The growth of fruit trees is different, and there are great differences in size, height, posture and orientation, so we should choose the correct direction, orientation and angle of trees in the process of pruning. After the growth of plum trees entered the full fruit stage, the main branches had grown up and the growth of the trees was relatively mild. At this time, improving the nutritional composition of plum trees is a principle that must be followed when pruning. After pruning, the morphological structure of plum trees has been formed, which is the highest yield period of plum trees.
Maintain tree potential balance, increase branching order, and promote flowering and fruiting. Pruning in winter is carried out in dormant period, and supplementary pruning is carried out on the basis of pruning in summer, so as to keep the shape and balanced growth of the tree, maintain the subordinate relationship between branches at all levels, and prune plum trees. Plum trees generally need pruning two or three times in the whole growth process, and pruning needs to be carried out in different periods. Generally speaking, there are two seasons and four growth stages. Big scissors in summer and small scissors in winter.
Plum trees can choose natural round head shape and slender spindle shape to keep the central trunk, and choose 3~5 main branches at the base instead of secondary main branches. Side branches are arranged on the main branches in turn, and bearing branches or bearing branch groups and nutrient branches are planted on the side branches. My family doesn't pay much attention to pruning green plums and red plums, just stagger the branches and dwarf them, and don't leave too many buds. Pruning can adjust the relationship between growth and fruiting of plum trees, establish a reasonable tree structure, improve ventilation and lighting conditions, increase yield, improve quality, make young trees grow early and bear fruit early, make trees stable and high-yield, delay aging and prolong life.
