The invention relates to a vegetation slot rotary window, comprising a frame body, a rotary window board assembly and a vegetation slot assembly. A shaft seat assembly is disposed on a middle position of the frame body. A rotary shaft pipe which is disposed inside the rotary window board assembly includes two ends top-bottom coupled to the shaft seat assembly and opened with a ventilation pore on a surface thereof. A support board assembly which is disposed on each side of the rotary shaft pipe is disposed with a sliding slot assembly. Further, each support board assembly is clamped and fixed by a transparent board assembly at both sides thereof so that the support board assembly is clamped between the transparent board assemblies, and one side of each transparent board assembly is fixedly connected to the rotary shaft pipe. The vegetation slot assembly is disposed with a slot on surfaces thereof respectively, and a sliding-slot aperture assembly which is disposed below the vegetation slot assembly is corresponding to the sliding slot assembly of the support board assembly. With the constitution of the above-described components, the rotary window board assembly is capable of being movably rotated and opened, and the vegetation slot assembly is capable of being slidably extracted to conveniently replace plants by means of the engagement of the sliding-slot aperture assembly of the vegetation slot assembly and the sliding slot assembly of the support board assembly. When the rotary window board assembly is closed, the ventilation effect can be achieved via the ventilation pore of the rotary shaft pipe. Accordingly, the invention provides a vegetation slot rotary window constituted by cooperating environmental greening conception with hardware, thereby facilitating processes of cultivating, watering and irrigating plants and attaining efficacy of landscape greening.
