This review paper synthesizes the current understanding of greenhouse gas (GHG) emissions from field cropping systems. It examines the key factors influencing GHG emissions, including crop type, management practices, and soil conditions. The review highlights the variability in GHG emissions across different cropping systems. Conventional tillage systems generally emit higher levels of carbon dioxide (CO) and nitrous oxide (NO) than no-till or reduced tillage systems. Crop rotation, cover cropping, and residue management can significantly reduce GHG emissions by improving soil carbon sequestration and reducing nitrogen fertilizer requirements. The paper also discusses the challenges and opportunities for mitigating GHG emissions in field cropping systems. Precision agriculture techniques, such as variable rate application of fertilizers and water, can optimize crop production while minimizing environmental impacts. Agroforestry systems, which integrate trees and crops, offer the potential for carbon sequestration and reducing NO emissions. This review provides insights into the latest research on GHG emissions from field cropping systems and identifies areas for further study. It emphasizes the importance of adopting sustainable management practices to reduce GHG emissions and enhance the environmental sustainability of agricultural systems.
这篇综述论文综合了当前对大田种植系统温室气体（GHG）排放的理解。它研究了影响温室气体排放的关键因素，包括作物类型、管理措施和土壤条件。该综述强调了不同种植系统间温室气体排放的变异性。传统耕作系统通常比免耕或减少耕作系统排放更高水平的二氧化碳（CO）和一氧化二氮（N₂O）。作物轮作、覆盖作物种植和残茬管理可通过改善土壤碳固存和减少氮肥需求显著降低温室气体排放。本文还讨论了大田种植系统中减少温室气体排放的挑战和机遇。精准农业技术，如肥料和水的变量施用，可在优化作物生产的同时将环境影响降至最低。将树木与作物相结合的农林业系统具有碳固存和减少一氧化二氮排放的潜力。这篇综述提供了对大田种植系统温室气体排放最新研究的见解，并确定了进一步研究的领域。它强调了采用可持续管理措施以减少温室气体排放和增强农业系统环境可持续性的重要性。
