The invention relates to a protected fruit tree, particularly relates to a protected grapevine cultivation method, and belongs to the technical field of fruit cultivation. In the method, through adopting a seedling raising technique, a quick gardening technique for green seedling cultivation in summer, a forced dormancy technique, a germination accelerating and pre-maturing technique and the like, a cultivated grapevine variety is strong in stress resistance, and not easy to have the phenomenon of flower and fruit drop in bad environments; the rooting capability is extremely strong, the survival rate of branches subjected to cuttage is more than 90%, and the rooting rate of pressed seedlings of a mother tree is 100%. A grape bunch is cone-shaped and extremely compact, the average bunch weight is 800g, and the maximum bunch weight is 2000g; a grape berry is oblong, bright purple and easy to color, and the average weight of grape berries subjected to fruit thinning is 10-12g, the maximum berry weight is 20g, and the grape berry does not fall and crack; the soluble solid content is 18-21%, and the acid content is about 0.4%; and the fruit flesh is crisp, has rich rose fragrance, and enable people to nearly fell no tart flavor, therefore, the fruit flesh is superior in quality.
