Apple tree pruning is a key part of improving apple production. Only after the pruning work is done, the quality and yield of apples can be quickly improved, and reasonable pruning can retain the supply of nutrients for high-quality fruits. High-yield pruning technology now!
1. Short cut
Short cut is to cut a part of the annual branch, and is divided into four types, namely light short cut, medium short cut, heavy short cut, and extremely heavy short cut. It is used to promote the growth of branches, expand the crown of the tree, and weaken the cultivation of branch vigor. The twig group has a very good effect. The short cut can shorten the branch axis and shorten the distance of nutrient transport, which is conducive to promoting growth and rejuvenation. Enhance top advantage.
2. Shrink shear
Shrinkage shears are for part of the multi-year branch. Shrinkage shears are generally thinned first or short shears. When the growth is weak, they are retracted.
Shrinkage can change the growth direction of branches, which is good for ventilation and light transmission, weakening the mother branch, and has a good effect on the regeneration of weak branches, controlling or weakening auxiliary branches.
3. Thinning
Remove branches from the base, reduce branches, and improve the light inside the canopy. It is useful for improving the ability to bear fruit. It is generally used to remove competing branches and cross branches. However, thinning can not be blind. If the flower buds, fruiting branches, or ineffective Branches, on the contrary, will strengthen the overall and mother branches. Generally used to control the growth of upper branches and enhance the growth of lower branches.
4. Long release
Do not prun the annual branches, keep the top buds of the branches, and let the top buds shoot. Generally used in young trees, it is helpful to relax the tree vigor and promote the differentiation of flower buds. But keep in mind that competitive branches and long-standing branches cannot be allowed to grow forever. Horizontal branches and oblique branches can grow long.
5. Quzhi
Artificially changing the growth direction of branches, making full use of space to promote tree results, can change the top advantage, reduce branch vigor, improve germination, reduce branching force, increase medium to short to the number, which is conducive to flowering, and can also make full use of space to make The branches are evenly distributed and well lit.
6. Wipe buds
Wiping buds is to wipe out weak buds and multiple buds, which is very helpful for cultivating strong buds, saving nutrients, improving light conditions, and improving the quality of retained shoots.
7. Topping
Topping is to remove the young tip. It can promote the germination and secondary growth of lateral buds and increase the amount of branches. It is meaningful for early results and can significantly increase the fruit setting rate.
The above is the introduction of high-yield pruning techniques for apple trees. If a farmer friend wants to grow high-yield apples, he must master scientific pruning techniques. I hope the above will help everyone.
