1、 Pruning time

Pruning of Prunus triangularis is mostly in spring, when the plant begins to grow. Pruning is more conducive to recovery, and can also reduce nutrient consumption, which is helpful for plant flowering. If the pruning time is too late, it will delay its growth time and affect plant development

2、 Pruning method

1. Short cutting: if the growth of trigonometry plum is relatively slow, the development of new shoots can be stimulated by short cutting. This method is generally aimed at new branches. It is divided into light cutting and heavy cutting. About one third of the branches should be cut off for light cutting and half for heavy cutting. Usually, the cut should be close to the bud, so the stimulation effect is better. In addition, short cutting can also avoid the thickening of mother branches

2. Thinning: if the Prunus deltoides is too dense, the intersecting branches block the ventilation and light transmission, which is not conducive to the internal growth and the risk of causing diseases and pests, so thinning is needed. This method is mainly to cut off dense branches and overlapping branches, so that they can also be illuminated and have good air circulation. At the same time, weak branches should be removed to promote the growth of plants

3. Shrinking and cutting: if the old branches of triangle plum don't bloom much, we should consider shrinking and cutting. If the branch itself is not strong enough, it will not retain enough nutrients. Therefore, if the branch itself is weak, it will not retain enough nutrients, but it will not retain enough nutrients. In addition, the shrinkage shear can not be completed at one time, but should be carried out several times separately

3、 Curing after shearing

After pruning the plum, apply carbendazim to the wound to prevent it from infecting bacteria and causing it to get sick. At the same time, we should pay attention to fertilization and supplement nutrients for it, which is conducive to the growth of new plants
