Apple special trim 12 strokes

Apple special pruning twelve tricks 1. Over Wang tree control? When the tree vigor grows too busy, the branch growth dominates, relatively caused flower bud differentiation nutritional deficiency, is not conducive to flower bud formation. For such branches in the transformation, should be mainly "slow" mainly to extend the long stay branches, generally cut at the weak shoots, increase the branch angle of the main branch, remove the back of the branch group, more stay side, lower branch group, implementation Such measures as circumcision of circumcision, control of nutrient delivery, and promotion of flowering. 2. Promoting pruning of weak trees? When trees grow too weak, they can be stimulated by heavy shear on the basis of fertilizer and water management. Extension branches should be cut in the middle full of buds, with strong branches to take the lead, and gradually increase the length of the extension, leaving less branches to avoid weakening the growth of the branches, should stay on the back and both sides of the branches to promote growth. ? 3. Pruning of the crown tree? The fruit tree branches on one side, a small branch appears when the crown growth, the solution: First, the branches in the lower branches, thin flowers in the upper branch; the second is to pull a large branch angle, raising the branchlets Angle; Third, large branches and more fruit, twigs and less fruit; Fourth, the direction of large branches to be less fertilized, fertilization in the direction of the twigs, is strictly prohibited to use the big cut method to transform the tree. 4. Treatment of Bare Branches Some branches of apple trees do not cut for several years in a row, often uniaxially extending, rarely branching, forming large sections of baldness, poor flowering performance of such branches, due to limited nutritional area, poor fruit growth and development . For pruning of such shoots, if there is space for the implementation of the ring cut to stimulate bud germination, grow the desired shoots or timely retraction, stimulate the hair sticks, cultivate good branches to expand the photosynthetic area. If there is no space, it should be removed immediately to improve the ventilation and light conditions of the tree. 5. Treatment of strong and weak weak trees When pruning, the lower branches of the crown can be extended with competitive branches, extending branches to maintain a small angle, and promoting the growth of the lower branches. The middle and upper branches increase the angle of extension, and the remaining branches are selected as extension branches to balance the tree potential. 6. Treatment of the weak branch and strong branch: The lower branch has a large horn extension, and the rear branch leads and weakens the growth potential. The upper branch extends at a small angle, and the back branch takes the lead and promotes vigorous growth. 7. To promote flower pruning? Saplings and fruiting early apple trees, when trimming should be led by weak branches to control the vegetative growth of the tree, increase tree nutrient accumulation and promote flowering. It is also possible to assist in the adoption of circumcision and other closure measures to promote flowering. 8. Measures to prevent weakening of the branch? After the apple enters the full fruit period, due to a large number of results, the tree vigor can easily weaken, and pruning should use short cuts and retraction methods. To strengthen vegetative growth and prevent tree vigor. It is also possible to increase tree vigor by appropriate amount of flowering. 9. Treatment of cross-branches Cross-branches are used in the tree to retract one branch, and one long-term branch. When both cross-rows intersect, both rows should be retracted so as to leave the work path and improve the ventilation and light transmission conditions. When the crossbranch does not exceed 10%, the effect on growth results is not significant, and more than 10% should be retracted. 10. Treatment of parallel branches? Saplings and early fruit trees should be used as far as possible for parallel branches, in order to increase the amount of tree branches and enter the apple tree in full fruit period. If there is no space, it should be sparse. Put a branch to improve the ventilation and light conditions of the tree. 11. Auxiliary branch treatment? Auxiliary branches of fruit trees in the early growth period, should take the difference between pull and pressure to promote flowers, in order to increase the amount of tree results. After the results should be immediately retracted to avoid posterior baldness and cultivated into a compact group of results. 12. To deal with the results of the internal condylar result of the constitution of the constitution, to eliminate the dense and disturbed branches, retract the exorbitant and weak pendulous branches so that the branches are distributed evenly and compactly. The first and second year of light supplementing the branches can be eliminated. After the overcrowding is set and the barriers are suppressed, the nutrients are concentrated to make it become a flower for many years. For a single upright leggy branch, there is room to push down flat, do not pull, lychee, and ease the top edge. No space can be removed from the base. For drooping branches with moderate growth levels, a small amount of "bringing caps" can concentrate nutrition. For scallops at the mouth of the slash, go straight and stay oblique.
