几种地被植物抗逆性比较

COMPARISON OF STRESS RESISTANCE IN SEVERAL GROUND COVERING PLANTS

有关野生地被植物在城市绿化中应用方面的研究愈来愈受到重视。目前对野生地被植物研究已取得了很多成果,并得到推广。本文就部分北京地区野生地被植物的耐旱耐热性进行了初步分析,结果表明植物的抗旱性从强到弱依次为:甘野菊、青杞、旋覆花、连钱草、大叶铁线莲、委陵菜、蛇莓、匍枝委陵菜。其抗热性从强到弱依次为:委陵菜≈匍枝委陵菜、旋覆花、甘野菊、连钱草、玉竹、蛇莓、青杞、大叶铁线莲、匍枝毛茛。以上研究结果为其在北京地区乃至其他地区的推广应用提供了理论基础,同时为地被植物的相关研究提供了可借鉴的方法。

It is paid more and more attention to wild ground covering plants in urban greening applied research.Achievements have been registered and gotten promotion in present studies of wild ground covering plants.This article analyzed drought and heat resistance characters of part of the wild ground covering plants around Beijing area.The results showed that the drought resistance of those plants from strong to weak was as follows： D.Chrysanthemum,Solanum seaforthianum,Inula japonica,Glechoma hederacea L.,Clematis heracleifolia,Potentilla flagellaris,Duchesnea indica,Potentilla stolonifer.The heat resistance from strong to weak as follows was： Potentilla chinensis Ser.and Potentilla flagellaris,Inula japonica,D.lavandulifolium,Glechoma hederacea L.,Polygonatum doratum,Duchesnea indica,Solanum septemlobum Bge.,Clematis heracleifolia,Potentilla eptans L.The results above provides a theoretical basis for the promotion and application of the wild ground covering plants in other areas around the Beijing,simultaneously,they also provide useful methods for the research of ground cover plants.
