以杉木3代种子园和1.5代种子园良种营建对比试验林，对试验林11、21、34、45个月生的生长量进行调查分析，结果表明：杉木3代种子园良种生长显著优于1.5代种子园良种。其林分45个月生时，平均树高、胸径、单株立木材积分别为4.26m、5.97㎝、0.0083m3，分别比对照大53.24%、88.92%、336.84%，且林分整齐性优于杉木1.5代种子园良种。
以杉木3代種子園和1.5代種子園良種營建對比試驗林，對試驗林11、21、34、45箇月生的生長量進行調查分析，結果錶明：杉木3代種子園良種生長顯著優于1.5代種子園良種。其林分45箇月生時，平均樹高、胸徑、單株立木材積分彆為4.26m、5.97㎝、0.0083m3，分彆比對照大53.24%、88.92%、336.84%，且林分整齊性優于杉木1.5代種子園良種。

The stand was established with the 3rd and 1.5th generation seed orchard varieties of Cunning-hamia Lanceolata on national forest farm of Huaqiao in 2010. Growth of stand was examined at the age of 11,21,34 and 45 months. The result showed that the 3rd generation variety grown significantly well than the 1.5th generation variety. The average tree height,diameter at breast height and volume of the 3rd gen-eration variety was 4.26m,5.97㎝ and 0.0083m3 respectively at the age of 45 months, which was respec-tively more 53.24%、88.92%、336.84% than that of the 1.5th generation variety.
