Nursing structure of large slope rock side slope based on rainwater collecting bag

The utility model discloses a nursing structure of a large slope rock side slope based on a rainwater collecting bag. A ring-shaped guide bar is welded to a frame in advance through a module design of the nursing structure, when the nursing structure is installed in site, a nursing structure module just need to be fixed on a mountain slope through anchor fixing holes, and a plant-growing member is clamped on the inner side of the ring-shaped guide bar, so that the installing process can be simplified, and the installing difficulty is reduced. The ring-shaped guide bar is fixed on the frame, and the cone plant-growing member is clamped on the inner side of the ring-shaped guide bar in a rotating mode, so that the nursing structure module is simple and light and reduces the planting difficulty and cost. The rainwater collecting bag is arranged below the plant-growing member to collect the rainwater seeping from openings of the plant-growing member, so that the rainwater fills the rainwater collecting bag automatically when it rains to be stored to use. An opening at the lower end of the rainwater collecting bag is connected with a drip irrigation pipe, and in a dry season, a control valve can be opened to supplement water for the slope needing to be nursed through the drip irrigation pipe to ensure the water needed for the growth of vegetation and reduce cost of water transportation.
