| 摘 要： | 以生长状况、植株观赏价值、花序美感、株高等性状为评价指标, 利用灰色关联分析, 对20个多年生观赏草在北京地区春季、夏季和秋季的生长状况和观赏价值进行了综合评价。结果表明:Anemathele lessoniana和Imperata cylindrica不能适于北京地区生长; Elytrigia repens、Festuca ovina、Eragrostis curvula和Stipa krylovii在春季能产生优良的景观效果, 与理想种的关联度达0.80以上; Arundinella hirta、Elytrigia repens、Eragrostis curvula、Miscanthus sinensis‘Variegatus’及Pennisetum alopecuroides的夏季景观效果很好, 与理想种的关联度均在0.70 以上; 而Miscanthus sinensis ‘Variegatus’、Spodiopogon sibiricus、A rundinella hirta及Schizachyrium scoparium 在秋季植株色彩变化明显, 与理想种的关联度均达0.80以上。

| Abstract: | Growth and ornamental value of 20 introduced perennial ornamental grass were evaluated in Beijing by gray-correlation analysis based on the characters of p lant growth, ornamental value, inflorescence aesthetics, leaf color and over wintering survival etc. The results showed that Anemathele lessoniana and Imperata cylindrica were not suitable for growing in Beijing because of their low overwintering survivals. Elytrigia repens, Festuca ovina, Stipa krylovii and Eragrostis curvula can be used for landscape in spring and their correlation degrees to perfect species were more than 0.80 in spring. Arundinella hirta, Elytrigia repens, Eragrostis curvula, M iscanthus sinensis‘Variegatus’ and Pennisetum alopecuroides have good ornamental values in summer aswell as higher correlation degrees. The p lant color of Miscanthus sinensis‘Variegatus’, Spodiopogon sibiricus, Arundinella hirta and Schizachyrium scoparium changed alongwith the season alternation, and their correlation degrees were higher than 0.80. |
