摘要
介绍了贵州省桉树的引种现状、存在问题和发展对策。贵州省引种桉树栽培成功的限制因子是寒害,主要表现为持续时间较长的低温和凝冻气候;在贵州成功引种保存的桉树种质资源基础上开展耐寒选育,是桉树能否在贵州省扩大种植的关键技术措施;贵州省桉树发展存在的主要问题是受地势和气候的影响,适宜规模化经营造林的面积较少,确定适宜种植区和种植规模应采取稳步推进的策略。
The limiting factor for the successful introduction of Eucalyptus in Guizhou is the cold damage, thus the could-resistance breeding based on the existing successful provenances of Eucalyptus is the key technique for its expanding plantation in Guizhou. The suitable area for the intensive plantation and management of the eucalyptus in Guizhou is limited, thus the development strategy should be conservative.
