采用4 a生钟萼木Bretschneidera sinensis实生苗进行不同海拔造林对比试验，对造林后4 a的净生长量进行全面调查。结果表明，不同海拔对造林成活率的影响不显著，高生长、地径生长差异显著。在海拔350、660、750 m处树高平均净生长量分别为72、164、162 cm，地径平均净生长量分别为0.93、1.53、1.83 cm，说明在较高海拔造林的树高、地径生长量均高于低海拔，造林地对海拔要求相对较高。

Afforestation trial on 4-year-old Bretschneidera sinensis were conduted at different altitudes in Jianning county, Fujian province. And the net growth of tree height and diameter on root collar (DRC) were investigated after 4 to 8 years planting. The results showed that there were insignificant differences in afforestation survival rate among the B. sinensis seedlings planted at different altitudes. But the increment of tree height and DRC among those at different altitudes differed significantly. The increments of tree height at altitudes 350, 660, 750 m were 72, 164, 162 cm, respectively. Meanwhile, the growth mass of DRC at altitudes 350, 660, 750 m were 0.93, 1.53, 1.83 cm respectively. In a word, the net growth of tree height and DRC were increased with a rise in altitude for afforestation ranging from 350-750 m. Consequently altitude was one of the most important factors for B. sinensis seedlings afforestation.
