摘要： 为解决大宗矿泥、赤泥的无害化、资源化问题,以脱水矿泥、赤泥为研究对象,通过配施生物有机肥与复
合肥和盆栽种植玉米,并分析基质的理化性质、肥力状况、重金属等指标,探讨肥料-玉米协同作用对赤泥-矿泥土壤
化成土重构及其重金属的影响。结果显示,生物有机肥与复合肥配施显著促进了玉米生长,其株高和根长均明显高
于对照组;赤泥-矿泥土壤化处置使基质的容重从1. 1 g/ cm³ 降至0. 9 g/ cm³,孔隙度从60%提升至65%,物理结构得

降至7. 72、476. 9 μS/ cm,均符合相关标准;有机质和碱解氮含量提升至《全国第二次土壤普查养分分级》中的第五级,
有效磷、速效钾含量保持在三级、二级,较对照处理最高分别提升了0. 13、0. 08、6. 28 和2. 51 倍;玉米对赤泥-矿泥土

Abstract: In order to solve the problem of harmless and resource of bulk mineral sludge and red mud,regard dehydrated
slime and red mud as the research objects,combined application of bio-organic fertilizer compound fertilizer and potted corn
planting,the effect of fertilizer-maize synergy on the reconstruction of the soil formation of red mud and mine sludge and heavy
metals properties was explored by analyzing the physical and chemical properties,fertility status and heavy metals of the substrate.
The results showed that bio-organic fertiliser with compound fertiliser significantly promoted the growth of corn,resulting
in a significant increase in corn plant height and root length compared to the control;Substrate for the soilization disposal of red
mud and mine sludge matrix decreased from 1. 1 g/ cm3 to 0. 9 g/ cm3,and the porosity increased from 60% to 65%,physical
structure improved,microscopic spherical morphology,the formation of agglomerates and better connectivity. At 60 d of growth,
the pH and EC values of the substrate for the soilization disposal of red mud and mine sludge decreased to 7. 72 and 476. 9
μS/ cm,all in accordance with relevant standards;Organic matter and alkaline dissolved nitrogen contents were upgraded to the
fifth level in the Nutrient Classification of the Second National Soil Census,while effective phosphorus and quick-acting potassi
um contents were maintained at the third and second levels,compared with the control treatment of the highest were up 0. 13,
0. 08,6. 28 and 2. 51 times;The highest transfer and enrichment coefficients for Cr,As,Pb and Hg heavy metals of corn to the
substrate for the soilization disposal of red mud and mine sludge were 0. 78 and 0. 721,respectively,which were less than 1,indicating
that these heavy metals were not transferred and enriched to corn plants. Pearson correlation analysis showed that pH
significantly affected substrate phosphorus and potassium nutrient effectiveness and passivation of Cr,As,Pb and Hg heavy
metals. The results of this study can provide a reference for the ecological restoration of red mud and mineral mud soil.

Key words: red mud,mine sludge,soilization disposal,fertilizer,corn,mine ecological restoration
