对甘肃金昌地区引进的20 个观赏草品种进行观赏性和适应性评价，结果表明：绒毛狼尾草（Pennisetum villosum）、‘ 紫光’ 狼尾草（P. alopecuroides ‘Ziguang’）、玉带草（Phalaris arundinacea）和柳枝稷（Panicum virgatum）分蘖时间较早，7 月初开始分蘖；20 种观赏草的成活率、生长状况和观赏价值都较好；除粉黛乱子草（Muhlenbergia capillaris）、‘ 紫叶’ 稻（Oryza sativa ‘Black Madras’）、绒毛狼尾草和‘ 紫
叶’ 狼尾草（P. setaceum ‘Rubrum’）外其它14 种观赏草均以休眠形式能自然越冬；‘ 纤细’ 芒（Miscanthus sinensis ‘Xianxi’）、‘ 细叶’ 芒（M. sinensis ‘Gracillimus’）、‘ 花叶’ 芒（M. sinensis ‘Variegatus’）和‘ 斑叶’芒（M. sinensis ‘Zebrinus’）的观赏性更好且适应性更强，与理想种的关联度更高，在金昌地区可直接作为园林绿化植物进行推广应用。

Abstract: |

The ornamental and adaptability of 20 ornamental grasses introduced in Jinchang of Gansu province were evaluated. The tiller time of Pennisetum villosum, P. alopecuroides ‘Ziguang’, Phalaris arundinacea and Panicum virgatum are earlier and the tiller begins in early July. The survival rate, growth status and ornamental value of 20 kinds of ornamental grasses are good. In addition to Muhlenbergia capillaris, Oryza sativa ‘Black Madras’, P. ennisetum villosum and P. setaceum ‘Rubrum’, the other 14 kinds of ornamental grass are in the form of hibernation can naturally winter. Miscanthus sinensis ‘Xianxi’, M. sinensis ‘Gracillimus’, M. sinensis ‘Variegatus’and M. sinensis ‘Zebrinus’ are more ornamental and adaptable, and the association with the ideal species is higher. The ornamental grasses can be directly used as a garden greening plants to promote the application in Jinchang.
