【 摘 要 】

N2O is an important greenhouse gas in the atmosphere. Agricultural production is the largest source of N2O emissions. The influencing factors of N2O emission from farmland ecosystem, such as soil moisture, soil temperature, soil oxidation-reduction potential, pH of soil, fertilization management and soil texture are summarized, which are closely related to irrigation management. The soil moisture content of drip irrigation, sprinkler irrigation and other water-saving irrigation methods is different. The research on N2O emission from the world's water-saving irrigation mode has great potential for reducing greenhouse gas emissions. Future work on N2O emissions should carry out the studies on the regulation of greenhouse gas emission by water saving irrigation in different ecological conditions.
