| 摘 要： | 调查了尾巨桉DH32-29无性系在华南地区及四川盆地部分县市的种植规模、生长表现及冬季耐寒能力。分析发现,湖南衡阳市的气候条件不适合种植DH32-29,广西临桂县、福建龙岩市基本适宜种植,而广西钦州市与扶绥县、广东湛江市、福建漳州市等县市适合种植,是DH32-29主要种植区。该无性系在9个调查地的生长状况有一定差异,以广东湛江市的DH32-29生长最快,4年生林分年平均树高、胸径、单株材积分别达4.3 m.a-1、3.58 cm.a-1、0.0325 m3.a-1。生长差异与年平均气温相关性较大,而与所在地的地理位置、年平均降雨量的相关性小。

| Abstract: | An investigation was carried out into the planting scale, growth status and climatic adaptability ,in- cluding cold- tolerance of E. urophylla x E. grandls clone DH32-29 in southern China and Sichuan Province. Results showed that clone DH32-29 was not well adapted to the climate of Hengyang in Hunan, was marginally well adapted to Lingui in Guangxi and Longyan in Fujian, and was very well ,wJapted to plantation environ- ments in Qinzhou and Fusui in Guangxi, Zhanjiang in Guangdong, and Zlmngzhou in Fujian.The latter locations are all major areas for planting clone DH32-29. Marked differences in gnnvth of clone DH32-29 were observed among the 9 plantation environmentsAocations investigated. The best growth was in Zhanjiang, Guang- dong, where a tree height growth, diameter at breast height growth and single tree volume growth up to age 4 years ranged up to 4.3 m· a-1, 3.58 cm · a-1 and 0.0325 m3 · a-1 respectively. Growth across sites was positively correlated with mean annual temperatures, but the correlations with geographical position and mean annual rainfall were weak. |
