“T”形芽接方法简便,技术容易掌握,节省接穗材料,比枝接经济;再者是芽接适用时期较长。应用“T”形芽接法嫁接的砧木,通常选直径粗度在0.6～2.5厘米之间。砧木过粗,皮层增厚,影响成活率。芽片半成苗“跑码”时,在近地面10厘米处嫁接;2～3年生乔砧树“跑码”时,在长成的砧木树上按树形选择枝干,距主 “T ” shaped bud connection method is simple, easy to master the technology to save scion materials, than the branch economy; then the sprouting for a longer period of time. Application “T ” bud graft grafting rootstock, usually selected diameter diameter between 0.6 ~ 2.5 cm. Rootstock too thick, thick cortex, affecting the survival rate. Sprout film seedlings “run code ” when the grafting at 10 cm near the ground; 2 to 3 years Joe rootstock “run code ”, grow in the rootstock tree by tree selection of branches, From the Lord
