Apple trees are unevenly treated differently
In the process of apple cultivation and management, due to improper trimming or management; the imbalance of tree vigour is often caused, which brings certain difficulties for future trimming, high yield and stable yield. There are many types of apple tree imbalance, which need to be adjusted in pruning and management. Disclaimer: Some articles on this website are transferred from the Internet.

When the growth of the pruned tree is too vigorous, vegetative growth is dominant, which will cause insufficient flower bud differentiation and nutrition, which is not conducive to flower bud formation. When transforming this type of tree, it should be mainly "slow", and extend the length of the branch. Generally, it is cut at the weak buds. The branch angle of the main branch is increased. The branches on the back are removed, and the branches on the side are left. , To control the transport of nutrients to promote flowering.
Weak tree pruning When the tree grows too weak, it can be re-cut to stimulate its growth. Extension branches should be cut at full buds in the middle, with strong branches taking the lead, gradually increasing the angle of the extension branches, leaving less branches to prevent the growth of the branches, and leaving more branches on the back and sides to promote growth.
The pruned fruit tree of the partial crown tree has large branches on one side and small branches on the other. When partial crown growth occurs, the first one is to sparse branches below the large branch and sparse flowers above the small branch. It is the large branches that leave more fruits, and the small branches that leave fewer fruits. The fourth is that less fertilizer should be applied in the direction of the large branches, and more fertilizer should be applied in the direction of the small branches. It is strictly prohibited to use large cuts and large cuts to transform the tree shape.
The adjustment of the upper and lower weak trees mainly regulates such trees to suppress the strong and the weak. The adjustment measures for the upper branches are: thinning upright branches, removing overly dense branches and large branches, using weak branches to take the lead; opening the main branch angle; pulling some annual branches and some fruiting branch groups from the base Drooping branches. Adjusting measures for the lower branches: For the main branches that are too long and some branches can be retracted and rejuvenated, use strong branches to take the lead; for some main branches that are too low, you can directly remove them, pay attention to the oblique saw to leave the pile, and treat the wound in time; If the main branch is too large, lifting measures can be taken to raise the branch. The whole tree pays attention to strengthening the management of fertilizer and water and the prevention and control of diseases and insect pests.
The pruning of the strong and weak trees is commonly known as the "card neck tree". The main manifestations are as follows: the lower main branches have more and stronger growth, some of the main branches are even thicker than the middle trunk, and the upper branches are weaker. The main contradiction of this type of tree is in the lower part. Adjustment measures: properly remove 1 or 2 lower main branches; open the lower main branch angle; properly thin out the oversized branches and oversized branches on the lower main branches and use weak branches to take the lead; comprehensively use pull branches and re- branches on the lower branches , Take branches, circumcision, engraving buds, thinning branches, spraying flowers, and other measures to disperse the polarity, and promote the flowering of the lower branch; according to the situation, directly remove the middle and upper branches from the lower branch, transform it into a happy shape, transform After that, pay attention to strengthening the management of fertilizer and water, and do a good job of pest control.
