摘  要:
峦大杉经 12a的引种造林试验表明 :1年生苗平均高 2 0 5cm ,平均地径 0 37cm ;造林后第 12a林分平均树高 10 4~11 1m ,胸径 13 5~ 14 1cm ;造林初期生长缓慢 ,树高在第 2a后、胸径在第 4a后年生长量与本地杉木无显著差异 ;12年生的纯林与混交林树高、胸径值差异不显著 ;育苗与造林技术均容易掌握 ,具有重要的引种价值。

摘  要:
The 12 year Cunninghamia lanceolata Var. konishii introduction afforestation experiment shows that the 1 year old average seedling height reaches 20.5 cm,the average ground diameter is 0.37 cm;the average stand height in the 12 th year of afforestation reaches 10.4~11.1m,the dbh is 13.5~14.1 cm;the growth is slow at the early stage of afforestation,the annual growth increment of height 2 years later and dbh 4 years later has no evident difference with that of local Cunninghamia lanceolata;the height and dbh values of 12 year old pure forests have no obvious difference with those of mixed forests;the seedling culture and afforestation techniques are relatively grasped without difficulty and possesses important introduction value.
