The invention discloses a cultivation method for kadsura. The method comprises the following steps: treating inter-planting land: filling a gully between two trenches with a medium; in the day before inter-planting, fully mixing the following components at weight ratio: activated carbon, cane sugar, naphthylacetic acid and indolebutyric acid, and then uniformly spraying to the medium; trans-planting: trans-planting at the ratio of pistillate plant to staminiferous plant of 6:1; pinching and topping: fertilizing at fixed period. According to the invention, before inter-planting in the prior art, sandy soil, straw ash and plant ash are added into the trenches so as to form the loosened and fertile growth soil for kadsura; insecticides, including cypermethrin, fenvalerate, isocarbophos, phoxim, hexythiazox, diluents and the like, are added, so that the roots and leaves are prevented from being damaged by insects; in the day before inter-planting, activated carbon, cane sugar, naphthylacetic acid and indolebutyric acid are sprayed to the trenches, so that the growth of the root of the kadsura is benefited; after the completion of inter-planting, the kadsura is periodically fertilized, different fertilizers are applied in different periods and the growth of the kadsura is benefited.
