PROBLEM TO BE SOLVED: To provide an industrial method for a cored bag-like vegetation mat for greening protecting a slope, a wall surface and an inclined plane through wrapping a vegetation base material with a bag-like sheet, using a wire and a core as a supporting body, and capable of corresponding with both an uneven surface and a smooth surface, preventing dryness and setting a water tank capable of improving a plant growth environment. SOLUTION: This industrial method for the cored bag-like vegetation mat comprises passing a horizontal wire through a cored bag-like vegetation mat which is made by putting a hollow core, a vegetation base material and a water supply pipe into the inside of a bag-like sheet, setting fixing metal fittings on both the ends of the horizontal wire followed by setting in the horizontal direction on a slope, a wall surface and an inclined plane, and fastening both the ends to a fixation surface with an anchor followed by fixing an intersection with a vertical wire in the vertical direction to a fixation surface with fixing metal fittings and an anchor. Furthermore, the method comprises setting a water tank on an upper horizontal plane of the fixation surface of the cored bag-like vegetation mat, setting a water collecting pipe set with a water collecting sheet on the upper part of the water tank, connecting the water collecting pipe and the water tank with the cored bag-like vegetation mat with a water supply hose, and setting the water tank capable of supplying water for a long period only an amount stored in the tank.
