What are the advantages of pulling branches in orchard in spring, and how to pull branches correctly?

Branching is a basic method in fruit tree pruning, such as cutting short, retracting, thinning branches, slowly releasing, pinching branches, twisting branches, taking branches, pulling branches, carving buds, girdling and so on. These are the basic methods of fruit tree pruning.

There are many ways to pull branches of fruit trees, such as bending branches, turning branches, branching, pressing branches, supporting and so on. , all belong to the category of pulling branches. The ultimate goal of branch pulling is to make the branch angle open to the required angle, which is to weaken the top advantage of branches, ease the tree potential, improve the germination ability, make the distribution of nutrients and hormones in the tree balanced, and be conducive to the formation of flower buds. At the same time, pulling branches can also increase the angle of branches, which can improve the lighting conditions and increase the photosynthesis of leaves. Why do fruit trees pull branches in spring? Because fruit trees gradually enter the budding stage in spring, the branches of fruit trees are soft, tough and not easy to break. If the branches are pulled before the fruit trees germinate, the branches are dry and brittle, not easy to bend and break, and the thick branches are easy to split. If the branches are pulled in the late growth stage of fruit trees, gummosis may occur in the damaged parts, and freezing injury is easy to occur during wintering.

Branching is mainly used to pull up upright branches, branches with small angles, branches with vigorous growth or drooping main branches or side branches. The main means of pulling branches are rope pulling, angle opener, wooden stick support, and falling of stones or containers. There are many big cherries cultivated here, and the branches of big cherries will not open at a certain angle and will not bloom easily, so they should be pulled out. Based on the principle of "thinning, oblique crossing, thinning, moderate, strong, slow release, thinning weak branches, short cutting and increasing the angle of main branches", the big cherry was pruned.

Before pulling the branches, cherry should soften the branches before pulling them to prevent them from breaking. Thick branches with small angle are easy to crack when pulling branches, so when pulling thick branches with small angle, 3-5 saws should be connected to the back of the base, and 7- 10 or more saws can be connected to thick branches with too small angle, and the wound can reach1/3–12 of xylem, and then pull again. When pulling, the wound should be When pulling out the annual branches of Prunus cerasus/KLOC-0, it is necessary to combine measures such as bud carving and bud wiping, and take more medium and short branches to balance the growth before and after. If you only pull out the branches without carving the buds, wiping the back buds and removing the top buds, it will lead to more upright branches and less inclined middle and short branches.
