摘　　要：我国尾矿堆存量大、堆存速率快、利用率低,提升尾矿的大规模综合利用水平迫在眉睫。尾矿中含有多种矿物成分和养分,具有制备水稻育秧基质的潜力。为评价利用尾矿制备水稻育秧基质的综合效益与市场前景,本文从市场需求量、生态效益、经济效益、社会效益与市场前景5个角度进行了分析,结果表明:我国水稻育秧基质年需求量约为7.3亿t;生产水稻育秧基质的年碳排放量为5.66亿tCO_(2),若利用尾矿制备水稻育秧基质,每年的碳减排潜力可达1.50亿tCO_(2);同时,还可以节省约73%的原辅材料成本,具有显著的价格优势,市场前景广阔。利用尾矿制备水稻育秧基质,不仅有助于解决尾矿堆积带来的环境问题,还能为农业生产提供新的原材料来源,有助于农业的绿色可持续发展。It is urgent to improve the large-scale comprehensive utilization level of tailings due to the large stock,fast storage rate and low utilization rate of tailings in China.The tailings contain a variety of mineral components and nutrients,which have the potential to prepare rice seedling substrate.To evaluate the comprehensive benefits and market prospects of using tailings to prepare rice seedling substrate,this article analyzed from five perspectives:market demand,ecological benefits,economic benefits,social benefits,and market prospects.The results showe that the annual demand of rice seedling substrate in China is about 730 million tons.The annual carbon emission of rice seedling substrate is 566 million tons of CO_(2).If the tailings are used to prepare rice seedling substrate,the annual carbon emission reduction potential can reach 150 million tons of CO_(2).At the same time,it can also save about 73%of the cost of raw and auxiliary materials,which has a significant price advantage and a broad market prospect.The use of tailings to prepare rice seedling substrate not only helps to solve the environmental problems caused by tailings accumulation,but also provides a new source of raw materials for agricultural production and contributes to the green and sustainable development of agriculture.
