摘要

摘要: 为探究黑曲霉孢子粉与新型保水材料SJP对铁尾矿渣的协同改良效应。本研究选取阿吾拉勒铁矿带为研究对象，采用室内盆栽试验测定植物生长指标、土壤理化性质、土壤酶活性及土壤微生物群落特征，并结合主成分分析计算土壤综合得分确定最优改良配比。研究表明，改良组显著促进苜蓿生长，株高提高166.67%；同时改善土壤养分循环，土壤含水率提升203.61%、土壤养分提升87.92%～1935.67%；土壤酶活性提升186.74%～1532.24%；土壤根际微生物群落结构改善，且微生物功能预测结果表明，糖酵解支路、氨基酸生物合成等基础代谢功能显著富集；确定最优改良方案为：渣土比1:0、SJP浓度1%、孢子粉添加量2.0g。本研究为新疆铁尾矿生态修复提供了技术支撑，助力矿产资源绿色开发与生态环境保护。

Abstract: To explore the effects of Aspergillus niger spore powder and the new water-retaining material SJP on iron tailings, this study selected the Awulale iron ore belt as the research site. An indoor pot experiment was conducted to investigate plant growth indicators, soil physical and chemical properties, soil enzyme activity and soil microbial community characteristics. The principal component analysis was combined to calculate the comprehensive soil score to determine the optimal improvement ratio. The results showed that the improvement group significantly promoted the growth of alfalfa, with the plant height increasing by 166.67%. Meanwhile, it improved the soil nutrient cycle, with the soil moisture content increasing by 203.61% and soil nutrients increasing by 87.92% to 1935.67%. Soil enzyme activity increased by 186.74% to 1532.24%. The soil rhizosphere microbial community structure was improved, and the microbial function prediction results indicated that the basic metabolic functions such as glycolysis and amino acid biosynthesis were significantly enriched following soil improvement. The optimal improvement scheme was determined as: tailings-soil ratio 1:0, SJP concentration 1%, and spore powder addition 2.0g. This study provides technical support for the ecological restoration of iron tailings in Xinjiang, and contributes to the green development of mineral resources and ecological environment protection.
