| 摘 要： | 果树种植土壤因其较高的施氮量,很可能是温室气体氧化亚氮(N2O)的重要排放源。本文重点阐述了果园系统土壤N2O排放监测的复杂性,在此基础上探讨了如何形成有效的监测系统,揭示了利用现有技术测定N2O的排放规律和减排技术效果,并对今后的研究工作提出了展望。今后应重点开展以下几方面的工作:制定不同种类果树种植下土壤N2O排放监测标准;研发果树种植系统不同施肥模式、不同灌溉模式、不同土壤管理制度下土壤N2O减排技术;加强与N2O排放相关联的土壤氮素转化过程及其关联微生物机制的研究;构建果树种植系统土壤氮素平衡和N2O排放模型。

| Abstract: | Fruit orchards are characterized by extremely high rates of N application, which raises serious concerns about the risk of high soil nitrous oxide(N2O)emissions, which is an important greenhouse gas. Here, we reviewed the complexity of soil N2O emission monitoring in fruit orchard systems, how to form effective monitoring systems, temporal and spatial variations, and potential mitigation strategies. In addition, future research directions were proposed. Future studies should focus on the following four areas:establishing monitoring standards for soil N2O emissions under different types of fruit orchards; developing fruit orchard-specific mitigation strategies for soil N2O emissions under varied fertilization, irrigation, and management models; exploring the relationship between soil N2O emissions and soil N transformation processes and their associated microbial mechanisms; and developing models of soil N balance and related N2O emissions in fruit orchards. |
