一、树体结构与整形:定干高度:60-80cm,干高:40-60cm。树高2.5-3.5mm,冠径3-4mm,中干直立,其上疏散错落分布10-12个小主枝,一般不分层,上下重叠主枝间距50-60cm,下层主枝长1.5-2m,角度70-90度,上层主枝长依次递减,主枝上配备中小型结果枝组。1-5年生幼树整形时,每年选留2-3个位置适中的主枝,于秋季拉成70-90度,轻剪或不剪。中央干要维持一定优势,冬剪时一般留50cm短截。当树高和主枝数达到要求时,中干落头开心,一般五年完成整形。二、修剪技术:1.幼树修剪量占总枝量的10-20%,缓放枝与短截枝比例为10:1。盛果树修量占总枝量的25-30%,缓放枝与短截枝比例为10:3。2.旺树:多缓放、少短截,多留花,拉大
First, the tree structure and plastic surgery: set dry height: 60-80cm, dry high: 40-60cm. Tree height 2.5-3.5mm, crown diameter 3-4mm, dry in the upright, scattered on the evacuation of 10-12 small main branches, generally not hierarchical, up and down the main branch spacing 50-60cm, the main branch of the lower long 1.5- 2m, the angle of 70-90 degrees, followed by decreasing the main branches of the main, the main branch with small and medium sized Zhizu group. 1-5 years old sapling shaping, the annual election to stay 2-3 moderately located main branch, pulled in the fall of 70-90 degrees, with or without cutting. Central to maintain a certain degree of dry, winter shear generally stay 50cm short cut. When the tree height and the main branch to meet the requirements, Zhonggannaotou happy, generally five years to complete the plastic. Second, pruning techniques: 1 saplings trimming the total amount of 10-20%, slow release branch and short branch ratio of 10: 1. Sheng fruit tree repair volume accounted for 25-30% of the total branch, slow release branches and short branches ratio of 10: 3.2. Mong tree: more slow release, less short cut, stay more flowers, larger
