果树迹地11个桉树无性系前期生长比较

Early Growth Comparison of 11 Fast-growing Eucalyptus Clones in the Cutover Land of Fruit Tree

在果树迹地引种11个速生桉树无性系进行比较试验,初步显示热带北缘地区前期速生的无性系有广林4、DH22、DH201-2,为果树残林更新种植速生丰产桉树无性系选择提供技术依据。

A comparative trial of 11 fast-growing eucalypts clones planted on the cutover lands of fruit tree was performed, the results suggested that Guanglin 4, DH_ 22 and DH_ 201-2 were fast-growing clones at the north area of tropical at earlier stage, and it can be afforded for degraded fruit tree lands to be replanted with fast-growing and high-yield eucalyptus clone.
