扫帚形基部三主棱角度小，内部透光不良，枝条生长细弱，花芽少，坐果率低，应注意开张主技角度，主枝中、上部多留果；中小于上多留呆；中小平上多留开张形战养技。偏冠树一面枝条较密，一面稀少，可从今C干上进位置合适的枝条或主枝上的侧技补空。主棱角度相差悬殊的偏体树， Broom-shaped base of the three main edge angle is small, poor internal light transmission, weak branches growth, flower buds less, fruit setting rate is low, should pay attention to open the main technical point of the main branch, the upper part of the remaining fruit; Opened fighting skills. Crowberry crown side of the dense, one side sparse, from the current position on the C stem on the appropriate branches or main branches of the side skills fill the air. The main angular difference between the disproportionate partial tree,
