Attention should be paid to Postharvest pruning of Peach trees

Peach tree itself has the characteristics of vigorous growth, strong branches, excessive branch growth and many branches. Most fruit growers do not pay attention to post-harvest pruning after picking peaches (especially early and mid-ripe varieties), resulting in increased excessive branches, closed crown, poor ventilation and light transmission, affecting flower bud differentiation, serious disease and insect occurrence, resulting in a decline in yield and quality in the second year, resulting in the phenomenon of "full flowering trees in spring, full branches in summer, fewer peaches hanging on branches".

After peach fruit harvest, strengthen soil and fertilizer management, timely control diseases and insect pests, strengthen pruning in growing season, control branches to grow long and excessive, promote the formation of full flower buds, control fruit position to move upward and outward, can play a multiplier effect.

The tree that bears fruit first, backbone branch angle is small, want to pull branch to open angle. The newly sprouted and growing branches grow to about 30 cm, and then they are picked. Thinning out over-dense branches, thin branches, drooping branches, injurious branches and upright branches with no use value in the upper part. For the weak old branch group, thin branches should be cut properly to reduce nutrient consumption and improve the illumination and ventilation of crown. Retract overlapping branches, cross branches and some senescent fruiting branch groups. Truncate the fruiting branch at the top of the fruiting branch, and reserve the branch near the base as much as possible. Thinning off the top strong branches, and then twisting branches at the base, control growth, promote its fruit. For the erect vigorous branches which have the value of reforming the inner bore, select the basal branches, cut short or twist the branches at the weaker auxiliary shoots, slow down the growth and promote the fruit. Competitive branches can be sheared or twisted to control growth and form fruiting branch groups. For peach trees with few branches in the crown, the angle of main branches should be opened as far as possible, nearly horizontal, increase the number of branches in the crown, and it can also be carved in a ring to promote the germination of new branches. Before defoliation, the new shoots should be picked or twisted to promote them to become branch groups and increase the fruiting positions.
