摘　　要：对香樟(Cinnamomum camphora)在不同高度(5、10、20、30、40、50 cm)伐桩的萌芽性能和生长量的差异性进行研究,结果表明:萌芽点数不受伐桩高度影响;桩高为30 cm时萌芽条地径最大;单株平均生物量、萌芽条数、萌芽条高度随着伐桩的增高先增加后减小,且在桩高为20 cm时出现最大值,适合应用于樟树萌芽原料林营造。The bud performance and the difference of growth were studied at different stump heights （5 cm, 10 cm, 20 cm, 30 cm, 40 cm, 50 cm） of Cinnarnomurn carnphora. The results showed that bud points weren＇ t influenced by the stump heights; the diameter of budding strips was the highest when the pile height was 30 cm; average per plant biomass, the number of bud and sprouting height increased followed by decreased with the stump heights and reached the highest when the pile height was 20 cm, which was suitable for application in the construction of raw material forest of Cinnamomum carnphora bud.
