The invention discloses a kiwi fruit frame-free cultivating method, and belongs to the technical field of plant cultivation. The method includes the following steps of (1), variety selection, whereina female plant variety with short junction spacing is selected; (2), garden establishing and planting, wherein 110-120 plants are planted per mu, the line spacing is 2.5-3 m, and the row spacing is 2m; (3), first year management, wherein in the spring germination period, 2-3 buds are reserved above each junction for severe pruning, after germination, strong single branches are selected and reserved as trunks, pinching is carried out when the trunks grow to 1.2-1.8 m high, when top leaves grow to be mature, the trunks are reserved to be 0.8-1.2 m high in a centralized mode for cutting, and waiting for the trunks to germinate again is carried out; after each trunk germinates, four branches are selected and reserved, wherein the four branches comprise an upright branch, growing upwards, reserved at the top end of the trunk and further comprises three alternate branches, pinching is carried out when the four branches are 0.8-1.2 m long respectively, the alternate branches are reserved tobe 36-45 cm long when the top leaves are mature for cutting, and the branch spacing of secondary branches is kept at 20-25 cm; during winter pruning, bases of the three alternate branches are 8-12 cmlong, lateral buds are reserved for cutting, and the plants grow into kiwi fruit undershrub tree bodies. No shed frame needs to be built, and the cost is reduced.
