摘　　要：根据湖南桉树引种栽培实践,把湖南桉树引种栽培划分为4个主要发展阶段,总结了近10多年湖南桉树研究和推广应用进展,明确提出了中试推广的主要种类有:邓恩桉、赤桉、巨桉、柳桉和巨尾桉。从耐寒桉树速生丰产原理入手,应用遗传控制、立地控制和林分结构控制,提出了耐寒桉树速生丰产栽培配套技术模式。提出了加强现有林保护管理,扩大繁殖系数,有计划地组织推广,加强品种改良研究工作的具体目标。In Hunan Province four developing stages of Eucalyptus have been divided for introduction and cultivation. The study of Eucalyptus and its popularization in the past 10 years has been summarized.Several main varieties are being used for middle testing: E.dunnii maaiden,E.camaldulensis,E.grandis, E.saligna Sm and E.grandis X urophylla.Tests on rapid growth potential and hign yield of Eucalyptus for cold resistant conditions were run along with the development of a relative cultivation technology model based on heredity. The site and stand structure were controlled.Finally,the basis for enhancing stand protection, enlarging breeding coefficient,practicing planned dissemination and improving the breed further is suggested.
