摘要
在响叶杨次生林中，当树龄达到１５ａ以上时，可采用优势木对比法和绝对值生长量法选择优树。其无性繁殖，可采用埋根促萌、嫁接复壮、组织培养等方法幼化处理后的嫩枝扦插，生根率达８０％。
In secondary forests of Chinese aspes with the age of more than 15 years,the dominant tree comparative method and absolute growth method can be used in the selection of select trees The vegetative propagation methods,including germination by embedding roots, rejuvenation by grafting and tissue cultures,etc.,can raise the rootability up to 80 percent
