NH3是导致灰霾的重要因子,是酸雨和空气质量恶化等严重生态失衡环境问题的元凶之一.该研究针对当前农田化肥过量施用导致NH3排放强度大的焦点问题,通过SCI期刊网和中国科学引文数据库检索农田NH3排放相关文献,归纳和总结农田NH3排放影响因素和减排技术研究进展,今后农田NH3排放和减排技术主攻方向需要加强不同土壤环境、不同作物类型野外原位观测,明确肥料施用时期、施用比例、温度和有机肥管理对农田NH3排放的影响规律.研究结果有助于理清农田NH3排放影响因子,为减缓农田NH3排放研究提供理论指导和支撑.%NH3 is one of the leading causes of grey haze, and one of the main causes of serious ecological im-balances that result in environmental problems such as acid rain and air quality deterioration. At present, excessive fertilizer application greatly intensifies NH3 emissions intensity on farmland. In order to understand status and achievements of research on farmland NH3 emissions, the literature of farmland NH3 emission-related studies was retrieved from SCI journals and the Chinese science citation database. These are summarized with respect to the research progress on NH3 emission factors and emission reduction technologies. The future research direction of field NH3 emission and emission reduction technology need to strengthen the field observation on different soil en-vironment and crop types, and understand the effect of NH3 emission on fertilizer application period and the pro-portion, temperature and organic fertilizer management in farmland mainly. The research results can provide more information about the factors that influence NH3 emissions. This study offers theoretical guidance and support di-rected at mitigating farmland NH3 emissions in the future.
