The invention discloses a high-yield shape pruning method of green prickleyash. The high-yield shape pruning method comprises the following steps of: for earsh, pinching and remaining the trunk, leaving robust buds on the trunk; and pinching again, remaining main branches and culturing side branches on the main branches, pinching so that side branches can grow up and robust bearing branches are evenly distributed on each secondary main branch; for fruiting tree, after harvest of green prickleyash, thinning out redundant boughs, and carefully pruning branches in the crown so that the branch groups are evenly distributed; short cutting the bearing branches to the range of 3-6 cm and cutting off excessively fruiting and aging bearing branches; remaining robust buds on each branch and removing redundant buds; and removing the side branches at the base part of the trunk; and for old tree, removing old branches and breeding new branches, and prolonging the life of the tree body and the fruiting life of the tree. The high-yield shape pruning method is characterized in that shape pruning is performed at earsh, fruiting and old stages of green prickleyash, respectively, so that the tree groups are appropriate in density, the branches are even in distribution, and the crown is good in ventilation and light transmittance effects; besides, there are few plant diseases and insect pests; the yield is high; the economic service life of the green prickleyash tree is long; and fruiting can be brought forward; therefore, good quality, high yield, stable production, and low consumption are realized.
