Pruning fruit trees in autumn does not affect the flowering and fruiting of the next year. For example, autumn pruning of apple trees is very important for high and stable yield in the following year. Apple tree pruning in autumn mainly adopts technical measures such as pulling branches, thinning branches and light pruning.

(1) Pull the branches to slow down. Branching refers to pulling branches with inappropriate angles to the required angles, usually before the autumnal equinox. The angle of branch pulling generally requires that the main branch should be pulled to 70 ~80 degrees, and the auxiliary branch and temporary branch should be pulled to 90 ~ 100 degrees, depending on the variety, ground conditions and tree potential.

⑵ Sparse branches and transmit light. Dense branches in the sparse room, long branches on the back, upright branches, competitive branches and weak branches. In this period, it is not easy to peel when thinning branches and cutting mouths, which can avoid the phenomenon of excessive peeling caused by thinning branches in winter.

(3) Light cutting promotes flowers. Cutting the shoots lightly or wearing a hat at the blind joint of spring and autumn shoots can reduce nutrient consumption, facilitate nutrient accumulation and significantly promote flowering.
