There is a close relationship between scaffolding, shaping and pruning of grapes. A certain frame needs a certain tree shape, and a certain tree shape needs a certain pruning method. The three must coordinate with each other to achieve good results. The purpose of grape shaping is to cultivate strong and long-lived plants, make them have tree shapes suitable for local climatic conditions and variety characteristics, facilitate farming, prevent and control pests and diseases, prune and harvest, and make full and effective use of light energy, so as to achieve high yield, stable yield and high quality.
