Apple tree pruning video and 12 pruning methods

The planting network has sorted out 12 methods of apple tree pruning, which are listed in detail below for reference by the majority of netizens. Pruning method 1, such as apple tree potential growth is too prosperous, branch growth is dominant, not conducive to flower bud formation. When pruning, we should give priority to "slow", increase the branch angle of the main branch, remove the upper branch group, leave more side and lower branch group, prolong the branch length, and adopt ring cutting to the backbone branch to control the transport of nutrients and promote flower formation. Pruning method 2. If the growth of the apple tree is too weak, heavy pruning can be carried out on the basis of fertilizer and water management to stimulate the growth. The extended branches should be cut at the full buds in the middle, take the lead with strong branches, gradually raise the extension angle, leave less inferior branches, and more branches on the back and on both sides. Pruning method 3, such as apple tree one side branch is big, the other side branch is small, appear partial crown growth, one is thinning branches under the branch, sparse flowers on the upper part of the branchlet; second, pull the big branch angle, raise the branchlet angle; third, the big branch leaves more fruit, the branchlet leaves less fruit; fourth, the big branch direction should be less fertilizer, the twig direction more fertilizer, it is strictly forbidden to use the method of big cutting to transform the tree shape. Pruning method 4, some branches of apple trees are not cut year after year, often uniaxial extension, rarely branches, forming a large section of bald, this kind of branches have poor flowering performance, poor fruit growth and development; pruning, if there is room, it should be ring-cut to stimulate bud germination; or retract in time to stimulate branches and cultivate good branches. If there is no space, it should be removed immediately to improve the ventilation and light transmission conditions of the tree. Pruning method 5. For the upper and lower weak apple trees, the lower branches of the crown can be extended with competitive branches to maintain a small angle and promote the growth of the lower branches. The middle and upper branches increased the extension angle, and the lower branch was selected as the extension branch to balance the tree potential. Pruning method 6, for the weak and strong apple trees, the branches extend at large angles, the back branches take the lead, weakening the growth potential; the upper branches extend at small corners, and the upper branches take the lead to promote vigorous growth. Pruning method 7. For young apple trees and primary fruit trees, weak branches should take the lead in pruning to control the vegetative growth of trees, increase nutrient accumulation and promote flower formation. The measures of river closure such as ring cutting can also be carried out to promote flowers in the auxiliary branches. Pruning method 8. After the apple tree enters the full fruit period, due to a large number of fruit, the tree potential is very easy to weaken, pruning should be more truncated, retractive techniques should be used to strengthen vegetative growth and prevent tree weakness. The tree can also be strengthened by keeping an appropriate amount of flowers. Pruning method 9. The cross branches in the apple tree should retract one branch and put one branch long; when the rows cross, both rows should be retracted so as to set aside the working path and improve the ventilation and light transmission conditions. Pruning method 10, young apple trees and early fruiting apple trees should be pulled and used as far as possible to increase the number of branches; trees entering the full fruit stage, in the case of no space, open one branch, put one branch, in order to improve the ventilation and light transmission conditions of the tree. Pruning method 11. In the early stage of apple tree growth, pulling and pressing should be adopted to promote flowers and increase the amount of tree fruit. After the result, it should be retracted immediately to avoid the rear baldness. Pruning method 12. Apple trees need to remove overdense and disordered branches and retract overly high and weak drooping branches to make the distribution of branches uniform and compact. The annual or biennial auxiliary branches that block the light can be removed. For a single upright long branch, there is room for distinguishing, pulling and smoothing the branch. Moderate withering, apical dominance; no space to be thinned from the base. For the general growth of drooping branches, can be a small amount of "live cap" concentrated nutrition. For the sprouting bar at the cutting edge, if you have time to go straight and stay oblique, if you have no time, you can remove it all.
