This invention provides a method and application for the ecological restoration of rock mine slopes in ecologically fragile high-altitude areas, specifically relating to the field of ecological environment restoration technology. The ecological restoration method includes: leveling the rock mine slope in an ecologically fragile high-altitude area, then restoring the slope's topography by covering it with topsoil; constructing a masonry diamond-shaped grid structure for protection on the rock mine slope, planting native shrubs and grasses within the grid; installing an integrated water and fertilizer drip irrigation system on the rock mine slope; and finally, applying sprayed concrete or constructing slope supports to prevent soil erosion on the slope surface; wherein the altitude of the high-altitude area is >4000m. This ecological restoration method provides strong technical support for the ecological restoration of rock mine slopes in ecologically fragile high-altitude areas, and also provides important guarantees and references for ecological restoration work after mining in high-altitude regions.

The simple ladder stool comprises a main ladder body and a moving assembly, supporting column legs are arranged at the two ends of the lower portion of the main ladder body, stabilizing transverse rods are installed at the middle ends of the inner sides of the supporting column legs, and the moving assembly is arranged at the lower ends of the supporting column legs. And the moving assembly comprises a limiting frame, limiting sliding grooves, a servo motor, a lead screw, a movable sliding block and a bearing frame, the limiting sliding grooves are formed in the two sides of the interior of the limiting frame, the servo motor is installed at one end of the limiting frame, the lead screw is connected to the front end of the servo motor, meanwhile, the movable sliding block is arranged outside the lead screw, and the bearing frame is installed outside the movable sliding block. According to the simple ladder stool for operation of the nursery pond, front-back movement of the ladder stool in the using process can be achieved through the moving assembly, manual pushing is avoided, meanwhile, tobacco seedling thinning, fertilizer adding, seedling pulling, transplanting and other operations can be facilitated through the storage assembly, the working efficiency is improved, the manual labor intensity is reduced, the device is simple in structure, and the production cost can be greatly reduced.
