Abstract

Background: The rice-wheat rotation system (RWRS) is a predominant cropping pattern in mid-eastern China, playing a crucial role in ensuring food security. However, its intensive water and fertilizer inputs contribute significantly to greenhouse gas (GHG) emissions. With global climate warming, RWRS confronts the dual imperative of simultaneously enhancing productivity and eco-efficiency while significantly curtailing GHG emissions.

Results: Future warming climate under most global climate models (GCMs) had adverse impacts on yield, water-use efficiency (WUE), nitrogen-use efficiency (NUE) and GHG intensity (GHGI) of RWRS in the central and southern regions of mid-eastern China. Compared to traditional management (TM) with high water and nitrogen inputs, optimized water and nitrogen management (OM) - utilizing intermittent irrigation and a nitrogen application rate of 390 kg ha^-1 - can significantly enhance WUE and NUE while reducing GHGI, without compromising yield. Moreover, no tillage, as a conservation tillage (CT) practice could effectively mitigate the negative impacts of future climate change. The combination of OM and CT (OM + CT) can improve yield and eco-efficiency while reducing global warming potential. For RWRS with OM + CT, GHGI decreased by 45.6-60.9% under future climate scenarios compared to TM.

Conclusions: By using knowledge-based optimum management strategies, environmental risks can be reduced without sacrificing the yield of RWRS yield. This study demonstrates a useful approach with crop modelling to ensure yield for agriculture system at a lower environment cost, which can be adjusted and applied in other farming systems and regions. © 2025 Society of Chemical Industry.

未来气候变化和管理措施对水稻-小麦轮作系统产量、生态效率和全球变暖潜力的影响

背景：稻麦轮作制度（RWRS）是中国中东部地区的主要种植模式，在保障粮食安全方面发挥着至关重要的作用。然而，其密集的水和肥料投入对温室气体（GHG）排放有很大贡献。随着全球气候变暖，RWRS面临着在显著减少温室气体排放的同时提高生产力和生态效率的双重要求。结果：在大多数全球气候模式（GCMs）下，未来气候变暖对中国中东部中南部地区水源地的产量、水分利用效率（WUE）、氮利用效率（NUE）和温室气体强度（GHGI）产生不利影响。与高水氮投入的传统管理（TM）相比，优化的水氮管理（OM）——利用间歇灌溉和390 kg hm -1施氮量——在不影响产量的情况下，显著提高了水分利用效率和氮肥利用效率，同时降低了GHGI。此外，免耕作为保护性耕作（CT）可以有效缓解未来气候变化的负面影响。OM和CT的结合（OM + CT）可以提高产量和生态效率，同时降低全球变暖的潜力。与TM相比，具有OM + CT的RWRS在未来气候情景下GHGI降低了45.6% ~ 60.9%。结论：采用基于知识的优化管理策略，可以在不牺牲水源地产量的前提下降低环境风险。该研究展示了一种有效的作物建模方法，以较低的环境成本确保农业系统的产量，该方法可以调整并应用于其他农业系统和地区。©2025化学工业协会。
