芽接是果树生产中应用最为普遍的一种嫁接方法。实践证明,在芽接过程中只要采取以下几项技术措施,一般成活率均会达90％以上。 (1)适时芽接。芽接在春、夏、秋三季均可进行,但以夏、秋两季最为适宜。夏接过早,接芽发育尚未充实,砧木又处于旺长阶段,体内积累养分较少,成活率低。并且接芽当年萌发后,在北方地区,易发生冻害。秋接过晚,生理机能减弱,不易离皮,愈合困难,也影 Budding is the most common application of fruit tree grafting method. Practice has proved that as long as the sprouting process to take the following technical measures, the general survival rate will reach 90%. (1) timely budding. Bud in the spring, summer and autumn can be carried out in three seasons, but summer and autumn are most suitable. Summer took over early, then bud development has not yet been fulfilled, rootstocks are in the long stage, the accumulation of less nutrients in the body, low survival rate. Bud then germinated in the northern region, prone to frost damage. Autumn took late, weakened physiological function, easy to leave the skin, healing difficulties, also shadow
