Second, the pruning methods of pear trees are mainly shaping and shaping, and there are two main styles of pear trees, mainly evacuation layering and multi-branch natural modeling. The two tree types have their own advantages and disadvantages, depending on which advantage growers value more. But pests and diseases, weak branches and too dense branches should also be pruned.
1. Evacuation layered type
First, determine the backbone. Generally, the height of trunk from the ground should be around 1 m. Then, among the sprouting and sprouting branches at one meter, three strong lateral branches should be kept, and the three lateral branches should be staggered and not in the same direction. Then all the leaves of the sprouting branches on the trunk are removed, leaving three or four fruiting mother branches on the three lateral branches respectively, and all the other branches are thinned. Finally, select 5-7 fruiting branches on the fruiting mother branch and cut off the remaining weak branches. After the lateral branches, fruiting mother branches and fruiting mother branches are selected, they should be pitted to avoid unnecessary growth and accumulate nutrients to promote new branches.
2. Multi-branched natural form
Fix the stem half a meter on the trunk, but don't fix it too obviously. After fixing the stem, let it grow naturally, then choose all the strong branches to stay and cut off the rest. Form a number of main branches, leaving only strong mother branches on the branches, removing the weak ones on the mother branches, and naturally pruning them, but the remaining branches should also be topped. This kind of pruning can be shaped.
