The subject innovation is, install the side of the Greenhouse to be provided with a drain hole at regular intervals eda skirt vinyl elevated by a separate take-up device Greenhouse my, flow falling rain, dew and condensation be such as to effectively rapidly drained along the external surface of allow to fundamentally intended to block the structural stability of the frame of the house and the facilities of the House vinyl tearing and sagging vinyl skirt and at the same time ensuring a smooth sphere of the same sex retractor. A look at the structure of the facilities house skirt plastic (20) with the drain hole of the subject innovation, the overall shape is wound in a state with a certain width (B) in the branch tube 22 as in the conventional plastic not to be supplied to the farm materials examples of the roll-in state, and the longitudinal direction (L) a plurality of drain hole 21 is arranged at regular intervals in the form. The subject innovation are facilities, install the side of the house quickly separate flowing down along the inner, the outer surface of by Greenhouse to have a drain hole at regular intervals eda skirt vinyl elevated by the take-up device rain, dew and the number of condensation, etc. effectively drain to fundamentally blocked by the frame such as structural stability of the facility and tear of the House vinyl house deflection skirts and vinyl, and it can achieve the effect of ensuring a smooth sphere of the same sex volute teeth device.
