芽接是经济利用接穗,伤口少,成活率高,嫁接时期长的一种嫁接方法。生产上繁殖苗木,改劣换优,高接换头常采用此法,影响芽接的成活因素很多,关键是:1.掌握好嫁接的时期。适宜芽接的时间较长,春、夏、秋三季砧木“适合剥皮”时均可进行。但成活率最高的是秋季(除核桃、枣树),即七月下旬至九月初。因这时嫁接的芽,当年不能萌发,有利越冬。过早接芽当年萌发,生长不充实,冬季易冻死;过晚砧木不易剥皮,接芽不易取,接后愈合困难,不易成活。2.把好接芽关。接芽是成活
Budding is the economic use of scion, less wounds, high survival rate, a long period of grafting method of grafting. The production of breeding seedlings, mercurial vapor pas cher, mercurial vapor pas cher, mercurial vapor pas cher, mercurial vapor pas cher, mercurial vapor pas cher, mercurial vapor pas cher, mercurial vapor pas cher, mercurial vapor pas cher, mercurial vapor pas cher, high replacement head often use this method, budding survival many factors, the key is: 1. Grasp the grafting period. Suitable for budding a longer time, spring, summer and autumn rootstock “suitable for peeling ” can be carried out. But the highest survival rate is the fall (except walnut, jujube), that is, from late July to early September. Grafted buds at this time, when the germination can not be conducive to wintering. Premature bud germination, growth is not sufficient, the winter is easy to freeze dead; late rootstock is not easy to peel, the bud is not easy to take, and then difficult to heal, not easy to survive. 2. Good buds off. Bud is to survive
