| 摘 要： | 雷州林业局是我国第一个以桉树为主营树种的林业单位,50余年来一直以桉树的种植、加工、利用和出口为核心业务。依靠桉树新品种培育等成果,雷州林业局的桉树生长量由1990年代初的10m3·hm-2提高到2002年的20m3·hm-2,在同行业中保持强的竞争力。本文从桉树种质资源的收集、矮化杂交圃的建立、人工杂交技术等方面简述了雷州林业局以杂交育种为主的桉树育种资源研究、利用工作,分析了存在的问题和解决的办法。

| Abstract: | Leizhou Forestry Bureau is the first unit to trade mostly in eucalypt us and have been dealing in planting, processing, utilizing and exporting of e ucalyptus for more than 50 years. The MAI（mean annual increment） of eucalyptus was raised from 10 m3·hm-2 in 1990 to 20 m3·hm-2 in 2002 by using research results such as breeding new species, which makes it continue to be competitive in forestry. Eucalypt cross breeding of Leizhou Forestry Bureau was outlined fr om collection of genetic resources, building nursery for dwarf, artificial hyb rid techniques, etc. The existing problems and solving methods were put forward . |
