METHOD FOR REMEDYING SANDY LAND BY USING SIMULATED LOAM SUBSTRATE SPRAY-SEEDING TECHNOLOGY

摘要

The present invention discloses a method for remedying sandy land by using a simulated loam substrate spray-seeding technology. The method includes the following steps: first, carrying out a simple 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 means of simulated loam substrate spray-seeding; and finally, when the spray-seeding is completed, 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 method for remedying sandy land by using a simulated loam substrate spray-seeding technology provided by the present invention adopts a two-layer spray-seeding method, and rapidly simulates a simulated loam substrate suitable for plant growth in natural world by bionics; the simulated loam substrate has a good water retention capacity, which is conducive to a higher germination rate of a seed, root development, a microbial activity, nutrient transformation, and plant growth and development; and with less investment and a quick effect, the method is suitable for large-scale sand control.
