Abstract: A water culture device for peony is provided. The water culture device for peony includes an incubator. The incubator is internally provided with a sliding rack at a middle position. A servo motor is arranged on a right side of the incubator. Second rotating shaft levers are arranged on left and right sides of the incubator. Since the locating clips on the regulating levers and the planting baskets on the sliding rack are used cooperatively, the peony plants can be blossomed and positioned. Moreover, a downward putting action of the planting basket and a location clamping action of the locating clip are combined together and performed in one time through mechanical transmission, so that the trouble of stepwise operation is omitted, and the culture efficiency of peony plants is effectively promoted.
