What effect does thinning out have on pear trees when planting them?

Comparing thinning out with heading back, when the pruning amount is the same, thinning out is more conducive to flower bud formation than heading back, because after thinning out fewer long shoots are produced and more medium and short shoots are produced, which is beneficial to the early accumulation of nutrients, and the branches are relatively sparse, which is beneficial to ventilation and light penetration, so it is conducive to flower bud formation. However, the number of flowers formed and the quality of flower buds are only more obviously improved when part of the long shoots are thinned out in appropriate amounts, the remaining long shoots are lightly headed back or not pruned, and the medium and short shoots are left unpruned; otherwise, it will not be conducive to flower bud formation.

Because thinning out increases the number of medium and short shoots and improves the ventilation and light penetration conditions, it is also conducive to improving fruit quality and increasing economic benefits.

To promote the growth of a local branch that is more than one year old, 1 or several branches can be thinned out from the upper part of that branch, which can promote the growth of this branch; to promote the sprouting of latent buds, or to make the growth of weak short branches become vigorous, branches can be thinned at the cut end to play the role of suppressing the front and promoting the back; to weaken the growth of a local branch, 1 or several branches can be thinned out from the lower part of this branch; to balance the growth of branch groups and prevent the phenomenon of strong front and weak back, the pruning method of thinning the front and promoting the back can be adopted to maintain the balanced growth of the branch group.

Properly thinning out slender weak branches and overly dense branches is conducive to flower bud formation on the retained branches. Thinning out branch groups that extend too long, are too dense or too weak can enhance the growth of the retained branch groups.
