中文摘要：
文章综述了滴灌对农田N2O排放所产生的可能影响，并从灌水、施氮、作物覆盖以及土壤非生物因子等角度分别阐述了滴灌条件下这些因子对N2O排放的驱动效应与作用机制。总结了目前相关研究工作中的不足，指出未来需要加强：（1）不同区域不同气候特征下促使N20减排的水分和养分阈值范围研究；（2）不同驱动因子之间的综合效应研究；（3）多年滴灌长时间尺度的累积效应研究；（4）作物-土壤系统以及微生物驱动机制研究。
英文摘要：
The article summarized the possible effects of drip irrigation on N2O emissions from agricultural soil and it further described the effects of watering, fertilization, cover cropping and soil abiotie factors such as pH and soil quality to the N2O emissions and their possible influencing mechanisms, respectively. According to the review, the present researches are not sufficient and lacking the relative researches. In the future, it needs to strengthen the following researches ： （ 1 ） the water and nitrogen threshold in different places and different climate to reduce N2O emission. （2） The comprehensive effects of multiple factors on N2O emission. （3） The cumulative effects of long term periods. （4） The interactions between crops and soils system as well as the microbial mechanisms.
