用枝条作接穗材料的嫁接方法称枝接。通常有切接法、劈接法、腹接法、靠接法等多种方法。枝接是用母树枝条的一段(枝上须有1~3个芽),基部削成与砧木切口易于密接的削面,然后插入砧木的切口中,注意砧穗形成层对体吻合,并绑缚覆土,使之结合成活为新植株。

这条的规律可以简单描述为:如果一根树干分叉为两个树枝,那么两个树枝的横截面积之和等于树干的横截面积;如果树枝接着分别分叉为两根小树枝,那么这四个次生分枝的横截面积总和仍等于树干的横截面积……依此类推。
If those two branches in turn each split into two branches, the area of the cross sections of the four additional branches together will equal the area of the cross section of the trunk. And so on.
