中文摘要 | 本研究引進20種桉樹類樹種分別在臺灣4個地區進行造林適應性試驗。結果寶華試區於造林6個月後因地層滑動、崩坍,致成活率急速下降而受損,礁溪試區則於4年生時遭颱風摧殘後放棄,均未再進行調查;礁溪試區之4年生桉樹以玫瑰桉X尾葉桉雜交種表現最佳;六龜試區之1年4個月生雪梨藍桉、玫瑰桉X尾葉桉雜交種及尾葉桉受一點蝙蝠蛾為害情形較嚴重,均達10.4%以上,至6年4個月時之林木生長表現以玫瑰桉X尾葉桉雜交種、玫瑰桉、尾葉桉及雪梨藍桉較佳,平均樹高為11.20 m、10.42 m、 10.02 m、10.06 m,平均胸徑為11.56 cm、10.74 cm、10.66 cm、11.75 cm,存活率為52.22%、43.89%、53.33%、40.00%;電光試區之5年8個月生林木生長表現以藍桉、玫瑰桉、雪梨藍桉及尾葉桉較佳,平均樹高為11.50 m、 11.57 m、9.87 m、9.37 m,平均胸徑為10.76 cm、10.74 cm、9.15 cm、0.09 cm ,存活率為63.54%、48.96%、63.54%、73.96%。若排除蟲害及颱風之影響因素,則玫瑰桉X尾葉桉雜交種為最具潛力之樹種。 |
英文摘要 | Twenty Eucalyptus species were introduced into the Chiaohsi, Bauhua, Tienkuan, and Liukuei areas of eastern and southern Taiwan to test their adaptability. The trial plantation at Bauhua was destroyed by land creep which occurred within six months after planting, and that at Chiaohsi was heavily damaged by a typhoon at 4 years of age. E. grandis X E. urophylla was the best plot at the 4- year-old Chiaohsi site. Over 10.4% of the trees of E. saligna, E. grandis X E. urophylla and E. urophylla stem damage caused by Endoclyta sinensis had at 16 months at Liukuei. At Liukuei, the average heights of 6.3-year-old E. grandis X E. urophylla, E. grandis, E. urophylla, and E. saligna reached 11.20 m, 10.42 m, 10.02 m, 10.06 m respectively, and the average DBH of these trees reached 11.56 cm, 10.74 cm, 10.66 cm and 11.75 cm respectively, with their survival rate being 40%-53%. At Tienkuan, the average heights of 5.6-year-old E. globulus, E. grandis, E. saligna and E. urophylla reached 11.50 m, 11.57 m, 9.87 m and 9.37 m respectively and the average DBH of these trees reached 10.76 cm, 10.74 cm, 9.15 cm and 9.09 cm respectively, with their survival rate being 49-74%. If pest and typhoon damages are excluded, E. grandis X E. urophylla performed best in Taiwan. |
