1、 Pruning time

Pruning time of pruning is mainly after flowering and before germination

2、 Trim type

1. Cutting: cutting is to cut a part of the branch. After cutting, new branches will be sent from the branch below the cutting mouth, and two to four new branches can be sent from the bottom after cutting a branch. The branches can be shortened and densified by cutting

2. Thinning: thinning is to completely cut off the branches from the base of the branches. Through thinning, the crown can be loosened, the permeability can be improved, and the amount of branches and leaves will be reduced. Only by combining the two can the pruning of trigonometry plum be better

3、 Specific pruning method

1. The cutting method can be divided into heavy short cut, medium short cut and light short cut according to the weight. The so-called heavy short cut is to cut off a large part of the branches, leave a third to a quarter of the part, and completely cut off the others. This is mainly carried out in the dormant period of fallen leaves, which will affect the number and direction of branches after re germination next year, which is very helpful for plant shape adjustment. About half of the branches will be cut off in the medium short section, and about one-third to one-quarter of the branches will be cut off in the light short section, and most of them will be retained. When pruning, whether to use medium short section, heavy short section or light short section depends on the specific branch direction and tree shape

2. The method of thinning can be carried out in the dormancy period or in the growth period. It is mainly to cut off the small, weak and dense branches inside the crown to prevent the trunk from being too bloated and affecting the ventilation and light transmission, which will improve the occurrence of diseases and pests

4、 Precautions

The pruning of trigonometry plum is comprehensively used in these methods. The branches growing in shape should be balanced to avoid some branches growing too strong. At the same time, some branches grow too thin and weak, so that the development of this branch is more balanced and the orientation is more reasonable. For the new buds and new branches produced during pruning, try to leave the external branches and part branches, so that after several years of pruning, it will become very beautiful
