摘要
为了筛选出抗寒、耐旱的垂直绿化树种,在高寒冷凉区引种5种藤本植物五叶地锦、山荞麦、啤酒花、美国凌霄和贝达葡萄。结果表明:山荞麦和贝达葡萄栽植成活率高、生长量大、越冬性好,保存率高、景观效果优,两者的栽植成活率、覆盖度、越冬后枝条和根系死亡率、单株萌芽数、保存率分别为96.43%、82.55%、2.52%、1.06%、21.37个/株和93.94%;94.33%、72.89%、6.39%、2.18%、16.57个/株和92.82%,且景观效果表现为枝叶浓密、分布均匀,综合评价为优,此两树种在高寒冷凉区垂直绿化中具有一定应用和推广价值。
In order to screen cold and drought resistant tree species for vertical greening,five lianas Parthenocissus quinquefolia,Polygonum aubertii,Humulus lupulus,Campsis radicans and Vitisriparia×V.labrusca were introduced to high cold area.The result showed that the survival rate,growth,wintering ability,preservation rate,landscape effects of Polygonum aubertii and Vitisriparia×V.labrusca were higher in all tree species,the survival rate,coverage,branch and root mortality after wintering,single plant sprout number,preservation rate were 96.43%,82.55%,2.52%,1.06%,21.37/plant and 93.94%;94.33%,72.89%,6.39%,2.18%,16.57/plant and 92.82% separately,and landscape effects showed that the branches and leaves were thick and distributed evenly,the comprehensive evaluation was fine,the two tree species above have certain application and promotion value of vertical greening in high cold area.
