摘　　要：通过对海拔400、600、750、900m四个不同海拔高度的10年生油茶林调查.结果表明:油茶的树高生长量随海拔升高逐渐减小,在海拔300m时平均树高是2.66m,在海拔900m平均树高是2.15m;海拔300m时油茶开花株率的平均多、中开花株率占63.33%,海拔600m时的平均多、中开花株率占43.33%,当海拔达750m时的平均多、中开花株率仅占23.33%;海拔300m时油茶挂果株率的平均多、中挂果株率占56.67%,海拔600m时的平均多、中挂果株率仅占26.67%,当海拔达900m时的平均多、中挂果株率仅占10%.结果认为,海拔300~600m之间的油茶生长量、开花株率、挂果株率最佳,适宜在油茶生产上应用.Through the investigation of 10-year-old Camellia oleifera forests at different altitudes of 400,600,750 and 900 m.The results showed that the tree height growth rate of Camellia oleifera gradually decreased with the increase of altitude,the average tree height was 2.66 m at 300 m altitude,and the average tree height was 2.15 m at 900 m altitude,the average flowering plant rate of Camellia oleifera accounted for 63.33%at 300 m altitude,the average flowering plant rate of Camellia oleifera accounted for 63.33%,the average flowering plant rate at 600 m altitude accounted for 43.33%,and the average flowering plant rate at 750 m altitude accounted for only 23.33%.At an altitude of 300m,the plant rate of Camellia oleifera accounted for 56.67%,at an altitude of 600 m,the plant rate of medium hanging fruit accounted for only 26.67%,and when the altitude reached 900m,the rate of medium-hanging fruit accounted for only 10%.The results concluded that the growth rate,flowering plant rate and hanging fruit plant rate of Camellia oleifera at an altitude of 300~600 m were the best,which was suitable for application in the production of Camellia oleifera.
