芽的差异与管理芽的分布和特征桃树枝条上多着生复芽,其中双芽者多为一个花芽一个叶芽,三芽或四芽者,中间一芽是叶芽,其余是花芽。梨树枝条上多着生单芽,它或是叶芽或是花芽,但芽基部多形成副芽,发育较好,寿命较长,当主芽受伤或受刺激后能萌发抽枝。桃树是纯花芽,侧生于新梢叶腋内,翌春萌发后直接开花,不抽生枝叶,由于枝梢顶端很少形成花芽,有利于短截修剪。梨树是混合花芽,常形成鸡爪状短果枝群,春季有的先抽枝展叶,再在新梢上开花结果;也有的先开花后展叶成年梨树枝梢 Differences and management of buds Distribution and characteristics of buds There are many buds on the branches of peach branches. Among them, two buds are mostly one bud, one bud or three buds, the middle bud is leaf bud, and the rest is bud. Pear branches more than single buds, it is leaf buds or flower buds, but buds more than the formation of secondary bud base, better development, longer life expectancy, when the main bud is injured or stimulated after germination shoots. Peach is a pure flower bud, side was born in the axillary axillary foliage, the next spring after the bloom flowering directly, not pumping branches, the tip of the shoots rarely form flower buds, is conducive to short cut pruning. Pear is a mixture of flower buds, often forming chicken claw short fruit branches, some spring in the first branch exhibition leaf, and then the flowering results on the shoots;
