目前,在苹果苗定植后,流行着一种以拉代剪的定干方法。具体做法是:对定植的苹果苗整形带内选出5—8个质量较好的芽子,分别进行目(刻)伤、深达木质部(促其萌生长枝),然后将整形带以上的枝梢不剪拉平。这样做的好处是:保留了较多的枝芽数量,增加了生长期的营养面积,提高了树体的光合效能,幼树的冠径和干周较常规定干法增长较快,从而为早结果奠定了基础。拉平部分可以作为辅养枝在第2年采取夏剪措施,促其形成花芽,以利于早结果。以拉 At present, after the apple seedlings are planted, there is a method of setting the stems by pulling the cut. The concrete method is as follows: 5-8 good quality buds are selected in the plastic belt of the planted apple seedling, respectively carrying the head (engraving) injury, reaching the xylem (promoting the growth of the branch), and then placing the above Branches do not cut flat. The benefits of this approach are: retained more number of branches and shoots, increased nutrient area during growth and increased the photosynthetic efficiency of the tree, the crown diameter and dry week of saplings grew faster than the conventional dry method, thus Early results laid the foundation. Leveling part can be used as a supporting branch in the first two years to take summer cut measures to promote the formation of flower buds in order to facilitate early results. To pull
