The invention discloses a method for breeding seedlings of grapes by using containers and belongs to the field of fruit tree seedling raising. The method comprises the following steps of: (1) scissoring annual grape branches in winter to conserve in winter; (2) taking out the branches in late February of the next year, cutting the branches into sections of 18 to 20 cm, retaining stalks of 2 to 3 buds, and inserting into containers by cuttage, wherein nutritional soil comprises a mixture of reed residue matrix and garden soil, or a mixture of rich chaff dust and garden soil, or a mixture of the reed residue matrix, the rich chaff dust and the garden soil; and (3) inserting bamboo poles with the length of 1m into the containers to fix young sprouts when nursery stocks have 7 to 8 leaves, and pinching when the young sprouts are 80 cm. The method is not limited by season, so the defects in seedling in big lands are effectively overcome, root systems are formed in the containers and have good and complete root balls, roots are not damaged when seedlings are lifted, the seedlings are not required to be trimmed before planting, one-step forming is realized, time and labor are saved, survival rate is high after transplantation, the slow seedling stage does not exist, growth quantity is large in the initial stage, flower bud differentiation is realized in advance, high yield in early stage is realized, and quality of the nursery stocks is high.
