摘要
以马占相思（Acaciamangium）为母本，直干大叶相思（Aauriculiformis）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2～3m，冠幅为3～4m，开花集中在离地面高0．60～1．8m处树冠外围，达到矮化树体、优化树形、便于授粉操作的目的。
Using Acacia mangium as female parent, straight-stem Acacia auriculiformis as male par- ent, 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.
