The invention discloses a method for cuttage and seedling breeding of peach trees. The method comprises the following steps of preparation of a cutting slip, preparation of a seedling breeding bed, cuttage of a peach tree seedling, and care after cuttage; specifically, shearing the slope of a twig from a parent plant of peach tree as the cutting slip, putting the slope end of the cutting slip into a prepared disinfector water solution, soaking, fetching out, cleaning by sterile water, putting into a prepared rooting agent water solution, soaking, fetching out, and drying the slope of the cutting slip by ultraviolet rays, wherein a matrix of the seedling breeding bed is prepared from the following materials of pond mud, sands, earthworm dung, plant ash, human and animal excreta, seaweed fertilizer, carcass, and sugarcane residues; cutting the peach tree seedling, and caring. The method has the advantages that the seedling breeding period is obviously shortened, and the survival rate of the cutting slip of peach tree is obviously improved; the operation method is simple, the cost is low, the danger is avoided, the artificial operation is easy, and the pollution is avoided.
