Biochar modulates microbial- and plant-derived carbon distribution in soil aggregates: Enhancing organic carbon sequestration in paddy fields across different water management practices

These data are the original data of the observation of soil organic carbon (SOC), soil aggregate distribution, and plant and microbial derived carbon (C). These data advance our understanding of the mechanisms by which biochar (B) amendment increases SOC sequestration and provide guidance for optimizing C management strategies in paddy fields across different water management practices (FI (flooded irrigation) and CI (controlled irrigation)).本数据集包含土壤有机碳（soil organic carbon）、土壤团聚体分布、植物与微生物源碳（C）的原位观测原始数据。本数据集有助于深化对生物炭（biochar）还田提升土壤有机碳固存作用机制的理解，并可为优化不同水分管理模式（淹水灌溉（FI, flooded irrigation）与控制性灌溉（CI, controlled irrigation））下稻田的碳管理策略提供指导。
