How to plant plum trees for pruning

① plastic surgery. The tree can be shaped by natural happy shape, natural formation of multiple main branches or "Y" shape. The fixed stem height of young trees is 30-50cm. Leave 5-6 buds as the main branch after sprouting, and leave 40cm to top when the length of the main branch is 50-60cm. There are 2-3 permanent main branches in August, and the surplus 2-3 main branches are pulled out to make them droop, which will blossom and bear fruit in the following year. In the later stage, they were cultured into large and medium-sized fruiting branches as appropriate.

② pruning. 1) pick the heart. When the new shoot grew to 40-50cm in the same year, it reached the top and picked the heart 3-4 times a year. When the growth of the main branch is unequal, the strong branch lengthens the head and picks the heart early, while the weak branch picks the heart late. The coring of the accessory shoot of the fruit platform in the prosperous period can increase the acne rate and promote the increase of the fruit. 15-20 days before the new shoots stop growing in autumn, the top shoots are removed to enrich the branches and promote the fullness of flower buds. 2) pruning during the growing period. Upper dorsal branches and competitive branches should be removed in time. If you want to cultivate into the fruiting branch group, from the beginning of May to the middle of June, the length of 5-15cm will be truncated twice in a row. In autumn, the germinating medium and long branches will be thinned, leaving short fruit branches and leaf branches, and then cultured into the fruiting branch group. Weak branches, parallel branches, diseased branches, etc., should be removed from the base in time during the growing period. 3) pruning during dormancy. The young trees of Brown plum grow vigorously and stand upright. Pruning should be based on the principle of "light cutting, lengthening and enlarging the angle". The backbone branches and extended branches should be slightly short-cut, and the auxiliary branches should be kept slowly as much as possible, without starting, and too dense branches should be removed. In order to weaken the tree potential, the method of pulling branches is used to increase the angle of the main branch, which generally requires an angle of 45-50 degrees for the main branch and 60-80 degrees for the auxiliary branches. In a word, young trees should pick the branches continuously for many times in order to promote the formation of short fruit branches and bouquet-like fruit branches, increase the number of branches and form an open crown as soon as possible. Adult trees should control the growth of the upper part of the crown, sparse more branches, and intercept weak branches to take the lead.
