However, no clear pattern of CA's effect on greenhouse gas emissions exist, due to complex and interactive processes from CA's three main principles including appropriate fertilizer use as the fourth proposed principle of CA. Objective A comprehensive literature search was conducted to review evidence on the effect of CA's three main principles (reduced tillage, mulching, crop diversification) including appropriate fertilizer management on greenhouse gas (nitrous oxide–N 2 O, carbon dioxide–CO 2 , methane–CH 4 ) emissions. Methods We reviewed 422 out of 3452 publications to assess the relative strength of evidence on effects of reduced tillage, mulching and fertilizer management on greenhouse gas emissions, with an in-depth multi-study synthesis on crop rotation and experimental characteristics. Control treatments included conventional tillage, zero mulch, monocropping and standard mineral nitrogen (N) fertilizer application. Results and conclusions There was good (73%) and some (46%) evidence that reduced tillage practices reduce CO 2 and N 2 O emissions, respectively. There was some evidence that mulching increases N 2 O (46%) and CO 2 (55%) emissions while the effects of different fertilizer management strategies on greenhouse gas emissions were mixed. The multi-study analysis showed an association of nitrogen fertilizer category, N fertilizer rate and overall rotation type with CH 4 emission. However, the CH 4 distribution was highly inconsistent. Overall, continuous legume-legume rotation was associated with decreases in CO 2 compared to continuous cereal-cereal rotations. The cereal-cereal rotation up to and including the current crop was associated with an increase in CO 2 emission relative to a monocrop. Nitrous oxide was associated with the N fertilizer application rate with the medium N fertilizer rate (102–175 kg N ha −1 ) associated with increases in N 2 O compared to the zero N control. Significance Our study highlights the effect of CA's three main principles and appropriate fertilizer use on greenhouse gas emissions under different cropping systems and agroecological regions, and the need for standardised reporting to ensure continued importance of field experiments, particularly long-term experiments, in providing empirical evidence on impacts of agronomic practices on global environmental change.","背景 保护性农业（CA）因其在减缓气候变化等方面的潜在效益，在过去十年中受到关注。然而，由于保护性农业三项主要原则及其作为第四项拟议原则的合理施肥之间复杂的交互过程，保护性农业对温室气体排放的影响尚无明确规律。目的 本研究进行了全面的文献检索，以综述保护性农业三项主要原则（减少耕作、覆盖、作物多样化）及合理施肥管理对温室气体（一氧化二氮–N₂O、二氧化碳–CO₂、甲烷–CH₄）排放影响的证据。方法 我们从3452篇文献中筛选出422篇进行综述，以评估减少耕作、覆盖和施肥管理对温室气体排放影响的证据相对强度，并对作物轮作和试验特征进行了深入的多研究综合分析。对照处理包括常规耕作、无覆盖、单作和标准矿质氮（N）肥施用。结果与结论 有良好证据（73%）和一些证据（46%）表明，减少耕作措施分别降低CO₂和N₂O排放。有一些证据表明，覆盖增加了N₂O（46%）和CO₂（55%）排放，而不同施肥管理策略对温室气体排放的影响则好坏参半。多研究分析显示，氮肥类别、氮肥施用量和总体轮作类型与CH₄排放存在关联。然而，CH₄分布高度不一致。总体而言，与连续谷类-谷类轮作相比，连续豆类-豆类轮作与CO₂排放减少相关。与单作相比，截至并包括当前作物的谷类-谷类轮作与CO₂排放增加相关。一氧化二氮与氮肥施用量相关，中等氮肥施用量（102–175 kg N ha⁻¹）与零氮对照相比增加了N₂O排放。意义 本研究强调了保护性农业三项主要原则及合理施肥在不同种植制度和农业生态区域下对温室气体排放的影响，并指出需要标准化报告，以确保田间试验，特别是长期试验，在提供农艺措施对全球环境变化影响的实证证据方面持续发挥重要作用。",null,"Agricultural Systems","2026-09-09T00:00:00Z","论文",10,false,81,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":20,"relevant":21,"comment":22},18,22,14,9,1,"基于3452篇文献筛选422篇的保护性农业温室气体效应综述，方法扎实、结论具参考价值，但属学术综述而非产业级突破，适合作为专业精选。",[24],{"name":10,"url":6},[26,27,28,29,30],"温室气体","保护性农业","农业减排","施肥管理","免耕覆盖",0,"10.1016\u002Fj.agsy.2026.104909",{"doi":32,"openalex_id":34,"authors":35,"venue":10,"cited_by_count":31,"oa_url":6,"card":86,"direction":90,"ingested_from":92},"W7212036648",[36,38,41,43,45,48,51,54,56,58,61,63,66,68,70,72,74,77,80,83],{"name":37,"orcid":9},"Muneta G.
