桃树苗为什么要嫁接

时间:12-04-12来源: 作者:果树网 收藏

桃树苗嫁接就是将欲繁殖的枝条或桃树苗接在另一种植物的茎或根上,使两者结合成为一体,形成一个独立新植株的繁殖方法。通过嫁接所得到的苗木称为“嫁接桃树苗”,它是一个由两部分组成的共生体。供嫁接用的枝或树苗成为“接穗”,而承受穗带根的植物部分称为“砧木”。用桃树苗枝条做接穗的称为“枝接”,用芽做接穗的称为“芽接”。
  嫁接繁殖是桃树苗培育中一种很重要的繁殖方法,它除具有一般营养繁殖的优点外,还具有其他营养繁殖所无法起到的作用。但是桃树苗嫁接繁殖也是有一定的局限性和不足之处,例如,嫁接繁殖一般限于具有亲缘关系的植物,要求砧木和接穗的亲和力强,因而有些植物不能用嫁接方法进行繁殖,单子叶植物由于茎构造上的原因,嫁接较难成活。
