苹果树夏季整形,技术简单、成形快、结果早,在定植后当年可以成花,次年见果,三年可完成整形。现将该方法典型树形的基本特征及其整形方法简介如下: 一、树形的基本特征 成形树高度2.0～2.5米,主干高度50—60厘米。全树共10—12个主枝,分三层分布,第一层4—6个,第二层3—4个,第三层2—3个。一、二层间距50—60厘米,层内距20—30厘米,二、三层间距40—50厘米。主枝开角90—100°角呈单轴延伸,三层主枝枝轴 Apple tree summer plastic surgery, technology is simple, fast forming, early results in the year after planting can be spent, see the fruit the following year, three years to complete the plastic. Now the basic characteristics of the method of typical tree and its shaping method is as follows: First, the basic characteristics of the tree height of 2.0 to 2.5 meters forming trees, trunk height of 50-60 cm. The whole tree a total of 10-12 main branch, divided into three layers, the first layer 4-6, the second layer 3-4, the third layer 2-3. First, the second floor spacing of 50-60 cm, the layer spacing of 20-30 cm, two, three-spaced 40-50 cm. The main branch angle 90-100 ° was uniaxial extension, three main branches axis
