Several misunderstandings of the latest apple tree pruning

Apple trees are widely distributed in China, and they are planted in many places. In the process of planting apple trees, orchard management is very important. And the pruning work is also indispensable, although many people know that it is necessary to trim. But the pruning method is wrong, there are many misunderstandings, resulting in poor results. So the editor below brings you several major misunderstandings about apple tree pruning, let's have a look!

1. Angle discomfort

When pruning again, many friends will only pay attention to whether the fruit trees are transparent enough and ignore the angle of the branches of the fruit trees. As a result, the angle of the fruiting main branch of the fruit tree is too small, which enhances the top growth ability of the young tree, and aggravates the baldness at the back of the young tree. If the angle is uncomfortable, then be sure to open the angle in time, in the early summer every year, the use of brace and other methods to expand the angle to ensure that the angle is about 60 degrees.

2. Improper tree shape

The main planting method of apple trees in many orchards is the close planting of tree rootstocks, while the fruit growers are mainly evacuated and stratified when pruning. The effect of this pruning method is very poor, which will lead to the decrease of fruit tree permeability, hinder flower bud differentiation and seriously reduce the flower and fruit rate. Therefore, for this kind of orchard, we should try our best to turn the fruit trees into small crowns and less graded trees. The pruning method should be changed reasonably according to the planting density and form, so as to improve the growth ability and yield of fruit trees.

3. Reasonable branch pulling

Pruning is a necessary work in apple pruning, but it also has certain technical requirements. The angle must be too large, if too large, it will lead to apple trees appear strips and other bad phenomena. If it is too small, the first phenomenon will occur. Therefore, we should deal with this kind of orchard flexibly according to the actual situation, and the fruit trees with little space should be thinned properly. On the contrary, fruit trees with appropriate space can use other methods to promote flowering and cultivate fruiting branches.

4. No distinction between primary and secondary

Many fruit growers are reluctant to cut off some strong branches when pruning, causing some of the main branches of the fruit trees 30 centimeters or more above the ground to come together. Resulting in the phenomenon of no distinction between primary and secondary, for this kind of orchard, we should pay attention to the spacing between branches when pruning. The distance between the main branches should be controlled at about 20 cm to ensure a clear hierarchy. Then expand the angle of the main branches with strong growth ability, and cut off the places where there are too many branches every year. For some 3-year-old auxiliary branches, it is necessary to control their growth ability and promote flowering and fruiting as soon as possible.

5. Pay attention to the tree potential

Different varieties of apple trees have different growth advantages, such as red Fuji apple fruit tip branch growth ability is relatively strong. If it is not pruned according to the tree situation, there are too many branches at the top, which is easy to appear the phenomenon of being strong at the top and weak at the bottom. Therefore, we should change the pruning method according to the tree potential, and this kind of fruit tree should remove the upper branches and reduce the number of branches and leaves in time. Improve the growth ability of the lower branches and increase the yield.

Finally, we should also pay attention to pruning in summer. Summer pruning has a great impact on the fruit of young trees. Therefore, under the premise of doing a good job of winter shearing, we also need to do a good job of eye injury, branch pulling and other basic summer shearing work in summer.
