Apples are specially trimmed

1. Over-the-top tree control when the tree is growing too high, branch growth is dominant, relatively causing the bud differentiation nutrition is insufficient, is not conducive to the formation of buds. For this kind of branch in the transformation, should be mainly to "slow" mainly, extend the length of the branch stay, generally cut in the weak buds, increase the angle of the main branch branch, remove the back of the branch group, more left side, lower branch group, the implementation of the backbone of the branch ring cutting and other measures to control the transport of nutrients, promote flowering. Theof the weak tree is pruned when the tree body is too weak, it can be re-cut on the basis of fertilizer water management to stimulate the growth. Extension branches should be cut in the middle full buds, with strong branches to take the lead, gradually raise the extension angle, less left behind the lower branch group, in order to prevent the weakening of the long-term trend of the branch, should be more left on the back and on both sides of the branch group, to promote growth. 3. The pruning of partial crown trees fruit trees with large branches and small branches when the crown grows, the solution is: first, dredging in the lower branches, dredging flowers in the upper part of the branches;4. Treatment of bare branches Some branches in apple trees for several years without cutting, often single-axis extension, rarely branching, forming a large section of bare, such branches into flowering performance is poor, due to limited nutritional area, fruit growth and development is poor. For this kind of branch in pruning, if there is room to deal with the implementation of ring cutting to stimulate bud germination, grow the required branches or timely retract, stimulate the branch,

good branch group, in order to expand the photolysal area. If there is no space, it should be immediately removed to improve the tree ventilation and light transmission conditions. . When pruning , the lower branch of the canopy can be extended with competitive branches, and the extension branch maintains a small angle extension to promote the growth of the lower branch. The middle and upper branches increase the extension angle, leaving the lower branches of the back as extension branches to balance the tree potential. 6. Treatment of strong branches under the upper and lower branches the lower branch extension, the back branch to take the lead, weaken the growth trend, the upper branch small corner extension, the back branch to take the lead, promote the growth of the boom. 7. Flower pruning Young trees and apple trees in the early stages of hanging fruit should take the lead in pruning with weak branches, in order to control the nutritional growth of the tree body, increase the accumulation of nutrients in the tree, promote flowering. Can also be auxiliary branching to implement ring cutting and other cut-off measures to promote flowers. 8. Measures to prevent the weakening of branches After the apple enters the fruiting period, due to a large number of results, the tree is very vulnerable to weakness, pruning should be more short-cut, retracted method. To strengthen nutrient growth and prevent tree weakness. It can also be used to increase the tree potential by keeping flowers in moderable amounts. 9. Treatment of cross branches The cross branches inside the tree adopt a retracted branch, long put a branch, when crossing between lines should be two lines of retractation, in order to set aside the work channel, improve ventilation and light transmission conditions. When the cross-branching between plants does not exceed 10%, it has little effect on the growth results, and more than 10% should be retracted.10. Treatment of parallel branches young trees and the results of the initial apple tree for parallel branches, should try to pull the use, in order to increase the amount of branches, into the fruiting period of the apple tree, in the absence of space, should be dredging a branch, put a branch, in order to improve the tree ventilation light conditions. Theof auxiliary branches the fruit tree of auxiliary branches should be differently pulled and pressed to promote flowers in order to increase the amount of tree results. Results should be immediately retracted to avoid rear baldness, cultured into a compact resulting branch. 12. Treatment of the internally loaded over-tight results branch group in line with the principle of dredging and mixing, remove the over-dense and disordered branches, retract too high and weak sagging branches, so that the branch distribution is uniform and compact, one or two years of auxiliary branching of the blocking light, can be dredging, excessive dredging set the gate before and after, concentrated nutrients, so that many years into flowers. For a single upright long branch, there is room to push flat, don't, pull, branch, ease the top advantage, no space to remove from the base. For the growth of moderate horizontal sagging branches, can be a small amount of "with live hat" concentrated nutrition. On the scissors at the scissors, there is time to leave a straight slope, no space can be all removed.
