Hello! Plum trees usually have three main branches. When planting in the same year, the stem was fixed at 80 cm, and three new shoots with the same growth direction were selected to cultivate the main branches. When pruning in winter, choose the main branch to be optimistic about the bud direction, cut 60 cm, do not cut the delicate branches other than the main branch, and cut it close to or thicker than the branch weight of the main branch 10 cm. In the second year, protect the three main branches, prolong the normal growth of new shoots, select 1 anticline new shoots to cultivate lateral branches, and the first lateral branch on the three main branches should be in the same direction. When cutting in winter, 50-60 cm of main branch extension branches are cut off, 40-50 cm of lateral branch extension branches are cut off, and competitive branches or back branches are thinned or shortened; In the third year, the new shoot of the main branch is extended and continues to grow, and the second branch is selected opposite to the first branch under the extended branch of the main branch. The method of pruning in winter is the same as that of the previous year. In addition to pruning the main lateral branches, strictly control the competitive branches and the upright branches on the back, supplemented by light cutting and slow release of the main branches, and increase the angle by pulling branches to promote flowering. Remove the branch force from the main branch, make the branch force weaker, slow down the branch taking and promote flowering and fruiting. Three side branches are left on each main branch to basically complete the tree shape, and no side branches are left above the third side branch, so that the main branch keeps uniaxial extension. When entering the full fruit stage, rows should not be crossed and closed, the cross branches should be retracted, the light path between rows should be opened, and the light band above 1 m should be maintained in the growing season, so as to make the illumination of orchard groups more reasonable and lay a good foundation for high yield and high quality.
