Grapes have winter buds and summer buds. Winter buds are composed of multiple buds (one main bud with multiple pairs). The main bud germinates in the following spring, and/kloc-0 can branch 3-6 times a year. Both winter buds and summer buds are mixed buds, and inflorescences appear behind the third to sixth leaves of the main branch and on the second to third nodes of the secondary branch. When the inflorescence does not appear on the branch, it is a developing branch.

After the grape seedlings are put into the pot, with the growth of the plants, it is necessary to set a bracket in the pot and shape the plants according to the shape of the bracket. Potted grapes can be shaped into a variety of tree shapes, such as funnel shape, hanging shape, fan shape, step shape, single arm shape, double arm shape, spiral shape, spherical shape and so on. The basic methods of plastic surgery mainly include:

1, in the same year of trunk shaping, 1 main vine was cultivated, and all other new buds were pulled out soon after germination. When the main vine grows to 8 ~ 10 leaves, remove the top to promote the growth of axillary buds. For the secondary branches that grow in summer, except the topmost 1 branch that grows upward instead of the main branch that has been cored, all other secondary branches have 2 ~ 3 leaves that need to be cored.

2. The cluster shaping method can leave 4-5 main vines in the same year, and every main vine leaves 1 secondary branch every 30-40 cm. When it grows to 5-6 leaves, the top is removed and the core is picked, and the main vine grows to 0. 8 ~ 1 m should also be cored.

3. Choose 2-4 new vines with 8-10 cuttings per vine, on the plants with growth of 1 ~ 2 years. Pruning in the second and third years, and selecting 2-3 strong vines as side vines on each main vine. Leave 6 ~ 8 buds on each side of the vine for pruning. Usually when it grows to 3 ~ 4 years, the main vines and side vines can be covered with the shelf surface.
