How to do a good job of winter pear tree pruning

Cultivate tree skeletons and speed up branch expansion. Each year, the extension branch is selected to carry out mid-cutting, promote long branches and accelerate crown expansion.

Take various measures to open the branching angle. Such as pulling branches, branching branches, falling branches, election buds, etc., because "high yield is not high yield, opening angle is the key."

Balance the tree trend and straighten out the master and slave. If the tree potential is not balanced, the strong branches will benefit, the weak branches will be weak, and the nutrients, growth, yield, and illumination will all have problems. When pruning, the center dry is stronger than the main branch, the main branch is stronger than the side branch, and the main branch is stronger than the auxiliary branch. The use of slow pruning for the strong branches of strong trees, that is to say, more cuts and less cuts, only sparse blocking, strong straight branches, leaving flat oblique branches, open angles with weak branches and weak buds to replace the head. In particular, we must eliminate the perennial branches that are the most prosperous and most prosperous. For the weak and weak branches, the method of pruning and trimming is adopted, that is, multiple cuts, less throws, heavy shrinks, light sparse leaves, weak leaves, and strong branches are preserved, the angles are raised, the elevation angle is raised, the polarity is used, and the buds are replaced with strong branches. .

Improve crown light. In the fruit period of pears, the situation of “lighting up, outsourcing, and grabbing before” is most likely to occur. Therefore, the large branches and strong branches of the center must be removed in time, and finally, the joy of falling over the head should be inhibited. . Sparse the outside of the dense mass strip, break the encirclement, and evacuation "outside." Remove the perennial branch of the main branch from the front of the main branch, pull out the “tree on the tree”, and open the front light path, so that the light from top to bottom and inside and outside are even and three-dimensional.

Younger groups are often maintained. Branches that have weakened their results after years of rejection should be gradually retracted, making them shorter and stronger and without space. For the branches and branches that have been pressed under the branches earlier, the result tasks have been completed, and they should be removed promptly. For the large branch groups with many years of results, especially the large groups on the back, they must be transformed into the middle group and returned to the retracted position; for the Mizhi group, In particular, the group and the weak group should be appropriately sparse; for branches or short fruit branch groups that have been away from the branch for many years, they should stay far and stay weak, stay strong and close to the branch axis, and achieve compact results.
