苹果矮化苗繁殖方法有多种，我国常用矮化砧品种作中间砧。这种敏殖方法出困成苗率高，苗木定植后固地性好，但繁殖方法难，且时间长，一般需嫁接二次，苗木三年才能出圃。为缩短矮化苗木出圆年限，变3年为2年，我们从1992～1995年经过4年的试验，总结出一套行之有效的苗木快繁
Apple dwarf seedlings have a variety of breeding methods, dwarfing anvil species commonly used in our country as an intermediate anvil. This method of sensory out of sleepy into a high rate of seedlings, seedlings after planting solid, but difficult to reproduce, and a long time, the general need to graft second, seedlings three years to nursery. In order to shorten the growth period of dwarfing seedlings, change 3 years to 2 years, we from 1992 to 1995 after 4 years of experiment, summed up a set of effective seedlings fast propagation
