調查証明,基部三主枝邻近半圓形是我省目前生产中較好的一种树形,其整形技术主要是适当降低树高和干高,减少树冠层次和主枝数,加大主枝角度等。在一般情况下,树高宜为4—5米,干高40—60厘米;主枝开張角度50一60°;主枝5—7个,呈2—3层排列;每个主枝上选留2—4个侧枝。树冠之結构应依品种的生物学特性、自然条件和管理措施的不同而合理确定,即因树修剪,随枝作形。
Survey proves that the three main branches near the base of the semicircular shape is the province’s current production of a good tree shape, its plastic deformation technology is mainly appropriate to reduce the height and height, reduce the level of the crown and the main branch, increase the main branch Angle and so on. Under normal circumstances, the tree height should be 4-5 meters, dry 40-60 cm; main branch opening angle of 50 to 60 degrees; main branch 5-7, was 2-3 layers; each main branch Choose 2-4 branches. The structure of the crown should be determined according to the biological characteristics of the species, natural conditions and management measures, that is, the tree pruning, with the branches shape.
