摘　　要：为了丰富北京地区彩叶树品种,扩大‘红霞杨’的种植范围,将‘红霞杨’从四川成都引种到北京房山,进行了物候期观察、叶色变化观察、扦插繁殖、嫁接繁殖、土壤及光强适应性试验。结果表明:‘红霞杨’在北京房山能完成一个完整的生命活动周期;扦插繁殖成活率在80%以上;嫁接繁殖成活率在85%以上;在垃圾土、牧场土及建筑土中能生长,但长势不良,在苗圃土中生长良好;彩色叶片对光强的应激反应比较敏感,强光下叶色鲜艳,但有焦叶现象,弱光下叶色会返绿,且生长较弱,在75%的轻度遮阴下生长良好,既不焦叶,也能呈现橘红、金黄、黄绿一树三色的彩色效果,绿化时可以选择栽植在有适度遮阴的地块,会出现与众不同的彩色景观。The paper aims to enrich the variety of colored-leaf trees in Beijing and expand the planting area of Populus euramericana cv.‘Hongxia＇.The Populus euramericana cv.‘Hongxia＇was introduced to Fangshan,Beijing from Chengdu, Sichuan, the phenological period observation, color change observation, cuttingpropagation, grafting propagation and the adaptability analysis of the plant to soil and light intensity werecarried out. The results showed that： Populus euramericana cv.‘Hongxia＇could complete the life cycle inFangshan, Beijing; the survival rate of cutting propagation was over 80%, and the survival rate of graftingpropagation was over 85%; it could grow in the refuse soil, the pasture soil and the architecture soil, but it grewin an undesirable way; it grew well in the nursery soil; the leaves were sensible to the stress reaction of the lightintensity, and the colors of the leaves were bright; and there was the phenomenon of leaf scald, the leaf colormay become green again and the leaves grew weakly; but the leaves grew well in the 75% of shading, and therewas no phenomenon of leaf scald. The leaves of the tree could have the colorful effect of three colors： redorange, golden yellow and yellow green. In landscaping, Populus euramericana cv.‘Hongxia＇can be planted inthe plot of proper shading to achieve unusual colorful landscape.
