    要识别真假银杏嫁接苗。嫁接银杏树苗批发广东快乐十分走势图可促进早结果,即3-5年即可挂果,不到10年便可形成效益,因此有人用实生苗冒充嫁接苗,在引种或购买时应学会区别。其方法是,一看接茬。在嫁接苗的砧木和接穗之间,有一个虽已愈合但仍明显的接茬。即使是芽接,也会在插入接穗芽的地方,明显留下一个瘤状伤疤。如果苗木无此特征,就一定不是嫁接苗。也有人把实生苗先平地剪伐,促使剪口下的潜伏芽萌发的枝条向外延伸生长,或者在实生苗的某一部分深切一刀,使其愈合后形成伤疤,以假乱真,但只要留意观察,便会发现其伤痕处并无任何嫁接痕迹,更没有枝条抽生。二看枝条。真正的嫁接苗,从接茬上端或瘤状伤痕中抽生出来的枝条,一般是斜生向外延伸,生长健壮、充实。当然,也有用顶芽做接穗的劈接苗,抽生的枝条会直立向上生长。不过,一个用作接穗的枝条,可以剪成多个接穗,而顶芽只有一个,这种直立向上生长的嫁接苗很少。三看叶片。真正的嫁接苗,叶片厚实,呈深绿色,少裂缺。而从实生苗上采摘嫁接的假嫁接苗,叶色黄,芽瘪、细弱、顶端直立向上,叶片深度裂缺。
