How to prune the imbalance of apple tree growth

Apple trees are very common in China, and there are many varieties of apples, which have different planting areas in different parts of our country. When planting apples, many fruit growers will find that the growth of apple trees is out of balance due to improper management, natural environment and other factors. At this time, we have to adjust the growth of apple trees through pruning to ensure the balanced growth of apple trees. So if the growth of the apple tree is out of balance, how to prune it? Let's take a look at it.

1. Strong on the outside and weak on the inside

The strong growth of the outer branches of the apple tree, the excessive growth of the branches and the small angle of the extended branches will seriously affect the permeability of the inner bore branches of the apple trees. As a result, the permeability of the inner branch is too poor, the growth is weak, and it dies when it is serious. For this kind of fruit tree which is strong on the outside and weak on the inside, the first step is to adjust the growth angle of the main and lateral branches. Increase the number of branches of the main side branches, and then cut off the overdense and long branches and perennial notes around the crown. Improve the permeability of the inner chamber of apple trees, promote the growth of branches, improve the accumulation of nutrients, and enhance the growth of fruit trees. Ring cutting can be used to promote flowering and prevent vigorous growth, and it can also be cut short in winter to cultivate fruiting branches.

2. Strong at the top and weak at the bottom

The perennial retention of strong branches and the truncation of strong buds will strengthen the growth of branches and grow too fast, resulting in the phenomenon of strong and weak apple trees within 3 years. When the first layer is cut short and thinned improperly, it will lead to a sharp decline in the number of branches and leaves of apple trees, a significant decline in growth rate, and the expansion of the crown will also be hindered. When you find this kind of strong and weak tree, you should remove the Wang Zhang note in the middle and upper part of the trunk in time, and then keep the mediocre branch. Slowly flatten the other branches and remove the management strips on the back of the backbone branches. Cut short the redundant branches to increase the weight of the branches and enhance the growth of the branches.

3. The lower strength is higher than the weak

Contrary to the superior fruit trees, if the weak branches and weak buds are retained all the year round, the growth of the upper branches is weak, while the lower branches are strong, it will certainly lead to the lower strong and the upper weak. If the three main branches at the base grow strongly and grow together, it is easy to cause the apple tree to pinch the neck. At this time, we have to restrain the growth of the lower branches, and the lower branches should choose the weak branches to remove the prosperous and long branches. Then improve the growth angle of backbone branches, ring peeling to promote flowering. Avoid the overgrowth of the lower branches and improve the fruit rate of the first layer of main branches. Attention should also be paid to cutting off the over-long and over-dense branches of the upper branches and truncating them to increase the number of branches and leaves.

4. The basal main branch is weak.

For some fruit trees with weak overall growth, it is necessary to choose weaker branches to cut them short. It is also necessary to truncate the extended main side branches and cut off a small number of erect, dense long and other long branches on the back of the tree. Keep the rest of the branches and try not to leave flower buds to promote the vegetative growth of apple trees. For some overgrown fruit trees, on the contrary, more branches should be thinned, which are mainly competitive branches and overdense long branches, retaining most of the flower buds. Cut the branches, increase the amount of flowers and fruits, and use the fruit to control the growth of fruit trees.

The above is a brief introduction to the apple tree growth imbalance how to prune, in fact, the apple tree growth imbalance is mainly caused by inadequate pruning work. Therefore, when we plant, we must do a good job in pruning in advance to avoid some growth imbalance and increase labor costs. That's all for today's introduction. This article is for reference only.
