| 摘 要： | 25个种源在3种不同立地造林的结果显示:立地对西南桦生长影响大,3种立地幼林胸径、树高、材积生长差异显著。在好立地上西南桦胸径、树高、材积生长量比中等立地分别大2.3%~25.8%、15.1%~56.4%、27.6%~173.2%;中等立地比差立地大1.0%~53.3%、-9.9%~32.6%、14.0%~155.1%。3种立地上的西南桦不同种源胸径、树高、材积的生长有差异,最大与最小之间差异分别是1.60 cm、1.0 m、0.003 71 m3。

| Abstract: | The growth of 25 provenances of Betula alnoides on three different local sites was observed.The results showed that local site condition has most effective affection on the growth of Betula alnoides.Significant differences were found on the growth of young tree's diameter,height and volume.Diameter,height and volume on good site were 2.3%～25.8%,15.1%～56.4% and 27.6%～173.2% more than those on middle local site,respectively.While diameter,height,volume on middle local site are 1.0%～53.3%,-9.9%～32.6% and 14.0%～155.1% more than those on poor local site,respectively.Comparison of the average growth rate of 25 different provenance diameter,height and volume on three sites,the maximum difference was 1.60 cm,1.0 m and 0.003 71 m3,respectively. |
