巨桉引种栽培及适生区域的研究

Researth on Introduction of Encalyptus grandis and its normal region

本文概述了巨桉在四川引种栽培后的适应性和生长量。巨桉在四川生长迅速、发育正常，年蓄积生长在１８ ｍ ３／ｈｍ ２～２２．５ ｍ ３／ｈｍ ２，６ 年～８ 年可培育出工业纤维原料，在相同的立地上，与其它树种相比，培育周期短、产量高、效益好，是培育短周期工业纤维林的好树种。在栽培试验的基础上，运用生物气候预测法，研究巨桉在四川的适生区域，结果表明：四川盆地、盆边低山区以及川西南山地局部地方可以栽培推广巨桉。

The adaptation and increment of Encalyptus grandis were described after its introduction and cultivation in Sichuan.It had an increment of 18 m 3/hm 2 to 22.5 m 3/hm 2,and thus it can be used as an industrial fiber material after six to eight years of cultivation.In addition,researches were made into the normal regions of E.gramdis in Sichuan in this paper.
