| 摘 要： | N2O是大气中对温室效应和大气臭氧层损耗有重要影响的微量气体.农田气体排放是大气中N2O的重要来源.灌溉方式能从多个方面影响农田N2O的排放.因此,追踪灌溉方式对农田N2O排放影响的研究进展,不仅可以为我国农田N2O排放机理的进一步研究提供参考,而且对我国发展低碳环保农业具有十分重要的意义.该研究简要地探讨了淹灌、无水层灌溉、天然降雨3种灌溉方式对农田土壤N2O排放的影响,并对该领域的研究做出展望. |

| Abstract: | N2O is a trace gas in the atmosphere which plays an important role in the greenhouse effect and atmospheric ozone depletion.The farm is an important source of N2O.Irrigation methods can influence farmland N2O emissions from several aspects.So tracking the research progress of the effect of irrigation on farmland N2O emissions,not only provide the reference for further research of the mechanism of N2O emissions in farmland,but also has very important significance for China's low carbon environmental protection agriculture.The effects of three different irrigation methods including basin irrigation,irrigation without water layer and natural rainfall condition on soil N2O emission were discussed,the research in the field was forecasted. |
| Keywords: | Irrigation methods N2O Farmland Emission |
