Abstract: The present invention provides a slope repair method. The method includes pretreating a slope, so that an average roughness of the pretreated slope is not greater than ±8 cm to ±12 cm per linear meter; (2) hanging a hard protective mesh on the pretreated slope, where the distance between the hard protective mesh and the slope is 3-4 cm, and the hard protective mesh has an aperture size of 4-6 cm; and (3) spraying a loam-like matrix on the slope with the hard protective mesh hanged, where the loam-like matrix includes not less than 0.04/m2 of plant seeds; the plant seeds include tree seeds, shrub seeds and herb seeds with a mass ratio of (2.5-3.5):(4-6):(1.5-2.5). The method provided by the present invention effectively restores the mountain vegetation, and only needs 1-2 years of artificial maintenance after the restoration to form a cyclically stable ecosystem.

Abstract: A method for remedying sandy land by using a simulated loam substrate spray-seeding technology includes: first, carrying out a sand-fixing treatment to lay a metal mesh in sandy land, the metal mesh being fixed to the surface of the sandy land by a sand-fixing pile; second, spray-seeding a seed into the sandy land by simulated loam substrate spray-seeding; and finally, after spray-seeding, carrying out maintenance management, including adding a protective plate around the metal mesh, covering with a non-woven fabric, watering, fertilizing, reseeding, and post-monitoring. The present invention adopts a two-layer spray-seeding method, and rapidly simulates a loam substrate suitable for plant growth by bionics; the simulated loam substrate having good water retention capacity (conducive to a higher germination rate of seed), root development, microbial activity, nutrient transformation, and plant growth and development. With less investment and having a quick effect, large-scale sand control is provided.
