The invention relates to a high-quality fruit-tree sapling cultivating method. The high-quality fruit-tree sapling cultivating method includes steps of selecting a resistant stock of a fruit tree, accelerating germination of laminated stock seeds and sowing the seeds into a nutrition bowl or a hole plate, transplanting to the land after four to five months, picking buds when the stock grows into 50-120 cm, accelerating branches, properly grafting the branches to required varieties when the branches grown into the thickness suitable for grafting, lifting the saplings for the second time and then planting the saplings with cut main roots, ridging and planting the saplings with the cut roots in cultivating belts, applying base fertilizer, reinforcing management, accelerating before controlling by microbial nutrition fertilizer, and selling the nursery stock. By the high-quality fruit-tree sapling cultivating method, high-stress-resistance high-quality fruit saplings with strong fiber roots and strong and robust ground tissues and without principal roots can be cultivated.
