The invention relates to a planting rotary device, the main structure comprising a frame body, at least one potting component, at least one water injection device, at least one positioning shaft longitudinally penetrating the potting component, at least one water bearing container located below the potting component, a plurality of water spray pipes connecting the potting assemblies, and at least one rotating member connecting the frame body and the positioning shaft. With the above structure, the water body of the potting assembly is directly flowed to the water spout pipe, and the output water body is impacted by the water body in the water receiving container, and the positioning shaft is driven by the reaction force generated to rotate the potting assembly relative to the frame body. Thereby, the potting assembly is naturally rotated by the reaction force of the water without adding additional power, thereby simplifying the structure, saving energy, and providing uniform illumination of the plant.本新型為有關一種植栽旋轉裝置，主要結構包括一框架本體、至少一盆栽組件、至少一注水裝置、至少一縱向穿設盆栽組件之定位軸桿、至少一位於盆栽組件下方之承水容器、複數連通盆栽組件之噴水管、及至少一連結該框架本體及該定位軸桿之轉動件。藉上述結構，直接將盆栽組件的水體流向噴水管，並使輸出之水體衝擊承水容器內之水體，而藉產生之反作用力帶動該定位軸桿，使該盆栽組件與該框架本體相對轉動。藉此，使盆栽組件利用水的反作用力自然旋轉，而無須再施加額外的動力，達到簡化結構、節約能源、及提供栽種植物均勻受光之目的。
