| 为探究肥料协同旱稻种植对赤泥矿泥土壤化处置成土的土壤重构与生态重塑，在大田设置4种不同施肥量的赤泥矿泥土壤化处置成土进行旱稻种植。结果表明：各施肥处理旱稻农艺性状与正常大田相近，平均产量达8 282.7 kg·hm-2；肥料-旱稻协同作用能有效改善土壤理化性质，其中土壤平均含盐量降低861.62 μS·cm-1，孔隙度提升8.88个百分点，土壤铵态氮、有效磷及速效钾养分含量分别提升48.9%、71.2%、6.13%，达到农耕的适宜水平；土壤pH、EC、有机质及铵态氮对微生物群落结构和根际代谢物有显著影响，各施肥处理土壤微生态环境有明显差异，其中施用复合肥600 kg·hm-2+生物有机肥1 500 kg·hm-2处理土壤的旱稻农艺性状最好，大粒径（>2 mm）土壤团聚体含量最高且稳定性较好，土壤中华单细胞菌属、诺尔氏菌属等相对丰度占比较大，其分泌的植物激素、有机酸和萜类物质的高表达量，对赤泥矿泥土壤演化、微生态重构及作物生长有积极促进作用。 |

| In order to investigate the soil reconstruction and ecological remodeling of red mud mineralized soil disposal soil by fertilizer synergistic upland rice planting, four different fertilizer application rates of red mud mineralized soil disposal soil were set up for upland rice planting in the field. The results showed that the agronomic traits of upland rice in each fertilizer treatment were similar to those of normal field, and the average yield reached 8 282.7 kg·hm-2; the fertilizer- upland rice synergistic effect could effectively improve the soil physicochemical properties, in which the average soil salinity was reduced by 861.62 μS · cm-1, the porosity was increased by 8.88 percentage points, and the nutrient contents of soil ammonium nitrogen, effective phosphorus, and quick-acting potassium were increased by 48.9%, 71.2%, 6.13% to reach the appropriate level for farming; soil pH, EC, organic matter and ammonium nitrogen had significant effects on microbial community structure and inter-root metabolites, and there were obvious differences in soil microbiological environments of the fertilizer treatments, among which the composite fertilizer 600 kg·hm-2+bio-organic fertilizer 1 500 kg·hm-2 treatment had the best agronomic traits for upland rice, and the large-grain-size（>2 mm）soil aggregates with the highest content and better stability, the relative abundance of Sinomonas and Knoellia spp. in the soil accounted for a large proportion of the high expression of phytohormones, organic acids, and terpenoids secreted by them, which positively contributed to the evolution, microecological reconfiguration, and crop growth of the terracotta mineral mud soil. |
