调整果树品种结构,进行改接换头是一种周期短、见效快的好方法。但在生产中应用时,应对几个关键环节多加注意,否则会导致诸如高接病、不亲合等问题发生,给生产带来很大损失。一、树龄和枝龄的选择尽量选用树龄、枝龄小的健壮树做砧木。树龄以十年内为宜,以1～2年生枝段为主要嫁接砧木。二、砧穗的亲合性一般以共砧嫁接为宜。但桃可作李子、樱桃、杏梅的砧木。杏可作李子、樱桃、杏梅的砧木。桃上接杏虽可成活,但后期易表现不亲合。杏上接桃,亲合性差。
Adjust the fruit tree species structure, change the head is a kind of short cycle, a good quick way. However, when applied in production, pay more attention to several key links, otherwise it will lead to such problems as high incidence of illness and non-affinity, which will bring great losses to production. First, the age of the tree and the choice of age as far as possible selection of tree age, small branches of sturdy trees to do stock. Tree age to ten years is appropriate to 1 to 2-year-old branches as the main rootstock grafting. Second, the affinity of the scion Ear of common anvil grafting is appropriate. But peach can be used as plum, cherry, apricot plum rootstock. Apricot can be used as plum, cherry, apricot plum rootstock. Although the peach apricot can survive, but the late performance is not affinity. Apricot pick peach, poor affinity.
