果树优良品种都是用芽接或枝接繁殖的。一般枝接都是在春季砧木发芽时期,时间比较短,接时又得涂蜡、封土等手续繁杂,还不利于伤口愈合,且成活率也不高;芽接时期虽较长,但砧木剥不开皮时不能嵌入接芽则无法嫁接。文化大革命后,科技人员走与工农相结合的道路,对嫁接技术进行了改进,通过多次试验,创造了一种新的嫁接方法,从春到秋只要接口能愈合时均可嫁接,克服了旧法中存在的各种缺点,并且简化了操作程序,成活率很 Good varieties of fruit trees are budding or branch propagation. General branches are in the spring rootstocks germination period, a relatively short time, then have to wax, sealing and other procedures complicated, is not conducive to wound healing, and the survival rate is not high; budding period though longer, but rootstock peel When the skin can not be embedded in the bud can not be grafted. After the Cultural Revolution, scientists and technicians took the road of combining with workers and peasants and improved the grafting technology. Through many experiments, a new grafting method was created, which could be grafted from spring to autumn as long as the interface could heal The old law exists in a variety of shortcomings, and simplifies the operating procedures, survival rate is very high
