截叶毛白杨是毛白杨的一个变种,树干通直高大,枝叶茂密,比较耐旱、耐水湿、耐碱土。据调查:在同样立地条件下,截叶毛白杨比毛白杨生长快30%左右。由于适应性强,生长迅速,很受群众欢迎。截叶毛白杨可以用扦插、留根、埋条、埋株、嫁接等多种方法繁殖。目前生产上常用扦插育苗,其它方法因成本高,产量少,质量差,一般多不采用。截叶毛白杨与毛白杨相比,扦插育苗生根困难,成活率低。据在省林科所渭河试验站试验,1975年的成活率仅20%,1977年
Populus trichocarpa is a variant of Populus trichocarpa, trunk straight tall, dense foliage, more drought-resistant, water-wet, alkali-resistant soil. According to the survey: in the same site conditions, cut leaf Populus faster than Populus growth of about 30%. Due to adaptability, rapid growth, very popular with the masses. Populus trichocarpa cuttings can be cuttings, root, buried, buried, grafting and other methods of breeding. At present, cutting seedlings commonly used in production, other methods due to high cost, less output, poor quality, generally do not use more. Compared with Populus tomentosa cuttings, Cuttage seedling rooting difficulties, low survival rate. According to the Weihe River Experimental Station in Linke County, the survival rate in 1975 was only 20% in 1977
