| 摘 要： | 在仙游县书峰片区营造的110 hm2降香黄檀幼林分中设置不同坡向、坡位的固定观测样地,对幼林的生长习性、适应性和抗逆性进行定位观测与调查分析.结果表明,①降香黄檀在引种地表现出较强的适应性和速生性,且树高和胸径分别于第二年、第四年开始进入速生期,5 a生幼林树高、胸径年均生长量达到或接近广东、广西或海南丘陵台地栽培的生长速度,有一定的抗寒能力,幼林可抗-3℃低温;②一个生长年内的生长特性显示出其生长与蒸发量、气温等气候因子密切相关,表现为11~3月为休眠期,5月开始加速生长,6~7月为树高生长高峰期,7~8月为径生长高峰期;③坡向对幼林有显著影响,是制约林分生长的主导立地因子,坡位对幼林生长影响不大.

| Abstract: | In Sufeng area of Xianyou county,fixed observation plots in different slope-direction and slope-position have been set in 110hm2 young Dalbergia forest to observe and analysis young Dalbergia's growth habit,adaptability and resistance.The results showed that:(1) In the introduction location,adaptability and growth speed of young Dalbergia were strong.The second and fourth year were fast growing period for growing height and DBH of Young tree,and the height and DBH of 5a young trees were near the average ann... |
