Trim and reshape:

The most commonly used tree shape of Ulm plum is "natural and happy shape". After the graft survives, when the seedlings grow to more than 1 meter, cut them off at about 65 cm. In the growing season of the following year, the first main branch is selected at about 45 cm from the ground, the second main branch is selected at 10 cm from the top, and the third main branch is selected at 10 cm from the second main branch. The three main branches should be evenly distributed in different directions, the distribution angle is about 120°, and the opening angle should be 45°.

After the three main branches are selected, the remaining branches can be retained in a small amount as supplementary branches, and the rest are removed. In the second year of winter pruning, the three main branches can be short-cut, the length of the short-cut is 1/3 of the length of the branch. When short-cutting, pay attention to the balance of the canopy, the strong branches should be lightly cut, and the weak branches should be cut again. Leave external buds under the mouth.

In the spring of the third year, some new branches of the extended branches adjacent to the new main branches should be removed in time, and some strong branches should be retained. In winter shearing, the main branches should continue to be shortened and some side branches should be kept. These side branches should be The direction is the same, or all clockwise, or all counterclockwise, no cross branches.

The remaining side branches should also be properly shortened and gradually cultivated into flowering branch groups, and the spacing between flowering branch groups on the trunk should not be less than 30 cm. During the cultivation of the flowering branch group, it is necessary to pay attention to the combination of middle and long branches and short branches, so as to maximize the growth of flower buds.

After the basic cultivation of the canopy is formed, the pruning is mainly divided into summer pruning and winter pruning. Summer pruning is generally carried out in June after flowering. It is mainly to top off the long branches, and to cut the branches that have already been flowered, Only 3 or 4 buds at the base are left to bring the newly germinated branches closer.
