A greening roll includes water-temperature-light controlling part, root growing part, water/root regulating part and seed-stacking part which is located in the water-temperature-light controlling part. The water-temperature-light controlling part is located on the top surface of the greening roll, the water/root regulating part is located on the lower surface of the greening roll, the root growing part is located in the cavity composed by the water-temperature-light controlling part and the water/root regulating part, and the seed-stacking part is located in the cavity of the water-temperature-light controlling part. The water-temperature-light controlling part further includes top-located irradiation reflecting part, temperature-water regulating part, light-preventing part and seed-stacking cavity. The present invention is suitable for the engineering protection and greening of engineering slopes, spoil and slag yards, embankments and the like, the water and soil conservation and greening of sandy lands, abandoned lands, borrow pits, slurry pond, mining fields, industrial and mining abandoned lands and the like, and the engineering thermal insulation and greening of building roofs and the like. |
