Young pear trees are trees that have been 5-6 years old, have not yet yielded results, or have just begun. This period of tree age is an important period for the formation of a crown. The main task of pruning is: According to the tree structure of the selected tree, selecting and cultivating the backbone branches, and appropriately cultivating the resulting branches, so that the young pear trees can enter the result period at the same time as they rapidly expand the crown.
The pear tree with trunk sparse layer is used for 1-2 years after the planting. After drying as required, the main branch of the first layer is selected and the second main branch is selected for the third year. After the selection of the main branch of the second floor, one main branch is selected each year until it is selected.
From the first year after the completion of the work, for the long branches issued each year, except for those selected as the backbone branches, the remaining branches shall be cut or not cut as little as possible.
After the first layer is selected, the branches that occur underneath each year should be trimmed and sparsely maintained so that there is sufficient room for the first and second lateral branches to be selected. The distance between the layers is large, and the auxiliary support can be properly selected. The first and second branches on the main branch of the first floor were selected when they were two or three years old, and the third and fourth side branches were selected when they were born in four or five years. For each of the selected lateral branches, the branches with more prosperous growth, angle, and orientation should also be selected as the prolongation branch and the length of the extension of the lateral extension branch, which can be the same as or slightly shorter than the length of the extension branch of the main branch. But don't grow longer than the main branch extension.
For the long shoots that occur every year, except for the use of the main branches and auxiliary branches, the remaining long branches should be used as far as possible to cultivate the result branches. The medium and short branches should be kept as much as possible. If the growth is too strong, it must be properly controlled; if the growth is weak, it can be slow-released to promote its flowering results.
Most varieties of pear trees have a low germination rate, although they have a high germination rate. Therefore, the branches of young pear trees are small. In order to rapidly expand the canopy and achieve early yields, we should try to stay as few as possible for branches other than the backbone branches; for long branches that do not affect the growth of the backbone branches, we must also put them slowly; for long branches that affect the growth of the backbone branches, we can appropriately shorten the branches. By suppressing the height of its top, it inhibits the growth of long branches.
In order to obtain the early production of pear trees, in addition to pruning, pruning measures such as less branches, more branches, light and short cuts are needed to promote the expansion of the crown, and some of the middle and short branches are formed, and appropriate cultivation measures should also be adopted to pass through the trees. The comprehensive management of the upper and lower trees aims to achieve early results and early high-yield production.
