Spray slope greening method for mine vegetation recovery
The invention relates to the technical field of ecological restoration, and discloses a spray slope greening method for mine vegetation restoration, which comprises the following steps: 1) screening and treating mine wastes including tailings and slag; 2) mixing tailings, slag and organic matters to obtain a spray seeding substrate; (3) adding a nano silicon dioxide-based water-retaining agent into the spray-seeding substrate; 4) adding a biodegradable adhesive into the spray seeding matrix, wherein the adhesive is prepared from chitosan and sodium alginate; (5) spray-seeding the mixed material on the slope surface by using spray-seeding equipment; and (6) after spray-seeding is completed, non-woven fabric is covered to protect the spray-seeding matrix, and watering and fertilization maintenance are conducted on the slope surface. The mining wasteland vegetation restoration efficiency and stability are improved, meanwhile, the method adapts to various extreme environment conditions, the construction cost is reduced, and sustainable ecological restoration is promoted.
本发明涉及生态修复技术领域，公开了一种矿山植被恢复用喷坡绿化方法，包括以下步骤：1)矿山废弃物的筛选与处理，所述矿山废弃物包括尾矿和矿渣；2)将尾矿、矿渣与有机质混合，得到喷播基质；3)向所述喷播基质中添加纳米二氧化硅基保水剂；4)在喷播基质中加入生物降解粘合剂，所述粘合剂由壳聚糖和海藻酸钠制成；5)使用喷播设备将上述混合材料喷播到坡面上；6)喷播完成后，覆盖无纺布以保护喷播基质，并对坡面进行洒水和施肥养护。本发明提高了矿山废弃地植被恢复的效率和稳定性，同时适应多种极端环境条件，降低施工成本并促进可持续生态修复。
