闽南山地桉树种/种源选择试验研究

摘要

闽南山地引种的19个不同桉树种/种源对比试验研究表明，尾巨桉、巨尾桉及广西尾叶桉属高产型树种，年平均蓄积生长量达35.3～53.3 m3*hm-2，其山地造林后表现适应性强、树干圆满通直、林木分化程度低、林相整齐、生产力高，经示范推广收效显著，是闽南山地短周期工业原料林造林的首选树种，值得大力推广引种。%The results of a study on comparing 19 eucalypt species/provenances introduced in hilly land of south Fujian showed that Eucalyptus urophylla × E. grandis, E. grandis × E. urophylla and Kwangsi Timor belong to high-yielding species. The annual mean stand volume of these species reached 35.3～53.3 m3*hm-2　in average. Planted on hilly land, they showed the following characters: strong adaptability, straight and well-developed stem, low differentiation, tidy forest form and high productivity. It is proved that these tree species are of optimal species to meet the demand for shortrotation industrial raw material in south Fujian, and is worth to be introduced and planted widely.
