在果树生产中,有些苹果品种萌芽、成枝力较低,又由于多年甩放,树冠外围长枝多、中短枝少、枝条光秃,树膛空虚、枝组稀少,因而,产量很低.针对这一问题,我们进行了刻芽试验.刻芽是在果树萌芽前,在芽的上方用锯条横拉1刀深达木质部,从而截断下部向上运输的养分和水分,使刻伤下部的芽得到较多的养分和水分、削弱顶端优势,促发分枝. In the fruit tree production, some apple varieties germinate, the branch force is low, but also due to years of rejection, the crown long branches and more branches less short branches bare branches empty tree branches sparse, and therefore, the yield is very low In response to this problem, we conducted a carved bud test carved bud is in the bud before the top of the bud with a saw blade pull a knife deep into the xylem, thus cutting the lower part of the upward transport of nutrients and moisture, so that the lower part of the carved Buds get more nutrients and water, weaken the top edge, triggering branches.
