In general, the tree shape of papaya is single stem, natural, close to round head or spindle shape. When transplanting young trees, the trunk should be fixed at 60~ 80cm from the ground, and the lower branches should be drained in time to keep the middle trunk growing upright; Within 1-5 years after the stem is fixed, 40-50 cm of the extended branches of the central stem are cut off every year, and 2-4 branches dispersed with each other are selected as the main branches. After the basic tree shape is formed, it can be properly thinned to promote downward control and make the crown open and round; Excessive pruning will affect the yield and damage the tree posture. Prune weak branches, erect branches, cross branches and parallel branches in early spring; After flowering, cut off long and short branches, and remove useless branches, too dense branches, dead branches and weak branches. ：
