1、轮生枝过多。在基部轮生4～5个枝,造成树体掐脖现象,导致树体中心干细弱,影响树体生长势。解决办法:把轮生枝中的1个下部枝疏除,1个重回缩,再把其余2～3个枝压下拉平。2、定干过高。苹果树定干高度超过120厘米,树干下部光秃,树体长势较弱,成形晚,不利于早期丰产。解决办法在 1, turn twigs too much. In the base of rotation 4 to 5 branches, causing the phenomenon of pinch neck tree, resulting in thin stem center of the tree, affecting the growth potential of trees. The solution: the rotation branches in the lower branches of a sparse, a heavy retraction, and then the remaining 2 to 3 branches pressed flat. 2, set dry too high. Apple trees set dry height of more than 120 cm, the lower part of the trunk bare, tree growth is weak, forming late, is not conducive to early high yield. The solution is
