1. Pruning method in the young tree period: The newly planted plum tree is in the young tree period, which is very vigorous and the main branches are easy to form. Therefore, attention should be paid to make it form a good tree shape and expand the crown of young trees when pruning. In order to ensure the yield of early fruit trees, pruning should not be too heavy, so as to achieve the purpose of transporting nutrients normally and slowing down the growth of buds. For new seedlings, short pruning can be used, that is, cutting off a part of annual branches, about a quarter, which can slow down the growth of branches, produce more short and medium branches, and cultivate various types of trees. There are great differences in the growth ability, growth direction and extension direction of annual branches after short cutting. For fully cut upright branches, it is easy to produce vigorous branches after short cutting, which can be used to cultivate the trunk of trees; Other derived weak branches can be used for culture as the result group. Although short pruning is not conducive to the formation of flower buds of fruit trees, moderate short pruning of weak branches can increase the total number of bud branches of fruit trees and increase the yield of fruit trees.
2. Pruning method at the initial stage of fruiting: Plum trees planted for two to three years have entered the fruiting period and have begun to form yield. The purpose of pruning in this period is to improve the tree shape, expand the crown range and cultivate as many fruiting branches as possible. Because Fujian is warmer in winter than most northern areas, but the temperature is still low, so pruning should try to shorten the main branches and reduce the density of branches, which can improve the ventilation conditions of plum trees, increase illumination and save nutrients. But the number of truncation should not be too much, so as not to cause unnecessary growth. Observe the growth direction and position of branches inside the crown, and try not to cut them as long as the direction is appropriate.
