An air-conductive rotary sprinkler includes an air-conductive rotary sprinkling device and an air/fluid supply assembly. The air-conductive rotary sprinkling device further includes a main housing tube, an inner rotary tube and a rotary spray head. The rotary spray head includes a spray-head casing connected with the inner rotary tube and a guide plug installed inside the spray-head casing and further including a helical actuating groove, a helical conductive groove, a central channel and a sideway channel. The fluid in the fluid-conveying pipe can be sprayed along the base axis by the pressured airflow from the central channel, the rotary spray head is rotated by the pressured airflow from the helical air channel, the spray direction of the fluid originally flowing along the base axis is altered by the pressured airflow from the helical conductive channel so as to spray out of the rotary spray head in a rotary manner.
