It is carried out from December after falling leaves to the second year before sprouting.
First of all, according to the growth characteristics of pear trees with obvious top advantage, strong germination ability and weak branching ability, which are mainly short fruiting branches, the big and weak trees should be pruned heavily, while the small and prosperous trees are suitable for light or direct cutting. Second, look at tree pruning, for different types of branches to take different pruning methods.
With short section as the main part, and with proper amount of overhaul shear, the angle of the main branch can be opened by means of bracing, pulling and hanging.
Keep the strong branches, cut off the weak ones and renew them in time. It is necessary to specially prune the branches with too many flower buds and short and weak growth of new shoots, properly cut and thinly cut the dense branches and weak branches, and in the case of general weakness of branch group, it is necessary to carry out more shrinkage and regeneration.
There is extra space in the crown, especially for the gap between the backbone branches, we should try to keep more planting branches, adopt the method of annual branch, first year not cutting, second year flower bud short cutting, also can carry on the retraction after the result. If it has an effect on the growth of the bone trunk, we can take measures such as increasing the angle, removing the straight and oblique, removing the strong and weak, and releasing the result slowly.
The fruit platform of pear trees often has about 1-3 sub shoots, which can be kept as short as one or as sparse as one. The pruning of short fruit branches needs to determine how many short fruit branches should be reserved according to the load of the whole plant. If the tree is weak, the weak branches and weak buds should be spared. In addition, the leaf clump branch is suitable to stay strong and weak, remove dead branches, dense branches, weak branches, disease and insect branches, etc.
