1、仙游县降香黄檀栽培适应性调査分析摘要:在仙游县书峰片区营造的110hm[sup]2[/sup]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,?降香黄檀在引种地表现岀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,5a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;?一个生长年内的牛长特性3月为休眠期,5月开始加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,速生长,6,7月为树高生长高
2、峰期,7,8月为径生长高峰期;?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.关键词:降香黄檀;引种栽培;适应性;抗逆性;生长习性仙游县中图分类号:S792.28S718.5文献标识码:A文章编号:1671-3168(2011)03-0011-04AclaptabilityInvcstigationonDalbergiaIntroductionandCultivationinXianyouSUJian-hua(ForestryBureauofXianyouCounty,Xianyou,Fujian351200,China
