Short cutting refers to cutting off a part of branches, and retraction refers to short cutting on perennial branches. Both pruning methods promote local growth and multi-branching. Different degrees of light and heavy pruning have different reactions. In order to improve its angle, it can generally be shrunk to the branches where the perennial branches diverge.

When cutting short annual branches, we should choose cutting buds and correct cutting methods according to the position of branches.

(2) refinement and slow release

The method of cutting branches from the base is called thinning, which is also called thinning. When the branches of fruit trees are too dense, they should be thinned. Thereby improving wind and light conditions and promoting flower bud formation. Thinning and cutting have completely different effects.

Slow release is also a method of pruning, that is, the buds on the branches germinate freely without pruning. Slow release can not only alleviate the growth potential, but also be beneficial to the bearing of axillary flowers. After the branches are slowly put into the buds, they can be retracted and trimmed. This pruning method is often used for young trees and lush trees. Where there are many branches, short pruning method should be adopted; The branches are too dense to open; And the branches that grow too vigorously should be released slowly. Only reasonable pruning can make fruit trees grow and bear fruit correctly and achieve the requirements of early, stable and high quality.

(3) Nucleation and sharpening

Core picking is to remove the tender growth point at the top of the new branch, and tip cutting is to cut the longer new branch. Its function can not only inhibit the growth of branches, save nutrients for flowering and fruit setting, avoid unnecessary waste and improve fruit setting rate, but also promote the formation of flower buds and flowering and fruit setting on other fruit branches. Tapping can also promote root growth, lateral bud germination and secondary branch growth. This method can accelerate the formation of branches, increase the number of branches in rapid prototyping, and thus improve the ability to carry results.

(4) Bud wiping and shoot thinning

Wipe off the bud by hand or cut it off with scissors, which is called wiping or removing the bud. Thinning refers to thinning too dense new branches when new branches begin to grow rapidly. The effect of these two pruning measures is to save nutrients, thus promoting the growth of new shoots and making them flourish; Removing lateral buds and branches and improving illumination are beneficial to the enrichment of branches, flower bud differentiation and fruit quality improvement. Removing useless buds and branches as early as possible can reduce the big wound and a lot of nutrient waste caused by removing big branches in the later stage.

(5) Branch pulling

Pulling branches means pulling apart the main trunk branches at a small angle. This method can slow down the leafy branches. Spring when sap begins to flow is suitable for branching. Pull the branches down with rope or iron wire, and pad the parts close to the branches with soft objects such as rubber or cloth to prevent skin damage.
