PROBLEM TO BE SOLVED: To ensure taking-root of the root of a planting plant, while hastening growth by changing the structure or members and the quality of materials on the surface side exposed to atmospheric air and the rear side brought into contact with a natural ground in construction works, in which borrow-material bags are installed on the face of a slope and planting is conducted. ;SOLUTION: In the tree-plant sapling planting method of the cut slope, the hard rock-mass slope, the mortar-sprayed layer or the like and the greening slope in which saplings are planted on the tree-plant slope, surfaces 4 exposed to atmospheric air of the bag bodies for borrow materials having purse-shaped opening sections 3 are manufactured of corrosion- resistant sheets in which light-weight aggregate, foamed styrol, a foamed styrol volume- reduction material or heat-insulating raw materials 5 such as crushed stones, gravel or the like are housed. The roots of planted plants pass through rears 43 brought into contact with the face of the slope 1 by growth then, and are manufactured of a raw material capable of supplying moisture from natural ground, water retention holes 6 are bored in the horizontal direction of the face of the slope on the side on which the bag bodies are mounted, and water retention ropes and other water retention members 7 are inserted into the water retention holes.;COPYRIGHT: (C)2001,JPO
