【Objective】 Irrigation methods modulate soil water and root-induced activity thereby influencing gas emissions from soil. In this paper, we analyze the effects of different irrigation methods on greenhouse gas emissions from farmland and the associated underlying mechanisms. 【Method】 The analysis was based on meta-analysis. Experimental results published in journals included in CNKI and Web of Science were used in the analysis. A total of 37 papers with 176 datasets were analyzed to assess the variation in greenhouse gas emissions with irrigation methods, as well as the underlying mechanisms. 【Result】 Compared to drip irrigation, flood irrigation, furrow irrigation and subsurface drip irrigation did not show significant difference in CO2 emissions, while sprinkler irrigation significantly increased CO2 emissions (p |
