①The basic structure of the tree. The cylindrical shape has an upright or curved central trunk, on which 15 large and medium-sized fruit-bearing branch groups grow in turns. They are not divided into layers and have no main branches. After forming, the tree is about 2.5 meters tall and has a crown diameter of 1.5 to 2.0 meters. Cylindrical shape.

② Plastic surgery technology. After planting, set it to dry 100 centimeters away. At the same time, wipe off the buds below 60 centimeters. Within the height range of 60 to 100 centimeters, select a bud that is distributed in a wheel shape on the central stem every 10 to 15 centimeters. The remaining buds should be wiped off. go. During the germination period, all selected buds will be carved. Except for the central trunk, all other branches are flattened to form the fruiting branch group. Leave about 10 cm of each side branch for heavy pruning when it grows to about 30 cm, and moderate pruning of the central trunk for every 50 cm of growth. When pruning in winter and spring, cut each branch group appropriately and shorten it to a medium length. Control the crown of the tree to maintain the growth of new shoots at about 20 cm. Control competing branches, leggy branches and upright branches. They can take shape in 3 years and lose their heads in 4 years.
