大庆地区委陵菜属植物园林应用评价

分析了大庆地区的自然状况以及委陵菜属植物资源在大庆地区的分布状况,汇总了9种委陵菜属植物种类,结合实地踏查、小区试验,以及生物特征观测等方法,筛选出适合园林绿化的7种委陵菜属植物,并从观赏性、抗旱性和抗寒性、耐践踏性、环境的适应性、覆盖度、养护频度等园林应用方面对其进行评价,认为其观赏效果颇佳;具有一定的抗旱性和抗寒性;耐践踏能力强,且光叉叶委陵菜、蔓委陵菜强于伏委陵菜、鹅绒委陵菜,委陵菜、翻白委陵菜、蒿叶委陵菜次之;委陵菜的植物形态、结构与其所处的环境是协调统一的;鹅绒委陵菜、蔓委陵菜、光叉叶委陵菜的覆盖度优于伏委陵菜、蒿叶委陵菜、翻白委陵菜;委陵菜植物无需人工料理和养护,是理想的园林绿化植物。在此基础上,就委陵菜属植物在大庆城市绿化中的保护和开发利用提出了建议。

Evaluation on Landscape Application of Plants of Potentilla in Daqing City

The paper had analyzed natural condition of Daqing Area and distribution of plants of Potentilla in Daqing,and summarized 9 varieties of Potentilla.Based on field study and plot experiment and through observation of biological traits,7 varieties of Potentilla had been identified suitable for landscaping;and evaluation had been conducted on their landscape application from the perspective of ornament,drought resistance,cold resistance,trampling resistance,adaptability to environment,coverage,and maintenance frequency.It was considered that the ornamental effect was quite good.They had certain drought resistance and cold resistance,and strong trampling resistance.That of Potentilla bifurca L.var.glabrata Lehm.and Potentilla flagellaris Willd ex Schlecht.was stronger than that of Potentilla paradoxa Nutt.and Potentilla anserina L.,and then Potentilla chinensis Ser.,Potentilla discolor Bunge.and Potentilla tanacetifolia Willd ex Schlecht.were secondary.The pattern and structure of plants of Potentilla were coordinated and unified with the environment.The coverage of P.anserina L.,P.flagellaris Willd ex Schlecht.,and P.bifurca L.var.glabrata Lehm.was higher than that of P.paradoxa Nutt.and P.Tanacetifolia Willd ex Schlecht.and P.discolor Bunge..Plants of Potentilla didn't need to be maintained by men and they were ideal landscaping plants.On this basis,it had proposed suggestions on protection and development of landscaping plants of Potentilla in Daqing City.
