采用湘林-90无性系杨1～5年生根桩萌条的1年生苗扦插造林，研究萌条的根桩年龄对杨树扦插造林效果的影响。结果表明：造林时的胸径、苗高、材积在不同年龄根桩的萌条苗间均有显著差异，造林后的第1年、第4年，胸径、树高、材积在不同年龄根桩萌条苗的造林地间虽有差异，但差异均不显著。试验结果表明1～5年生根桩萌条的1年生苗都适宜扦插造林。

Using the XL-90 clone of poplar with the germination braches of stump roots in one to five years old for affor-estation,the effect of different age of stump root on the growth of cuttage afforestation of poplar was studied. The results showed that,there were significant differences in DBH,height and volume among different age of stump root of germina-tion braches in afforestation. Although there were differences in DBH,height and volume in the first year and fourth year after afforestation,but there were no significant differences. It indicated that the one-year-old seedling with stump root of one to five years old were suitable for cuttage afforestation.
