果树种或品种利用枝或根获得自根苗木做为栽植材料,不仅可以保持优良种性,而且可以排除由于砧穗之间相互影响所带来一些不需要的性状。自根苗果树在生产上表现出树势生长整齐健壮的特点,而且不出现由于嫁接所引起的病毒性感染等病害。因此在国际上日趋受到重视并大力进行试验研究。目前已有苹果、桃等种果树利用自根苗建园投产。关于桃品种利用枝插生根的试验工作, The use of branches or roots of fruit trees or cultivars to obtain self-rooted seedlings as planting material not only maintains good seed quality but also eliminates unwanted traits caused by the interaction between rootstocks. Since the root seedlings of fruit trees in the production of trees showing tidy and robust growth characteristics, and does not appear due to graft caused by viral infections and other diseases. Therefore, the international community has drawn increasing attention and vigorously conducted experimental studies. At present, there are apples, peaches and other kinds of fruit trees built with the use of self-rooted garden production. Peach varieties on the use of sticks inserted root test work,
