摘要
对兰州市引种的27种观赏草的物候期、外部性状、观赏性和适应性进行2年的跟踪观测,评价并分析其在兰州地区的适应性和应用价值,分成A～D共4个等级。结果表明,蓝羊茅、玉带草、重金属柳枝稷、大油芒、斑叶芒、画眉草、紫穗狼尾草、披针叶苔草、细茎针茅、涝峪苔草、卡尔拂子茅、紫芒的气候适应性和观赏性表现较好,属于A等级,可无防护露地越冬,适用于兰州地区;青绿苔草、东方狼尾草、小兔子狼尾草和晨光芒表现较差,属于D等级,较不适应兰州气候。
The experiment was conducted to evaluate the adaptability and utilization value of 27 ornamental grasses in Lanzhou,the phenophase,basic morphological features,ornamental value and adaptability were observed for two years,and the ornamental grasses were divided to 4 grades（from A to D）.The results showed that the grasses in A group were suitable to be utilized in Lanzhou,performing satisfactory ornamental value and adaptability,could live through the winter without protection,including Festuca glauca＇Boulder blue＇,Phalaris arundinacea var.picta Linn.,Panicum virgatum,Spodiopogon sibiricus Trin.,Miscanthus sinensis＇Strictus＇,Eragrostis pilosa（Linn.）Beauv.,Pennisetum alopecuroides＇Purple＇,Carex lanceolata Boott,Stipa tenuissima,Carex giraldiana,Calamagrostis acutiflora＇Karl Foerster＇,Miscanthus sinensis Anderss＇purpurascens＇.The grasses in D group were not suitable in Lanzhou,including Carex breviculmis R.Br.,Pennisetum orientale,Pennisetum alopecuroides cv.＇Little Bunny＇,Miscanthus sinensis Anderss.＇Morning Light＇.
