This critical narrative review evaluates whether methane mitigation, water management, biochar amendment and yield resilience can be integrated into a coherent management strategy rather than treated as separate objectives. Literature published from 2000 to 3 July 2026 was considered, with earlier foundational evidence retained selectively where necessary. The strongest and most consistent evidence supports non-continuous flooding, particularly well-managed alternate wetting and drying (AWD), as the principal near-term field lever for lowering methane emissions and irrigation demand. Across recent meta-analyses, methane reductions are substantial, but nitrous oxide commonly increases, and yield responses depend strongly on drying severity, timing, soil properties, nitrogen supply and cultivar. Mild AWD is therefore better supported than severe drying as a production-compatible mitigation practice. Biochar can improve rice yield, nitrogen-use efficiency and soil carbon status while moderating greenhouse-gas emissions, but average methane mitigation is less consistent than that achieved through water management and is highly contingent on feedstock, pyrolysis conditions, application rate, soil properties and mineral nitrogen input. Direct factorial evidence combining AWD and biochar is still limited, although several multi-year field studies indicate that biochar can partly buffer nutrient losses, contaminant trade-offs and physiological constraints associated with soil drying. Evidence that AWD itself increases yield resilience to drought or heat is mechanistically plausible but remains cultivar- and experiment-specific; it should not yet be equated with proven long-term yield stability under climate extremes. The synthesis supports a hierarchical strategy in which water regime is the primary control, biochar and nitrogen management are context-dependent modifiers, and cultivar choice provides a resilience layer. Future progress requires multi-site factorial trials, explicit life-cycle accounting, multi-contaminant grain-safety assessment and measurement frameworks that verify water status, greenhouse gases and yield stability together.","水稻生产在气候智慧型农业中处于两难境地：淹水稻田土壤虽能支撑高产稳产，却为甲烷生成创造了有利条件，消耗大量灌溉用水，并可能改变籽粒中潜在有毒元素的生物有效性。本篇批判性叙事综述评估了甲烷减排、水分管理、生物炭施用与产量韧性能否整合为协调一致的管理策略，而非被当作彼此独立的目标。文献检索范围涵盖2000年至2026年7月3日发表的文献，必要时选择性保留了更早的基础性证据。最强且最一致的证据支持非连续淹水，尤其是管理良好的干湿交替（AWD），作为近期降低甲烷排放和灌溉需求的主要田间调控手段。近期多项荟萃分析显示，甲烷减排幅度可观，但氧化亚氮排放通常增加，且产量响应在很大程度上取决于晒田强度、时机、土壤性质、氮素供应和品种。因此，轻度AWD比重度晒田更适合作为与生产兼容的减排措施。生物炭可提高水稻产量、氮素利用效率和土壤碳储量，同时调节温室气体排放，但其平均甲烷减排效果不如水分管理稳定，且高度依赖于原料、热解条件、施用量、土壤性质和矿质氮投入。将AWD与生物炭相结合的直接析因证据仍然有限，尽管若干多年田间研究表明，生物炭可部分缓冲与土壤干燥相关的养分损失、污染物权衡和生理限制。AWD本身能否提高水稻对干旱或高温的产量韧性，其机制虽具合理性，但仍因品种和试验条件而异；目前尚不能将其等同于在气候极端条件下已获验证的长期产量稳定性。本综述支持一种分层策略，即以水分 regime 为首要调控手段，生物炭和氮素管理为情境依赖的调节因子，品种选择则提供韧性层。未来进展需要多地点析因试验、明确的生命周期核算、多污染物籽粒安全评估，以及能够同步验证水分状态、温室气体和产量稳定性的测量框架。",null,"Asian Research Journal of Agriculture","2026-09-09T00:00:00Z","论文",10,false,79,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":20,"relevant":21,"comment":22},18,22,13,8,1,"系统综述整合水分管理与生物炭的稻田甲烷减排路径，结论可靠但属学术综述，对产业实践有中长期参考价值。",[24],{"name":10,"url":6},[26,27,28,29,30,31],"智慧农业","水稻","生物炭","气候变化","节水灌溉","甲烷减排",0,"10.9734\u002Farja\u002F2026\u002Fv19i4912",{"doi":33,"openalex_id":35,"authors":36,"venue":10,"cited_by_count":32,"oa_url":6,"card":44,"direction":50,"ingested_from":51},"W7212070936",[37,40,42],{"name":38,"orcid":39},"Abhishek Sinha","https:\u002F\u002Forcid.org\u002F0000-0001-7220-0691",{"name":41,"orcid":9},"Sanchita Sarkar",{"name":43,"orcid":9},"Srinivasa Rao Meesala",{"tldr":45,"method":46,"finding":47,"direction":48,"opportunity":49},"综述评估水稻甲烷减排、水分管理、生物炭与产量韧性的整合策略，提出以水分管理为主的分层管理框架。","2000-2026年文献综述，整合meta分析与多年田间试验证据。","适度干湿交替是近期最可靠的减排增产手段，生物炭效果依赖条件，二者联合证据有限。","农业绿色发展与碳","亟需多点多因素试验，将水分、生物炭、氮肥与品种整合，并同步验证温室气体、产量稳定性和籽粒安全。","智慧农业 \u002F 农业物联网","openalex","2026-09-10T23:30:09.553677Z"]
