Wangshu
Performance: The tree has more branches, the spring shoots are longer, flower buds are difficult to form, the leaves are larger, and the fruit is smaller.
Adjustment measures: control the fertilizer and water, reduce the amount of nitrogen fertilizer; appropriately thin out the dense and prosperous branches; comprehensively use the branches, pull branches, cut buds, ring cutting, spray stimulating flowers and other measures to disperse the polarity and promote the formation of flower buds as much as possible; Keep more fruit and press the crown with the fruit.
Wild tree
Performance: The whole tree has a lot of shoots, some of the annual shoots are more than 2 meters in length, and the annual growth is very large; the whole tree has no fruit or flowers, the branches are hard, and the leaves are large.
Regulation measures: strictly control the fertilizer and water, do not fertilize or water throughout the year; root cutting, girdling, etc. can be adopted; some large branches can be removed with tree shape transformation before germination in early spring.
Up strong down weak tree
Performance: The upper branch grows vigorously, the main branch is thicker, the branch angle is smaller, the amount of branches and leaves is larger, and it is difficult to form flowers and fruit; the lower branch grows weakly.
Adjustment measures for the upper branches: thinning out denser upright branches, removing large branches and large branches on branches that are too dense.
Adjustment measures for the lower branches: the main branches that are too long and part of the branches can be retracted and rejuvenated; the main branches that are too low can be removed; for the main branches with too large opening angles, the branches can be lifted up.
Down strong and up weak tree
Performance: The lower main branches are more and more vigorous, and the upper branches are weaker.
Adjustment measures: properly remove 1 to 2 lower main branches; open the angle of the lower main branches; appropriately remove the excessively large branches and the excessively large branches on the lower main branches; comprehensively use pulling, transferring, and holding branches on the lower branches. Measures such as ring cutting, carving buds, thinning branches, etc., disperse the polarity and promote the flowering and fruiting of the lower large branches.
