Controlling agricultural carbon emissions contributes to achieving peak carbon emissions and carbon neutrality. However, as a conservation management practice of farmland, the impact of No-tillage management (NTM) on agricultural carbon emissions needs to be further discussed. The main purpose of this paper is to assess the direct effect and spatial spillover effect of NTM on agricultural carbon emissions, revealing the regulating mechanism of NTM on agricultural carbon emissions and the combined application of NTM. Results indicate that NTM reduces agricultural carbon emissions, which is significant in the central and western regions, along with the primary grain, corn, and rice production areas, as well as the northern regions of the Huai River. Furthermore, the spatial spillover analysis reveals that the implementation of NTM increases agricultural carbon emissions in neighboring regions, but financial support and cross-regional services can negatively regulate the relationship between NTM and space agricultural carbon emissions. This paper also finds that combining straw-returning technology and NTM reduces agricultural carbon emissions. Building a cross-regional coordination mechanism, an incentive mechanism, and innovating the conservation tillage model is essential for promoting the NTM and achieving agricultural carbon reduction.
控制农业碳排放有助于实现碳排放峰值和碳中和。然而，作为农田保护管理措施，免耕管理（NTM）对农业碳排放的影响仍需进一步讨论。本文的主要目的是评估 NTM 对农业碳排放的直接影响和空间溢出效应，揭示 NTM 对农业碳排放的调节机制以及 NTM 的综合应用。结果表明，NTM 减少了农业碳排放，在中部和西部地区、主要粮食产区、玉米产区和水稻产区以及淮河流域北部地区表现显著。此外，空间溢出分析表明，NTM 的实施会增加邻近地区的农业碳排放，但财政支持和跨区域服务可以负向调节 NTM 与空间农业碳排放之间的关系。本文还发现，秸秆还田技术与 NTM 结合可以减少农业碳排放。建立跨区域协调机制、激励机制和创新保护耕作模式对于推广 NTM 和实现农业碳减排至关重要。
