【摘要】 在浙江丽水开展邓恩桉、赤桉、柳桉、巨桉、尾巨桉的引种栽培试验,结果表明,参试品系的耐寒性强弱表现为邓恩桉>赤桉>柳桉>巨桉>尾巨桉;邓恩桉的幼树高生长和径生长各参数均高于其他几个参试桉树品系,表现出明显的生长优势;不同品系间的树高、胸径存在显著或极显著的差异,其中以邓恩桉的生长量最高,4年生时胸径和树高分别达15.14cm、11.14 m。邓恩桉适合作为速生工业原料林树种在丽水发展。更多还原

【Abstract】 Cultivation experiment was made in Lishui,Zhejiang for introducing Eucalyptus dunnii,E.camaldulensis,E.saligna,E.grandis and E.urophylla grandis.Cold resistance disparity of the experimented species showed,E.dunnii>E.camaldulensis>E.saligna>E.grandis>E.urophylla grandis;E.dunnii young tree height growth and diameter growth parameters were higher than other tested varieties.It showed the evident growth dominance.There was evident or extremely evident difference between the height and dbh of different varieties,the growth of E.dunnii was highest,The dbh and height reached 15.14 cm and 11.14 m at the age of 4.It was suitable to expand in Lishui as fast growing tree species for industrial material plantation.更多还原
