What are the problems with apple pruning?

The majority of the orchards do not pay attention to the opening angle of the saplings, resulting in a smaller angle of the main branch, resulting in a stronger superiority of the sapling at the top and an increase of baldness at the back. For these types of orchards, the angle should be opened as soon as possible. From May to June of each year, the main branch angles should be maintained by using methods such as support, pull, and other methods so that they can reach 60-70 degrees.

Inappropriate tree shape Most of the orchards are densely planted on the tree anvil, but evacuation and layering are often used on the plastic trim. This results in poor ventilation and light transmission, and flower buds are difficult to form. It is best to use small tree crowns, small skeletons, and low grade trees for pruning these types of orchards. The Qiaoqin dense planting garden should adopt the free-spindle shape and the sparse layer of the small crown; the dwarf dense planting garden should use the slender spindle shape. The tree height is controlled at about 3 meters, and the branch control is 70%-80% of the row spacing.

Improper branching after the Fuji apple pulls the branch, if the angle is too large, it will cause serious stripe phenomenon. For such orchards, they should be dealt with on a case-by-case basis. Those who have no space should be eliminated; if there is space, other measures such as don’t care, pull, shear, etc. can be taken to promote the flowering or cultivation of the result, and after the results Retraction.

Regardless of the primary and secondary times of pruning, most fruit growers have pity, resulting in clusters of base branches that are more than 40 cm above the ground. What's more serious is that the auxiliary and main branches are not clear. For this sort of orchard, the spacing between the layers should be taken care of when trimming, and the spacing between the main branches should be at least 20 cm or more, and should be orderly; the main branch with strong growth should be angled to reach 80-90 degrees if there is a branch left Many, can be removed year by year; to excessive support branches should be strictly controlled, can be used for 3-4 years, auxiliary support can be one or more girdling control prosperous, promote flowering results.

Unbalanced tree top Fuji apple has a strong apical dominance, combined with improper trimming, leaving too many branches on the top, which can easily result in strong and weaker tree vigor. For these types of orchards, upper branches or secondary branches may be properly removed to reduce the amount of upper branches and leaves; For the lower main branch, strong branches can lead and short sections can be appropriately shortened.

Neglecting summer cuts Most orchards only focus on pruning during the winter, but basically do not cut and let them grow during the growing season, delaying the results of saplings. To this type of orchard, it is necessary to do a good job on the basis of winter shearing, and do a good job in summer shearing such as eye injury, pulling branches, brushing buds, ring cutting, and twisting the tip.
