cut chrysanthemum varieties selecting for the facade decoration.
