近年来,在矮化密植栽培过程中不论采用自由纺垂形,还是自然圆柱形,均要求把枝条角度开张到70～80度。这对解决冠内光照,缓和树势,促进幼树早丰产及提高果实品质均有良好的效果。现在生产中开张角度一般采用“拉绳”的 In recent years, in the process of dwarfing and close planting, whether using the free spinning vertical or the natural cylindrical, it is required to open the branch angle to 70 to 80 degrees. This is to solve the crown of light, ease the tree vigor, promote sapling early yield and improve fruit quality have a good effect. Opening angle is generally used in production now “pull rope.”
