<P>PROBLEM TO BE SOLVED: To provide a double film water flow curtain with lining for air-conditioning which can prevent the lowering of light transmission due to the adhesion of sprayed water not only to the lined curtain but also to the inner surface of a green house outer cover in the green house using the water curtain, and can prevent the deterioration of water-spraying effect due to the blowing of wind, when water is sprayed with sprinklers or watering tubes. <P>SOLUTION: There is provided a flow-watering tube cover 1 prepared by covering a watering tube 2 having a proper width in a double tube shape. The watering tube 2 is produced by forming longitudinally continuous slits or properly shaped holes 18 at proper height positions as a water flow device set on a cover film, comprises a polyolefin-based resin film having a visible light reflection factor of not less than 50% and properly shading, and has proper holding portions in the longitudinal direction, or is occasionally disposed in a baggage-like shape divided on both the right and left sides. <P>COPYRIGHT: (C)2011,JPO&INPIT |
