林下耐荫观赏植物观赏性状评价

Evaluation of Ornamental Value of Shade-Tolerant Plants in Forest Canopy Closure

摘要: 应用层次分析法，对种植在不同郁闭度林下的观赏植物射干、木香薷、万寿菊、天人菊、紫苏、紫松果菊、藿香、紫玉簪和茖葱的株形、叶、花、生长能力、抗逆性及附加值等进行观赏性状的综合评价。结果表明，在低郁闭度林下观赏效果好的种类有万寿菊、紫松果菊、射干、木香薷和紫苏；在中郁闭度林下观赏效果较好的种类有紫松果菊、万寿菊、天人菊、木香薷和射干。在高郁闭度林下9种植物都不适合种植。

Abstract: The comprehensive evaluation of ornamental characteristics of nine ornamental plants, Belam-canda chinensis, Elsholtzia stauntoni, Tagetes erecta, Gaillardia pulchella, Perilla frutescens, Echinacea purpurea, Agastache rugosa, Hostaalbo-marginata and Allium victorialis, under different canopy densities was conducted by using the analytic hierarchy process (AHP), including plant shape, leaf, flower, growth ability, resistance and added value. The results showed as follows: Tagetes erecta, Echinacea purpurea, Belamcanda chinensis, Elsholtzia stauntoni and Perilla frutescens have the highest ornamental value planted in low forest canopy density; and Echinacea purpurea, Tagetes erecta, Gaillardia pulchella, Elsholtzia stauntoni and Belamcanda chinensis have higher ornamental value planted in medium forest canopy closure; all of the plants are not suitable for planting in high canopy closed forest.
