桉树是我国外引最成功的主要树种之一,在我国南亚热带地区解放以来广泛推广栽植,建立了较大面积的按树人工林基地,但现阶段营建的桉树人工林生长量还很低,一般年生长量为0.3立方米/亩。为了解决适地适树适种源问题,进一步提高桉树造林生产力,中国林科院于一九八三年将桉树种源引种试验列入了“六五”国家重要造林树种良种选育攻关课题计划。一九八四年全国桉树科技协作组承担林科院下达本课题计划,由全国桉树协作组统一部
Eucalyptus is one of the most successful major tree species in China. Widely popularized and planted in the south subtropics of our country and established a large-scale tree-planting plantation base, the growth of eucalyptus plantations built at this stage is still very low, The average annual growth of 0.3 cubic meters / mu. In order to solve the problem of adapting to the suitable source of suitable trees and further improving the afforestation productivity, the Chinese Academy of Forestry put the introduction test of eucalyptus provenance into the “Sixth Five-Year Plan” project of major afforestation species breeding in 1983 . In 1984, the National Collaboration on Eucalypt Sci-tech Cooperation undertook the plan assigned by the Academy of Forestry Science and Technology, which was coordinated by the Unified Eucalyptus Collaboration
