一、前言桉树原产澳洲,自1744年引入欧洲后,由于生长迅速,适应性强,用途广泛,世界各国竟相引种。目前已有100多个国家引种栽培,面积约占世界人工林的1/5强。如今,许多桉属树种已成为世界性的造林树种。由于广泛的引种栽培,经过驯化,杂交,杂种变种很多,六十年代报道的桉树就超过1000种以上。桉树最早(1890年)由西欧引入两广,1894年福建开始引入野桉(Eucalyptus rudis),现有90多年历史。闽南的漳州市南坑在1919年引种赤桉(E.camaldulensis),1929年长泰县戴墘村引种过柠檬桉(E.citriodora),1935年漳州市和漳浦县大南坂引
I. Introduction Eucalyptus originated in Australia, since its introduction into Europe in 1744, due to its rapid growth, strong adaptability and wide range of uses, all countries in the world actually introduced it. At present, more than 100 countries have introduced and cultivated about one-fifth of the world’s plantation. Today, many eucalyptus species have become afforestation species worldwide. Due to a wide range of introduced cultivation, after domestication, hybridization, many varieties of hybrids, more than 1000 species of eucalyptus were reported in the 1960s. Eucalyptus was first introduced to Western Guangxi by Western Europe in 1890. In 1894, Fujian began to introduce Eucalyptus rudis, which is more than 90 years old. Introduction of E.camaldulensis in 1919 in Nankeng of Zhangzhou City in southern Fujian Province, introduction of E. citriodora in Daijian Village of Changtai County in 1929, introduction of Dainanram in Zhangzhou City and Zhangpu County in 1935
