我判断可能有如下两个原因: 1.梨树的接穗选择,与苹果不同。苹果的枝组稍偏弱一点是可以利用嫁接的,一般都有较高的成功率。而梨树的接穗,必须选择生长势强,枝组粗壮的接穗或带少量花芽的枝组才易嫁接成活,对于鸡爪状花枝是不宜作快速成形的材料。估计是选用了弱枝梨接穗而失败。
I judge may have the following two reasons: 1. Pear scion selection, and Apple is different. Apple branch group slightly weaker can use grafting, generally have a higher success rate. The scion of pear, we must choose a strong growth potential, sturdy branch group or with a small amount of flower buds branch group is easy to graft alive, for the chicken claw flowering is not suitable for rapid prototyping materials. It is estimated that the selection of weak branches scion and failure.
