The invention discloses a cultivation method for increasing the yield of Mili pear, which relates to the technical field of fruit tree cultivation. The method in the technical scheme comprises the following steps of S1, varieties and seedlings, S2, planting, S3, soil management, S4, fertilizer and water management, S5, trellis construction, S6, shaping and pruning, S7, flower and fruit managementand S8, disease and insect pest control. The cultivation method has the beneficial effects that on the basis of the open center shape, good light distribution density is ensured under the tree shape;due to the uncertainty of the tree shape growth, a reform is made on the basis, heavy cutting back is done frequently, the growth of each growth branch is balanced, the light is more uniformly distributed, and the yield of parts in a sub-inner layer and an inner layer is increased. The light distribution in a canopy not only affects the yield, but also has a more prominent effect on the quality offruit. While the yield is increased, the proportion of high quality fruits in the parts in the inner layer and the sub-inner layer increases significantly because of the enhanced light intensity in the inner layer and the sub-inner layer.
