Ecological concrete slope protection structure with vegetation and water holding performance and application

The invention discloses an ecological concrete slope protection structure with vegetation and water holding performance and application. The slope protection structure comprises a grid-shaped framework arranged along a slope soil body, a hydrophilic porous recycled aggregate layer laid in the grid-shaped framework, a vegetation water-holding type ecological concrete layer and a vegetation type ecological concrete layer, wherein the vegetation water-holding type ecological concrete layer and the vegetation type ecological concrete layer are arranged on the hydrophilic porous recycled aggregate layer from bottom to top. The latticed framework is formed by vertically and horizontally intersecting a plurality of lattice beams to form a plurality of rectangular lattices, the vegetation water retention type ecological concrete layer and the vegetation type ecological concrete layer are respectively filled with a first nutrient medium layer, a seed layer is arranged on the first nutrient medium layer, and a second n
