Arm pruning
2. Cluster and cultivate three main vines, with several new fruiting branches on the main vines. The main vines and new fruiting branches are short, compact and simple in shape, suitable for small pots. Leave 8 ~ 10 cm short section on the trunk, and choose to leave 3 new shoots after germination to cultivate the main vine. When 9 ~ 12 leaves are unfolded, 7 ~ 8 leaves are left for coring, and 2 ~ 3 leaves are left for coring on the auxiliary branches. When pruning in winter, 5 ~ 6 buds are left for short planting, which can cultivate new buds sprouting from the lower part of perennial vines and prepare for pruning and regeneration.
Cluster pruning
3. Spiral, cultivate a main vine and let it spiral upwards. Leave 1 new shoots on the main vine, pick the core when it grows to 50 cm, and leave 2 ~ 3 leaves on the secondary shoots to pick the core. When cutting in winter, leave 40 ~ 45 cm for cutting, so that it spirals upward around the triangular bracket in the basin, and leave 3 ~ 4 new fruiting branches in the next spring, which are evenly distributed around the bracket. When cutting in winter, leave 30 cm of top bearing mother vines, and trim the rest with short branches. Leave 6 ~ 8 new fruiting branches in the whole plant, and don't leave too many branches. When the lower branches are weak, spare branches should be reserved for regeneration.
Spiral pruning
4. Fan-shaped, the main vine is upright, and there are 3 ~ 5 fruiting branches on the ground, which are distributed on both sides of the main vine. The trunk is 8 ~ 10 cm high, and the top 1 new shoot is selected, and 5 leaves are reserved for coring to promote secondary branches, and 1 ~ 2 leaves are reserved for coring. At the same time, the main shoot and the secondary shoot are smoothed, forcing the winter buds to germinate, leaving 5 ~ 6 leaves for the second winter bud branch to pick the core. The secondary tip of the coring port is still erased, and its lower secondary tip remains 1 ~ 2 leaves for coring. This repeated treatment can thicken the main vine and promote the differentiation of flower buds. When cutting in winter, 7 ~ 8 buds are left on the main branch and the secondary branches are thinned out. In the spring of the following year, 3 ~ 4 new shoots were left, and the top secondary branches were still erased by coring when 5 ~ 6 leaves were left. When pruning in winter, leave 6 ~ 7 buds short planted on the top fruiting mother branch, and prune the rest with short tips. By the third year, the whole plant can have more than 8 fruiting branches. In the future, the plant height will be controlled within 1.5m, and there will be 10 ~ 12 fruiting branches.
Sector pruning
5. Hanging hair shape: cultivate a main vine, with 3-4 fruiting mother branches evenly arranged around it, and sprout 6-8 new fruiting branches in the spring of the next year, so that they naturally hang down into a hanging hair shape. Cut the trunk to 10 cm, leaving only 1 new shoots in spring, smoothing the rest, removing the core when it grows to 4-5 cm, leaving 5-9 leaves for three adjacent sub-shoots under the core removal opening, and 1 ~ 2 leaves for the rest sub-shoots. In winter, 4 ~ 5 buds are left in the upper three auxiliary branches for short cutting, and the rest are thinned. In the spring of the following year, each of the three fruiting mother branches grew two new fruiting branches, which naturally drooped under the support of the scaffold.

Hairy pruning
6. Disc cultivation: 65,438+0 main vines are cut off according to the height of the shelf surface, and only the top 65,438+0 new shoots are tied on the disc shelf surface in the next spring. When cutting in winter, the new buds are coiled in the middle of the tray surface, and the redundant parts are cut off. The late shoots are pruned with short branches, and a new shoot is left after germination in spring, so that it is evenly distributed on the shelf surface.
Disc pruning
7. Step-shaped, cultivate a main vine, and the results show that the branches spread horizontally alternately on both sides, such as steps, drooping ears and beautiful shape. (1) Fix the main vine type, select a robust main vine, cut it to a certain height according to the size of the basin, and stretch it laterally to both sides after making. When cutting in winter, leave 1 ~ 2 buds chopped, and then cultivate here the next year. (2) The main vine is newer, with a certain height of fruiting mother vine in the first year, and 1 new branch is selected from the base after germination in the second year, and the ear is picked as fruiting mother vine in the third year. The original fruiting vine grows behind the upper part and is tied left and right. When pruning in winter, the fruiting vines begin to taper from the base. After that, a preparatory vine is cultivated in the base every year, and the fruit is thinned after fruiting.
Step pruning
8. Prune grapes with few main vines, plant them in tanks or barrels, and prune them in scaffolding, with 1 ~ 2 main vines per plant. When planting, leave 3 ~ 4 buds for short cutting and 1 ~ 2 buds for new shoots. Cut 6 ~ 8 buds in winter, choose 3 ~ 4 robust new shoots for each main vine in the second year, and smooth all the rest. In winter, about 12 buds are left in the new shoots of the main vine for cutting and planting, and the rest are left with 2 ~ 3 buds for short cutting. After that, about 8 buds are reserved for long-branch cutting of main vines, and the rest 2 ~ 3 buds are reserved for short-branch cutting, so as to achieve double vines and double innovation. In summer, when the elongation branches are 12 ~ 14 leaves, the remaining new shoots are 8 ~ 9 leaves, the new shoots are 5 ~ 6 leaves, and the lower secondary branches are 1 ~ 2 leaves.
Trim with less main vines and scaffolding.
9. Prune with multiple main vines. When the scaffolding on the roof and platform is large and the tree is strong, 3 ~ 4 main vines are left for each plant, and several bearing branches are evenly planted on the main vines. After planting, 3 ~ 5 buds are cut short, 2 ~ 3 robust new shoots are cultivated after germination in spring, 45 ~ 50 cm short shoots are kept in winter, and 1 ~ 2 robust new shoots are cultivated in the next year to form the main vine. 2-4 fruiting branches are evenly distributed on each main vine.
