How to trim the sparse layering shape of big cherry crown?
① The basic structure of the tree. The small crown has a central trunk, with a height of 3.5 meters and a trunk height of about 60 cm. The whole tree has 5-6 main branches, which are divided into upper and lower layers. The first layer has three main branches with an opening angle of 70-80 degrees, and each main branch is planted with two lateral branches and several bearing branch groups, and the lateral branches are alternately distributed on both sides of the main branch with a spacing of 40-50 cm; The second layer has 2 ~ 3 main branches, the opening angle is 60 ~ 70, the interlayer spacing is 1.2 ~ 1.5 m, and the upper side of the main branch faces the large and medium-sized fruiting branches.

② Plastic surgery technology. 80 cm after planting, 3 ~ 5 branches germinated in the same year, 3 branches with reasonable distribution and large angle were selected as main branches, and the rest were slowly blossomed or thinned. When pruning in the winter and spring of the following year, the extension branches of the main branch were cut short at 50 ~ 60 cm, and the central trunk was cut short at the main branch 1/3, so the first layer of the main branch 1 ~ 2 side branches were selected purposefully. In the third year, according to the distance between plants, the main branches on the first floor have short cutting space, which can be put slowly after overlapping. For the second layer, cut the main branch at the branch 1/3 to promote branching, and choose 1 ~ 2 side branches to establish a good fruiting branch system in the crown. Through the adjustment of various branches, it can be cultivated into a small crown and sparse layer after 3 ~ 4 years, and it will fall down in the fifth year.
