The results of nursery experiments showed that the survival rate and growth rate of Populus × euramericana 107 in the western region of Wen’an County (soil type is sandy loamy soil) were higher than those of Zhonglin 46, Langfang Yang 2 and Holland 3930. In the eastern area of Wen’an County (soil type is clayey moist soil), the survival rate and growth rate of cuttings of Langfang Yang 2 were greater than that of Europe and the United States Yang 107, larger than Zhonglin 46 and the Netherlands 3930.
