| 摘 要： | 通过对高脂马尾松扦插苗、实生苗进行造林试验，结果表明：造林后2～5年，两种林分平均保存率均达到95％以上；3、4年生时树高、胸径、单株材积差异极显著，4年生时扦插苗的幼林树高、胸径、冠幅、单株材积平均分别高于同龄实生苗的13．11％、24．95％、18．53％和69．81％，说明利用优良无性系繁殖扦插苗进行造林是可行的。

| Abstract: | Afforestation experiment about cutting seedling and seedling of high-resin-yield Masson pine were made in the article. The results showed that the survival rate of the two seedling had kept high level in the first five years. Interestingly, the growth indexes of the cutting seedling include height, diameter, crown width, individual volume were higher than those of the seedlings at the fourth year. So, a simple conclusion can be made that using cutting seedling origin from superior clone for forestation was feasible. |
