前言我国引种桉树已有80多年的历史,解放前只另星栽植,解放后在毛主席革命路线指引下获得了大量的发展,目前分布于南方15省(区)市,种类达200多种。它生长迅速,适应性强,分布范围广,经济价值高,种间易于杂交。同一种内不同的群体或个体之间,性状上存在较大的差异。这些特点,给桉树的良种选育和杂种优势的利用提供了极为有利的条件。选择优树必须以毛泽东思想为指导,用辩证唯物主义的观点,将那些具有优良遗传性状的类型和单株鉴别出来。
Introduction Eucalyptus was introduced for more than 80 years in our country. Before the liberation, only another star was planted. After the liberation, a great deal of development was made under the guidance of Chairman Mao’s revolutionary line. At present, it is distributed in 15 provinces (autonomous regions) in the south with more than 200 species. It grows rapidly, adaptability, distribution of a wide range of high economic value, easy to hybrid between species. Within the same group of different groups or individuals, there is a big difference in traits. These characteristics provide extremely favorable conditions for the breeding of eucalyptus seeds and the utilization of heterosis. Choosing the best tree must take the guidance of Mao Zedong Thought and distinguish the types and individuals with excellent genetic traits from the perspective of dialectical materialism.
