摘要
进行沿海较高海拔山地引种秃杉适应性试验,结果表明:秃杉适应性强,造林成活率、保存率高,其与柳杉一样可适应贫瘠较高海拔山地的气候环境。秃杉前2年生长较慢,随后生长速度较快并逐渐超过柳杉、马尾松;九年生林分平均树高、胸径、单株材积和林分蓄积分别达9.0 m、8.7 cm、0.028 4 m3和45.42 m3/hm2,分别比同林龄柳杉提高了8.40%、7.40%、26.34%和23.48%。此外,秃杉的耐寒性、抗风性以及抗病虫害能力强,可以作为沿海较高海拔山区代替马尾松、杉木以及柳杉的栽培和迹地更新树种。
Introduction adaptability of Taiwaniaflousiana in coastal higher altitude mountain was studied,the resuhs showed that the Taiwania flousiana adaptability was strong,survival rate and preservation rate was high.It was the same with Ctyptomeria which could be adapted to the barren higher altitude mountain climate and environment.Growth speed in the first two years was slow, followed by a faster growth rate and gradually more than Cryptomeria and Pinus massoniana. Average tree height, diameter at breast height,individual volume and accumulation of 9a tree was 9.0 m, 8.7 cm, 0.028 4 m3 and 45.42 m3/hm2,respectiveiy.Compared with the same age Cryptomeria,the indexes improved 8.40% ,7.400/0,26.34% and 23.48%, respectively.In addition, its ability of the cold resistance ,wind resistance and pest-resistant were stronger ,it could be used as coastal higher altitude mountain instead of Pinus massoniana, fir and Cryptomeria trees cultivation and slash update.
