6种观赏草在太原地区的引种试验

Introduction tests of six species of ornamental grasses in Taiyuan area

观赏草具有观赏价值高、抗逆性强和养护成本低等特性,近年在城市绿化造景使用普遍。依据太原地区自然条件、气候特征和城市绿化现状,引进6种景观草进行栽培试验,以成活率、物候期、越冬性、越夏性为观测指标,研究6种观赏草在太原地区适应性表现。试验结果表明:东方狼尾草、细茎针茅、蓝羊茅、小兔子狼尾草、重金属柳枝稷5种能适应太原地区的气候条件,适合太原地区引种栽植,紫叶狼尾草在太原地区不能露地越冬,不适合太原地区引种栽植。

Having the characteristics of high ornamental value,strong resistance to adversity,good adaptability and low maintenance cost,ornamental grasses have been widely used in urban greening in recent years.According to the natural conditions,climate environment and urban greening situation in Taiyuan,six species of landscape grasses were introduced for cultivation experiments,and the survival rate,phenological period,overwintering and summering properties were used as observation indicators to study the adaptability of the six ornamental grasses.The results show:Pennisetumorientale(L.)Spreng,StipatenuissimaVill,FestucaglaucaVill,Pennisetumalopecuroides cv.’Little Bunny’ and Panicumvirgatum can adapt to the climatic condition in Taiyuan area,and are suitable for introduction and planting in the area.Pennisetumalopecuroides(L.)Spreng,which can not live through the open fields,is not suitable for introduction and planting in Taiyuan area.The study provides a basis for the garden application of ornamental grasses in Taiyuan area.
