The invention relates to a propagation method of apple seedlings, which is characterized by including the steps: firstly, selecting rootstocks and scions; secondly, storing the rootstocks and the scions; thirdly, performing pre-grafting treatment; fourthly, performing scion grafting; fifthly, performing cuttage on a field; and sixthly, obtaining seedlings. The propagation method has the advantages that firstly, scion grafting is used instead of single budding, so that growth vigor of seedlings subjected to scion grafting is evidently better than that of the seedlings subjected to single budding; secondly, seedling raising time is shortened, production cost is lowered, and factory large-scale raising of seedlings in batch is achieved; thirdly, inter-stock seedlings are propagated with rootstock seeds instead of vegetative propagation, seedling propagation is all subjected to vegetative propagation, and accordingly, uniform sizes of trees in terms of production and cultivation are guaranteed; and the seedling raising time is shortened, and accordingly the speed of applying common apple seedlings and inter-stock nutrimental root seedlings is increased in China.
