Select a main vine in the first year of planting, and when it grows to 30 -40 cm high, leave 5-6 leaves for coring; According to this method, the extended branches are repeatedly cored; Secondary branches within the range of 10 cm from the base of the main vine should be smoothed in time, 3-5 robust secondary branches should be selected from the middle and upper parts, and 4-5 leaves should be left for repeated coring; The remaining secondary branches can be re-cored with 1 leaf -2 leaves.

Prune the grapes when they are taken off the shelf in winter, and cut off the main vine for about 1 m; As a result, the secondary branch of the mother branch was pruned by 2-3 short branches; Sparse the remaining secondary tips.

In the second year, 6-8 new shoots with fruit ears were selected and tied on a fan-shaped frame. Leave 6-8 leaves on the ear for coring; Leaves 1 leaves are repeatedly cored at the secondary tip -2 leaves.

2. Potted grapes in funnel frame

In the first year of planting, 3-4 new shoots are selected as main vines, which are vertically tied and evenly distributed on the frame surface, and the tips are picked at about 1 m. Can be used as the secondary branch of fruiting mother branch culture, leaving 4-5 leaves for repeated coring; Cut off the sub-tips that are too dense and weak.

Prune the grapes when they are taken off the shelves in winter. If the main vine is strong and mature, it can be kept long, but the total length is lower than the frame surface. Pruning the secondary branches on the main vine that can be used as bearing mother branches; Secondary branches that cannot be used as fruiting mother branches should be cut off. If the main vine is not strong enough and there are no secondary branches that can be used as fruiting mother branches, it should be appropriately cut short and the fruiting mother branches should be cultivated in the second year.

In the second year, if there are fruiting mother branches on the main vine, 5-8 leaves are left above the new shoot for coring, and 1-2 leaves are left on the secondary shoot for repeated coring. If there is no fruiting mother branch on the main vine, extend the new shoot to pick the core in time, and select the strong new shoot to leave 4-5 leaves for repeated core picking. Leaves 1 leaves are repeatedly cored at the secondary tip -2 leaves. The winter cutting method is the same as before.

In the spring of the third year, thin new shoots should be drained as soon as possible, and 10- 12 new shoots should be kept, and the rest are the same as before.
