Abstract

Abstract:

Although exogenous carbon input is known to enhance carbon sequestration potential in paddy soils, the mechanisms by which its chemical structure influences soil carbon emissions and organic carbon (SOC) fractions remain unclear. In this study, we conducted an anaerobic slurry incubation experiment to compare the effects of adding non-structural carbon sources (glucose, starch) versus a structural carbon source (cellulose) on CO₂ and CH₄ emissions, as well as on labile (LOC) and recalcitrant (ROC) organic carbon, particulate organic carbon (POC) and mineral-associated organic carbon (MAOC). Results showed that SOC content in soils treated with exogenously added glucose, starch, and cellulose decreased by 1.33%, showed no significant effect, and increased by 3.24%, respectively, compared with the control. While all exogenous carbon additions significantly increased cumulative CO₂ emissions by 69.71%-73.35% and CH₄ emissions by 105.17%-117.56%, there were no significant differences among the treatments. LOC was positively correlated with SOC (r=0.711, p=0.010) and was significantly lower in glucose and starch treatments than in the cellulose treatment. Although ROC content did not differ significantly among exogenous carbon treatments, the w_(ROC)/w_(LOC) ratio was significantly higher in glucose and starch treatments than in the cellulose treatment, indicating that non-structural carbon inputs enhance the oxidative stability of SOC. Conversely, MAOC content was significantly lower in glucose and starch treatments than in the cellulose treatment, while dissolved organic carbon (DOC) and ferrous iron (Fe²⁺) concentrations showed opposite trends. This suggests that non-structural carbon inputs promote the reductive dissolution of Fe(Ⅲ) minerals, thereby weakening the mineral protection of SOC. Collectively, these findings demonstrate that the chemical structure of exogenous carbon regulates paddy SOC stocks primarily by modulating SOC oxidative stability and mineral-mediated protection mechanisms.

Key words: paddy soil, chemical structure of exogenous carbon, soil carbon emissions, soil organic carbon stability, mineral-associated carbon sequestration

摘要：

外源有机碳添加虽能提升稻田固碳潜力，但其化学结构差异如何影响土壤碳排放与有机碳组分仍不清楚。该研究通过厌氧泥浆培养试验，比较非结构性碳源（葡萄糖、淀粉）和结构性碳源（纤维素）添加下稻田土壤二氧化碳（CO₂）、甲烷（CH₄）、活性（LOC）和惰性（ROC）有机碳、颗粒态（POC）和矿物结合态有机碳（MAOC）的变化。结果显示，外源添加葡萄糖、淀粉和纤维素处理的土壤有机碳（SOC）质量分数与对照组相比分别降低1.33%、无显著影响和增加3.24%。外源碳添加增加了69.71%－73.35% CO₂和105.17%－117.56% CH₄的累积排放量，但各处理无显著差异。LOC与SOC呈显著正相关（r=0.711，p=0.010），且与纤维素添加处理相比，其在葡萄糖和淀粉添加处理中的质量分数较低。ROC质量分数在外源碳添加处理间无显著差异，但葡萄糖和淀粉添加处理的w_(ROC)/w_(LOC)显著高于纤维素处理，证明非结构性碳源添加有助于SOC氧化稳定性的提升；葡萄糖和淀粉添加处理的MAOC质量分数显著低于纤维素添加处理，而可溶性有机碳和亚铁离子质量分数则呈现出相反趋势，证明非结构性碳源添加促使含铁（Ⅲ）矿物发生还原溶解，导致SOC的矿物保护作用减弱。以上结果反映了外源碳化学结构主要通过影响SOC氧化稳定性和矿物保护作用调控稻田有机碳库储量。
