摘　　要：[目的]探究百脉根等8种宿根地被的低温适应能力,为引种工作及园林应用提供理论参考依据。[方法]以百脉根等8种宿根地被为研究试材,采用自然低温处理结合形态观察的方法,对其抗低温能力进行研究。[结果]通过对供试植株连续2年露地越冬情况的观测,百脉根、紫花地丁、地被菊、百里香露地越冬存活率均高达90%以上,越冬表现良好、观赏性状优良。[结论]百脉根、地被菊、百里香、紫花地丁等地被材料,适合在本地区大面积应用,园林应用前景广阔。其中,紫花地丁萌芽早、花期早、花色鲜艳、抗寒性强,可以填补早春观花地被的空白。[ Objective ] To explore the low temperature adaptability of eight perennials, so as to provide theoretical basis for their introduction to landscaping. [ Method ] Lotus corniculatus and other seven perennial materials were collected as samples to study their cold resistance by natural low temperature treatment and morphological observation. [ Result ] After the two-year observation of wintering of the tested plants, Lo- tus corniculatus, ground cover Chrysanthemum, Thymus mongolicus and Viola philippica had broad application prospects in the garden with bet- ter ornamental characters and overwinter performance, their wintering survival rates were all above 90%. [ Conclusion ] Lotus corniculatus, ~round cover Chrysanthemum, Thymus mongolicus and Viola philippica were suitable to be popularized in large areas, among which Viola phil- ippica can fill the blank of flowering plants in early spring with the characteristics of earlier germination, earlier flowering, bright color and strong cold stress tolerance.
