Wind erosion resisting method for bare soil in arid mining area
The invention discloses a method for resisting wind erosion of bare soil in an arid mining area, which comprises the following steps of: providing more energy substances, nutrient elements, electron acceptors required by a metabolic process, higher cation exchange capacity and water absorption and moisture retention for microorganisms by utilizing montmorillonite, and promoting the microorganisms to generate more calcium carbonate precipitates (MICP) through induction, so that the yield of the microorganisms is improved. The wind erosion resistance of the bare soil in the arid mining area is improved, and meanwhile, good environmental application performance is achieved. The specific method comprises the following steps: firstly adding montmorillonite into soil, then spraying a bacillus pasteurii bacterial liquid, calcium chloride and urea cementing liquid, firstly spraying the bacterial liquid, then spraying the cementing liquid, and curing at room temperature after cementing. The method is simple in process, low in cost, free of secondary pollution, high in consolidation layer thickness, high in calcium carbonate content, high in surface strength and high in critical wind starting speed, and has a good application prospect in the aspect of wind erosion resistance of bare soil in the arid mining area.
本申请公开一种干旱矿区裸土抗风蚀的方法，包括利用蒙脱石为微生物提供更多的能源物质、营养元素、代谢过程所需电子受体、以及较高的阳离子交换量与吸水保湿性，促进微生物诱导生成更多的碳酸钙沉淀(MICP)，提高干旱矿区裸土的抗风蚀能力，同时兼备良好的环境应用性能。具体方法为先将蒙脱石加到土里，随后喷洒巴氏芽孢杆菌菌液与氯化钙、尿素胶结液，先喷洒菌液，后喷洒胶结液，胶结后于室温下进行养护。本发明工艺简单、成本低、无二次污染，固结层厚度、碳酸钙含量、表面强度和临界起风速度较高，在干旱矿区裸土抗风蚀方面具有很好的应用前景。
