为了保持丰产的树体结构,使树冠各个部位生长均衡,全面均匀挂果,产量稳定,必须及时修剪调整果树树体各部位生长势,其方法如下: 1.利用分枝角度的大小调整 枝条角度小长势强,可采用撑枝、拉枝、压枝等方法开张枝条的夹角,并用里芽外蹬剪截、背后枝换头等方法,使枝条长势缓和;如果枝条长势弱,可以留上芽剪截,或用长势强的枝条代替弱枝,或缩小弱枝着生处的角度(基角角度),均可使弱枝的长势增强。 2.抑强扶弱调整 主枝与主枝间、主枝本身的前部和后部,若长势不均衡时,可疏剪过旺枝 In order to maintain a high yield structure of the tree body, so that all parts of the crown growth balanced, full and uniform fruiting, stable output, the tree must be trimmed in time to adjust the growth potential of various parts of the tree, the method is as follows: 1. The use of branch angle to adjust the small branches angle Growing strong, you can use the sticks, pull branches, pressure sticks and other methods of opening the angle between the branches, and with the bud outside the cut cut off the back of the stick for the first method to make the branches ease; if the branches grow weak, you can leave bud and shear Cut, or with strong branches instead of weak branches, or narrow the weak branches at the birth angle (base angle), can make weak branches growing. 2. Strengthen the weakness and weakness Adjust the main branch and the main branch, the main branch of the front and rear, if the growing imbalance, you can sparse excess branch
