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。
The cuttings afforestation of one-year-old seedlings rooted at 1 to 5 years of the clones of Xianglin-90 clones was conducted to study the effect of rooting pile age on the afforestation effect of poplar. The results showed that DBH, seedling height and volume of the rootstock during the afforestation were all significantly different among the sprouts and shoots of the root piles of different ages. The DBH, height and volume at the first year and the fourth year after afforestation were significantly different Despite differences in afforestation of seedlings, but the difference was not significant. The results showed that 1-year rooting of 1 to 5 years root sprout 1-year-old seedlings are suitable for cutting and afforestation.
