What is the shape of the head-shaped pruning of the vine?
The basic tree structure of vine head pruning is that the plant has an upright and stout trunk with a height of 0.8 ~ 1.2 m, and the top directly bears bearing branches and bearing mother vines. Results The height of the mother vine from the ground should be1~1.5m. This tree is called head pruning because its branches are concentrated and head-shaped.

Branch culture can be short pruning or medium-long pruning. The advantage of this shape is that the tree body is simple in structure and easy to prune. After the upright trunk is thick and hard, there is no need for pillars or only a single wire fence frame to bind the bearing vines, so that the new shoots naturally droop without binding, saving the frame material, labor and pipe, and not strict with fertilizer and water requirements. The disadvantage is that the amount of pruning in the early stage of plastic surgery is large and the result is late. In the middle and late stage, there are few branches and vines, so the space can not be fully utilized and the yield per unit area is low. The trunk is thick and hard, so it is not convenient to bury it in the cold. It is only suitable for producing and cultivating cold-resistant varieties in cold-resistant areas without burying soil. When green ornamental grapes are cultivated in courtyards and gardens in cold areas in winter, special cold-proof measures should be added during wintering.
