幼树期此期树体生长旺盛,新梢生长量大,二次枝抽生数量多,树冠迅速扩大,修剪应做到整形和结果兼顾。主侧枝延长头一般留全枝长的2/3进行剪截,并疏除剪口下1～2个二次枝。将密挤枝、交叉枝、重叠枝和徒长枝疏除,控制竞争枝、直立旺枝的生长。对生长中庸、角度开张的发育枝应缓放 Sapling tree growth period during this period, the growth of new shoots, secondary branch pumping a large number of rapid expansion of canopy, trimming should be done to achieve both the results and results. The main branch extension head generally stay 2/3 of the whole branch length cut, and sparse cut under 1 to 2 secondary branches. Will be dense crowded branches, cross branches, overlapping branches and leggy sparse, control competition branches, upright branches growth. On the growth of the golden mean, the development of open branches should be slowed
