优良草本花卉的引种评价与应用

本研究对引进的 30 种草本花卉在郴州地区进行了引种栽培试验，观测并记录了其生物学特性、观赏性状、生态适应性等，并在此基础上运用层次分析法建立了一套适合草本花卉的综合评价模型，以草花的观赏性、适应性、生长性作为优良草花品种选择的主要依据，确定了花色、花姿、花期长度、花覆盖度、抗逆性、抗病虫性、管理难易、繁殖能力等14个评价指标，对30种花卉进行了综合评价。筛选出香彩雀等Ⅰ级草花15种，雏菊等Ⅱ级草花13种，天竺葵等Ⅲ级花草花 2种，为草本花卉在城区园林绿化中大规模的推广应用提供参考。

Introduction and Application of Good Herbal Flowers

30 species of herbaceous flowers are introduced and cultivated in Chenzhou, and their biological characteristics, ornamental characters and ecological adaptability are observed and recorded, and a comprehensive evaluation model of herbaceous flowers is established by Analytic Hierarchy Process (AHP). According to the ornamental, adaptive and growing properties of herbaceous flowers, 14 evaluation indexes such as the flower color, flower posture, flowering period length, flower coverage, resistance, pest resistance, management difficulty, and reproductive ability of the 30 species are determined, to screen out 15 species of Grade Ⅰ, 13 species of Grade Ⅱ, and 2 species of Grade Ⅲ, providing a reference for the large- scale promotion and application of herbaceous flowers in urban landscape greening.
