我国利用嫁接法繁殖果树已有二千多年历史。嫁接法是把准备繁殖的果树的枝或芽嫁接在另一株树上,人們称被接的树叫“砧木”,接在上面的枝或芽叫“接穗”。近代,在嫁接过程中,有人发現:有些砧木能使嫁接在它上面的“接穗”长成的树体极度縮小,变成果树中的“矮子”,这种砧木人們又称为它“矮化砧”。一般的果树都有5—8米高,可是利用“矮化砧”繁殖的 China has used the grafting method to propagate fruit trees for more than 2,000 years. The method of grafting grafts the branches or buds of fruit trees that are to be propagated to another tree. People call the received tree an “anvil tree,” and the branch or bud above it is called a “scoop.” In modern times, during the process of grafting, it was discovered that some rootstocks can extremely reduce the size of the tree that has been grafted onto the “scout” and turn it into a “dwarf” in the fruit tree. This kind of rootstock is also known as “dwarf”. Anvil.“ The average fruit tree has a height of 5-8 meters, but the use of ”dwarf anvil" breeding
