| 摘 要： | 以马占相思(Acacia mangium)为母本,直干大叶相思(A.auriculiformis)为父本,通过亲本选择、容器砧木的培育、本砧嫁接、矮化修剪等技术手段培养相思杂交亲本,可控制亲本树冠高度为2~3 m,冠幅为3~4 m,开花集中在离地面高0.60~1.8 m处树冠外围,达到矮化树体、优化树形、便于授粉操作的目的。

| Abstract: | Using Acacia mangium as female parent,straight-stem Acacia auriculiformis as male parent,through parents selection,cultivation of rootstocks with container,grafting and dwarfing,crossing parents of Acacia were cultivated.The controllable crown height of parents was 2～3 m,crown size was 3～4 m,and flowering focused on out crown at the height of 0.60～1.8 m,in order to dwarf trees,optimize shape,and be easy to pollination. |
