基于AHP的73种石斛兰观赏性及栽培适应性的研究

A Study on Ornamental and Cultivated Adaptability of 73 Species of Dendrobium Officinale Based on AHP

利用层次分析法对引种的73种(品种)石斛兰花的颜色、花直径、花朵张开程度、芳香性、花期长短、一支花序花朵数、花序排列情况、植株高度、植株形态及叶片观赏性、生态习性、繁殖难易度、生长状况等指标进行系统分析和评价其观赏特性、栽培适应性和经济价值,根据综合评价值构造4层模型和评价标准,将73种(品种)石斛兰在南宁地区的适应情况和观赏价值分为4个等级。结果表明:兜唇石斛、黄喉石斛等24种综合评分结果≥3.5151,根据等级评价模型,可直接运用于园林景观或盆栽花卉等。因此,兜唇石斛、黄喉石斛等24种石斛适合南宁地区栽培且观赏性较好,可直接运用在广西南宁城市景观的造景中。

The following indicators of the color,flower diameter,flower opening degree,aromaticity,flowering length,flower number,inflorescence arrangement,plant height,plant morphology and leaf ornamental,ecological habit,reproduction difficulty and growth status of 73 species of dendrobium officinale were systematically analyzed and evaluated by applying analytic hierarchy process.According to the comprehensive evaluation value,the four-layer model and evaluation standard were constructed,and the adaptation and ornamental value of 73 species of dendrobium officinale in Nanning area were divided into four grades.According to the grade evaluation model,the results≥3.5151,which can be directly used in landscape or potted flowers,so 24 species of dendrobium candidum and dendrobium officinale are suitable for cultivation and appreciation in Nanning area,and can be directly used in the landscape of Nanning City in Guangxi.
