苍溪雪梨萌芽力强,幼树成枝力较强,盛果后易形成短果枝群结果,原有的主要树形疏散分层形枝条从属关系易混乱,对幼树强旺树势调整不力,树冠内部易郁闭,光合利用率不高,农事操作不易,用工多。而采用自由纺锤形树形则可以克服其缺点。自由纺锤形主干高60—80cm,中心干直立,可以解决其干性强,易旺长的问题。在中心干上均匀排列15—20个呈螺旋状自由错位插空排列的主枝。主枝上没有明显侧枝,在主枝上直接着生以短果枝为主,中、长果枝为辅的结果枝组。
Cangxi Sydney budding strong, strong young branch force, full of fruit is easy to form short fruit branches after the results of the original tree-shaped evacuation delamination-shaped branches afflicted easily chaotic young strong tree vigor adjustment poor Canopy easily inside the canopy, photosynthetic utilization is not high, agricultural operations is not easy, more labor. The use of free spindle-shaped tree can overcome its shortcomings. Free spindle spindle high 60-80cm, the center dry upright, you can solve the problem of its strong dry, easy to prosper. In the center of the dry evenly arranged 15-20 spiral misplaced interspace insertion of the main branch. There are no obvious branches on the main branch, and the main branch is directly connected with the fruit branches with short branches, and the middle and long branches.
