1, spring pruning
Pruning in spring is the basic point in cherry tree pruning map, and pruning in bud is the key to plant growth. When budding, try not to over-prune. Generally, pruning is mainly based on pinching, which is mainly carried out when the trunk length of the plant is 32 ~ 40 cm, and pruning should be done sooner rather than later.
2, young tree pruning
The pruning of young trees is mainly based on heavy pruning, that is, combing the branches that are growing too fast. Generally, the angle of the trunk should be kept at about 60 degrees, and the opening angle of the lateral branches should be kept at about 70 degrees. Draw the main branch and branch into a straight line, preferably not in an arch shape, and then carry out bud carving treatment on the main branch.
3. Pruning at the first fruit stage is mainly based on shaping at the first fruit stage. All the dense main branches and disorderly branches that affect the appearance should be cut off, usually from bottom to top, so that the main branches and branches do not affect each other, and then the fine side branches should be cut short to promote the flowering and fruiting of the plants.
4. Pruning at full fruit stage
In the full fruit stage, it is mainly to increase the ventilation and light transmission of the crown width, which is beneficial to the expansion and quantity of fruits. It can cut off the vertical branches and overlapping branches that affect the growth in the crown, appropriately cut off some cross branches and leaves that affect the beauty, and erase the buds at the crown top to avoid consuming nutrition.
