摘　　要：对柳窿桉9号的适应性试验结果表明:柳窿桉9号适应性和速生性较强,在Ⅲ类地上,其速生性虽略比尾巨桉DH32—29差,但1a生年平均树高可达2.0m以上,2a生树高、胸径分别可达5.0m和5.0cm以上,尤其在低海拔山地不受冻或轻微受冻的情况下,其速生性较为明显且树干通直、径粗,抗风性较强。但柳窿桉9号对低温极为敏感,其耐寒性与尾巨桉DH32-29相当,可耐-2℃左右的低温,适合在闽东南沿海海拔300m以下的山地栽培。Adaptability test result of E. saligna x E. exserta No9 were showed that adaptability and fastgrowth of E. saligna × E. exserta No 9 were stronger in Ⅲ fertility woodland , the fast-growth is not good as E. urophylla × E. grandis DH32-29,but its avaerage tree-high reach above 2.0m in a year, average tree-high and DH reach above 5.0m and 5.0cm after two years . Especially under mountanious region of low-lying altitude and cold exposure invulnerable, its fast-growth was evident , the bole was straighter , DH was bigger and anti-wind was stronger . However , E. saligna × E. exserta No 9 is sensitive to low temperature, its anti-cold is similar to E. urophylla × E. grandis DH32-29. its capability of Anti-cold was about -2℃. The E. saligna × E. exserta No 9 is fit for planting under 300m altitude mountanious region of Fujian southeast coast.
