Disclosed is a method for foresting a vertical wall and a highly-inclined surface and an aggregate container, a shelf assembly, and a water supply apparatus used for the method. The shelf assembly (10) includes a support unit (12) and a support plate (20). The support unit (12) has a fixing leg (14) fixed to a reinforcement soil layer (3), and a load support unit (16) is positioned at the front end of the fixing leg (14) and is forced against and supported on a vertical wall (7) or an inclined surface at the front end of the reinforcement soil layer (3). The load support unit (16) has a support leg (18) extending from its front end to be inclined in the opposite gravitational direction. The support plate (20) is supported on the support leg (18), and vegetation soil (40) is placed on the support plate (20). A horizontal supply tube (36) is positioned inside the vegetation soil (40) with both ends connected to vertical supply tubes (30), which have a predetermined interval between them. Water supply tubes (38) are installed on the horizontal supply tube (36). The water supply tubes (38) are filled with a filler (38), and pressure-reduction valves (37) are installed on connection tubes (37), which connect the water supply tubes (38) and the horizontal supply tube (36). The shelf assembly (10) can support the load of the vegetation soil (40) more efficiently, and water is supplied into the vegetation soil (40) more effectively.
