The invention relates to a cultivation method capable of postponing the mature period of grape leading shoot fruits. The cultivation method is characterized by: removing fruiting parent branches which are immature or have the diameter smaller than 0.5 cm after entering the fruiting period at the time of leaf falling in winter, and not pruning the preserved fruiting parent branches in winter; spraying a growth inhibitor for the first to delay the growth of new tips after spring beginning when the winter buds of the fruiting parent branches germinate to generate 8-12 cm-long new tips; pruning the fruiting parent branches when the winter bud new tips at the top of the fruiting parent branches grow to about 20-25 cm length, and preserving 1-3 winter buds at the bottom part; and spraying the growth inhibitor for the second time to delay the growth of the net tips and the formation of inflorescence when the winter buds germinate and generate 2-3 leaves.
