Pruning technology and tree shape of cherry tree

Truncation and core removal, cutting off a part of cherry branches, reducing the top advantage of branches, and light and short cutting horizontal branches and oblique branches; Dewatering treatment: under the condition of good growth, the dense branches, cross branches and overlapping branches of cherry are mainly drained; Shrinking and pruning, reducing the number of branchlets on big branches and removing unnecessary sprouting strips; Prune slowly, the strong branches can be shortened appropriately, and the branches with medium growth can be pruned in the following year.

1, truncation and coring

Light chopping is to cut off a part of the cherry branch. Light and short cuttings have the function of reducing the top advantage of branches, which is beneficial to improve the germination rate, increase the amount of short branches and produce more bouquets of fruit branches. Therefore, light pruning and short pruning of horizontal branches and oblique branches on young trees can increase the amount of short branches and facilitate early fruiting.

2. Refinement treatment

Under the condition of good growth, the dense branches, cross branches and overlapping branches of cherry can be mainly drained, which can reduce nutrient loss and improve lighting conditions. Pruning and thinning branches should not be too much during dormancy, and the tree shape should be adjusted after fruit picking. Moreover, in order to protect the wound, lead oil can be used to wipe the wound to avoid pus or cracking.

Step 3 shrink and trim

For cherry trees in abundant years, in order to improve sunlight exposure, reduce the number of branchlets on big branches, concentrate nutrients and water supply to left branches, shrink fruiting branches for regeneration and rejuvenation, remove unnecessary sprouting branches and promote the growth of updated branches.

4. Slow-release pruning

Strong branches, especially straight and strong branches, should not be delayed. Young trees and early-bearing trees of sweet cherry can delay some flat and oblique branches with moderate growth potential to promote more bouquets to bear fruit and bear fruit ahead of schedule.
