GREENING VEGETATION SUBSTRATE FOR BARE SLOPE

PROBLEM TO BE SOLVED: To protect the bare ground by providing vegetation stuck sections stuck with vegetation seeds and peripheral natural vegetation intrusion sections stuck with no vegetation seed in turn on a net. SOLUTION: A fabric 3 of thin cotton or the like is stuck to the back face of a long vegetation net 2 by a water-soluble paste material, and many small-diameter bags 4 filled with a vegetation base material 5 are provided nearly in parallel at the prescribed intervals in the width direction of the surface of the net 2. Vegetation stuck sections 6 stuck with vegetation seeds, a fertilizer and a soil improving material and peripheral natural vegetation intrusion sections 7 stuck with nothing are provided in turn in the longitudinal direction of the fabric 3. The fabric 3 is dropped from the net 2 at the time of a rainfall, and it covers the slope soil surface to prevent the movement and flow-away of soil. The stuck sections 6 prevent the movement and flow-away of seeds, and the intrusion sections 7 reliably fix flown-in seeds. The vegetation stuck sections 6 are greened at an early stage and can prevent the bare ground from being eroded and collapsed by the rainfall, and the peripheral natural vegetation intrusion sections 7 decrease the flow velocity of flowing-down water with many small segments and can suppress the erosion and collapse of the bare ground.
