祁连山东端野生匍匐茎繁殖植物资源调查及园林绿化应用

Investigation of Wild Stolon Reproductive Plant Resources in the Eastern End of Qilian Mountains and Its Application in Landscaping

为了提高高原城市园林绿化效果,克服普通草坪草种早熟禾、高羊茅和三叶草等无法安全越冬的不足,调查了祁连山东端北麓地区野生匍匐茎繁殖植物资源,以此构建高原城市草毯替代普通草坪。调查发现,祁连山东端北麓地区有黄戴戴、野草莓、东方草莓、鹅绒委陵菜和等齿委陵菜5种匍匐茎繁殖植物,引种繁育和园林绿化应用后,表现出抗寒性强、生长量大、能安全越冬和短期形成一定盖度,在高原城市园林绿化中具有一定的应用前景。

In order to improve the effect of landscape greening in plateau cities and overcome the shortcomings of common lawn species such as Poa pratensis,Festuca arundinacea and Trifolium repens that cannot survive the winter safely,the wild stoloniferous plant resources in the northern foot of the eastern end of Qilian Mountains were investigated to construct a plateau urban grass blanket instead of common lawn.The survey found that there are six kinds of stoloniferous breeding plants in the northern foot of the eastern end of the Qilian Mountains,including Halerpestes ruthenica,Fragaria vesca,Fragaria orientalis,Potentilla anserina and Potentilla simulatrix.After introduction,breeding and landscaping application,they showed strong cold resistance,large growth,safe overwintering and short-term formation of a certain coverage,and had certain application prospects in the landscaping of plateau cities.
