%X Based on the "composite plate" technology, straw was used as the main raw material to produce a kind of slope support that can recover green. The seed germination experiments of Festuca elata Keng showed that the eco-slope support can be used as the substrate of plant growth and can supply nutrients for plant growth. When the rainfall rate was 0.5 L/s and the slope was 55o, the eco-slope covered with vegetation could effectively delay the runoff retention time. The average removal efficiency of the eco-slope was 85% for suspended solids. The average removal efficiencies of the eco-slope were 93% and 84% for water-soluble phosphorus and sediment combined phosphorus, respectively. The bio-safety tests showed that straw eco-slope was environment-friendly. The development of straw eco-slope could make full use of straw, thus could decrease environmental pollution from straw-burning.
