In actual production, because sweet cherries are not pruned or cannot be pruned according to the growth and development rules of sweet cherries, it often results in disordered tree shape, unclear structure, uneven branch growth, excessive growth, and premature aging of weak ones. Or the crown of the tree is too tall, but the fruiting parts are only on the periphery. Such trees often have too many thick branches and too small angles, making it difficult to have a high and stable yield.

The pruning and transformation of unreasonable tree shapes is mainly carried out after the fruit is harvested. The most important task is branch thinning. Based on the general principle of spindle-shaped uniaxial extension, large branches with reasonable positions are selected as the backbone, and overly dense and upright branches are thinned out or compressed into small and medium-sized branches. If the central stem is too strong, it can be dropped. If there are many branches on it, some large branches can be thinned out and modified according to the modified spindle principle. Then pull the selected large branches to the level as much as possible. Those that cannot be pulled into place at one time can be pulled into place within 2 to 3 years, or they can be pulled down by "triple sawing", splitting the base of the branches and adding wedges, etc., but these are often caused by excessive wounds. Poor healing, even gumming and dead branches. Appropriately thin out the small branches that are too dense at the tips of the large branches, and retract the long, thin and weak branches. Adjust the branches that are too dense in mid-to-late August.

In the spring of the second year, adjustments will be made according to the shaping requirements. The strong and vigorous branches produced in the first year will be flattened and buds will be carved to promote flowers. After that, regular summer pruning will be carried out, and a considerable yield will be achieved by the third year.
