NOVELTY - Method for recovering damaged slope using a strip type planting device comprises cleaning a damaged slope by removing dangerous rock gravel, then smoothening the slope, reducing the slope size, filling 1.5-2 meters per bag with planting substrate and base material from bottom to top, sealing the bag using a suture line, and transporting the sealed bag from a disk or stacked barrier into the slope.    USE - The method is useful for recovering damaged slope using strip type planting device (claimed).    ADVANTAGE - The method is capable of recovering the damaged slope using eco-friendly strip type planting device with instant installation, less energy consumption, good anti-erosion effect and materials containing low carbon in a convenient manner.    DETAILED DESCRIPTION - Method for recovering damaged slope using a strip type planting device comprises cleaning a damaged slope by removing dangerous rock gravel, then smoothening the slope, reducing the slope size, filling 1.5-2 meters per bag of the strip type planting device with planting substrate and base material from bottom to top, and then sealing the bag using a suture line. The strip type planting device comprises an inner planting bag, an outer planting bag, and a covering layer. The inner planting bag has slightly smaller diameter and similar length when compared to the outer planting bag. The inner planting bag is placed in the outer planting bag. A side of the inner planting bag is stitched to the outer planting bag using a thread. The stitched side of 5 cm length is arranged with a planting hole. The planting hole has lengthwise pitch of 6-10 cm, and transverse pitch of 5-8 cm. The outer planting bag is equipped with the covering layer, which is bonded to a silk ring placed at an interval of 50-80 cm. The inner planting bag is filled with a planting substrate. The outer planting bag is filled with a base material. The inner planting bag is stitched with a high strength non-woven geotextile. The outer planting bag is stitched with a 200-300 g of perforated Kraft paper with a side slope ratio of less than or equal to 1:0.75, 300-400 g of perforated Kraft paper with side slope ratio of 1:0.25-1:0.75, or 400-450 g of perforated Kraft paper with side slope ratio of more than 1:0.25. The planting substrate comprises 1 ton of planting soil, 20-30 g of water retention agent, 15-20 kg of peat, 20-30 kg of compost, 10-20 kg of oat, and 10-15 kg of rice hull or crushing rice. The covering layer comprises 15% of 150-200 g of nitrogen-phosphorus-potassium compound fertilizer, 100-150 g of urea, and 2-3 kg of calcium superphosphate. The base material is obtained by mixing 20-40 g/square meter of arborescent plant seed of damaged slope vegetation area, 5-15 g/square meter of calcium lignosulfonate, 0.5-1 kg/square meter of paper pulp, 15% of 5-10 g/square meter of nitrogen-phosphorus-potassium compound fertilizer and 20-30 meshes of soil, and then adjusting the humidity and making into small balls. The silk ring is fixed to the strip type planting device using a zinc-plated flat wire, or a copper wire.
