富士苹果的修剪原则是以轻剪为主,适当疏剪,少短截,注意改善树冠光照条件.另外,还应结合夏剪.具体的修剪技术如下:乔砧富士的树形应采用基部三主枝小冠半圆形为好.其结构是树高4米左右,冠径5—6米,主干高50—60厘米,中心干较弯曲,当树体达到高度后,逐步进行落头形成半圆形树冠.全树有5—6个主枝,在中心干上分上下两层排列,两层间距100厘米左右.第一层3个主枝在两年内选留,层内距离40厘米以内,主枝开张角度60—70度.第二层留2—3个主枝,相距40—60厘米.基部三主枝方位角间隔120度,上部各主技与基部主枝插空着生,每个主枝上选留1—2个侧枝.苗木定植后到结果前称为幼
Fuji apple pruning principle is based on light shear, appropriate pruning, less short cut, pay attention to improve the lighting conditions crown.In addition, should also be combined with summer cut.The specific pruning techniques are as follows: Joe Fuji tree should be based on the base three The main branch of the small crown semicircular as well.Its structure is about 4 meters high, the crown diameter of 5-6 meters, the main high 50-60 cm, the center of the dry more curved, when the tree reached a high degree, and gradually drop the formation Semicircular canopy. The whole tree has 5-6 main branches, arranged in the center of the trunk up and down two layers, two layers spacing of about 100 cm. The first layer of three main branches in the two years to choose to stay within the distance of 40 cm Within the main branch opening angle of 60-70 degrees. The second layer to stay 2-3 main branches, 40-60 cm apart. Base three main branches azimuth interval of 120 degrees, the upper part of the main technology and the main branch inserted blank , Each of the main branch to choose to stay 1-2 side branches
