With the rapid development of the medlar industry, the expansion of planting area and the problem of labor shortage are increasingly remarkable, and the labor cost of a medlar garden accounts for 76% of the total production cost. The tree-shaped spaces such as natural semicircular, three-storey buildings and the like which are used for a long time are greatly utilized, and high yield is facilitated, but the following defects exist: (1) the tree body is large, the skeleton level is multiple, latent buds and adventitious buds on the bone trunk branches are easy to extract, the back branches are multiple, measures such as pinching and bud picking are needed to be conducted frequently for management, and the labor amount is large; (2) the volume of the tree crown is large, the quantity of peripheral branches and leaves is large, and the leaf curtain layer is thick, so that the light quantity of the blades in the inner chamber is very small, and ventilation and light transmission are not facilitated; (3) the pruning technology is complex, the skeleton level is multiple, the requirements on the angles and the positions of the main branches and the branch groups are high, and the problem of yield reduction caused by the fact that a grower cannot easily master the pruning technology is many.
