摘　　要：为了探索‘全红杨’关键栽培技术,采用遮荫法、融雪剂浇灌法、色素测定法、材质分析法、砧木筛选法及田间观察法等方法,对‘全红杨’进行多方面研究。结果表明,‘全红杨’净光合速率日变化为"双峰"曲线,不耐晒,但有一定的耐荫性,可以栽植在轻度遮荫的地方,长势正常,叶色不"返绿";‘全红杨’具有一定的耐融雪剂能力,可以作行道树;‘全红杨’材质指标值仅次于‘加杨’,可以发展用材林;‘全红杨’最佳嫁接砧木为‘北方青杨’,高接后,树干通直,树皮青绿,树冠紫红,能生产出更加优质的‘全红杨’彩色景观树。In order to explore key cultivation technology of Populus euramericana‘Quanhong’,a research onit was carried out with methods including shading,irrigation with snow-melting agent,pigment measurement,material analysis,stock selection and field observation.The results showed that there were two peaks on thecurve of diurnal variations of net photosynthetic rate of Populus euramericana‘Quanhong’; the tree could nottolerate high basking,but performed better in shade-tolerance.Hence,it grew well in slight shading area.Furthermore,Populus euramericana‘Quanhong’was resistant to snow-melting agent to a certain extent,andcould be used as border trees.In addition,index values of Populus euramericana‘Quanhong’were just secondto that of Populus × canadensis Moench,and therefore,Populus euramericana‘Quanhong’could be used fortimber forests.The optimal stock was Populus cathayana,for which the grafted trees grew straight and tall,whose bark was dark grey or greenish and crown was purplish red,thus could add more colors to the landscape.
