Early-stage high-yield pruning method for dwarf sweet cherries

The invention relates to the technical field of fruit tree pruning, in particular to an early-stage high-yield pruning method for dwarf sweet cherries. Comprising the steps that in the first year, trunk fixing, bud carving, bud picking and small main branch angle opening are conducted on trunks, pinching is conducted twice at the depth of 20-30 cm, and pinching is conducted three times on non-small main branches; in the second year and the third year, trunk fixing, bud carving and bud picking are continuously conducted on the trunk extension branches, small main branches and non-small main branches are treated in the last year, bud carving is conducted on the small main branches, and new shoots germinating on the small main branches are pinched three times; in the fourth year, trunk extension branches can be adventitious, weak trees or weak trees are cut back, branch lacking parts are carved into buds, the trunk extension branches are pinched for three times, and new shoots on small main branches in subsequen
