Poor soil slope greening slope protection system and construction method

The invention discloses a poor soil slope greening slope protection system and a construction method. The greening slope protection system comprises an ecological isolation pad structure, a soil layer and an ecological base material layer. The ecological isolation pad structure comprises an isolation layer, soil activity-increasing organic matter and a reinforced net pad layer, the space between the reinforced net pad layer and the isolation layer is filled with the soil activity-increasing organic matter, and the ecological isolation pad structure is fixed to the slope surface of the side slope through ground anchors. The soil layer is filled between the ecological isolation pad structure and the ecological base material layer, and vegetation is planted on the ecological base material layer. According to the method, the greening slope protection problem which is not beneficial to plant root system development in poor soil texture is solved, water prevention, water drainage and slope protection can be achieve
