| 摘 要： | 邓恩桉是一种抗寒性良好的速生树种。对建阳市不同代表性地段邓恩桉幼林(年龄在1-3 a)生长规律进行了研究。结果表明:邓恩桉幼林个体间的生长差异较大,3年生的幼林的胸径最大值与最小值分别为15.4和1.2 cm,树高最大值和最小值分别为15.8和2.6 m。1-2龄的邓恩桉生长迅速,胸径平均超过3.8 cm,树高平均超过4.2 m。不同立地条件下,阳坡的幼林长势相对较好。

| Abstract: | Eucalyptus dunnii Maiden is a kind of fast-growing tree species with good cold resistance.The young plantation growth rhythm was studied based on investigating E.dunni young plantations(the average age was between 1 and 3) in different places in Jianyang.The results showed that the growth difference among young ones of E.dunni was big.For example,the maximum and minimum value of 3 years-old trees′ diametere breast height(DBH) was 15.4 and 1.2 cm,respectively as the maximum and minimum value of tree height was 15.8 and 2.6 m,respectively.From the first to the second year,the young trees grew fast,as the DBH was over 3.8 cm and the tree height was over 4.2 m averagely.Moreover,the young trees grew well on sunny slopes comparatively. |
