| 摘 要： | 以植株长势、观赏性、花序美感、叶片颜色及越冬成活率等为评价指标,利用灰色关联分析,对20个耐旱多年生观赏草品种越冬能力和春季景观效果进行了综合评价,结果表明:Elytrigia repens,Festuca ovina,Stipa krylovii,Ar-rhenatherum elatius,Eragrostis curvula5种观赏草与理想品种的关联度较高,具有很好的景观效果,可直接应用于园林美化,且各有优势;Anemathele lessoniana和Imperata cylindrical春季观赏价值较低,与理想品种的关联度分别为0.443 5与0.553 5;Arundo donax虽具一定的观赏性,但越冬成活率低。

| Abstract: | Ornamental characters of 20 introduced Drought-tolerent perennial Ornamental Grasses were evaluated using gray-correlation analysis based on the plant growing situation,ornamental character,inflorescence aesthetic feeling,leaf color and overwintering survive rate.The results showed that Elytrigia repens,Festuca ovina,Stipa krylovii,Arrhenatherum elatius and Eragrostis curvula have better ornamental effects and can be used for landscaping directly.The correlation degree of Anemathele lessoniana and Imperata cylindrical with ideal species are very low,only 0.4435 and 0.5535,respectively.The ornamental value of rundo donax is highter,but its overwrintering survival rate is very poor. |
