Abstract：To provide data support for the construction of efficient water-saving projects in farmland,promote the application of efficient water-saving technologies,and facilitate the efficient utilization of agricultural water resources,this study conducted a systematic survey on the current status of farmland irrigation in Changping district using the"one village,one map,one table"approach.The results showed that the area of farmland without irrigation conditions in the entire district was 2 553.5 hm2,accounting for 47.6％of the total farmland,where drought-tolerant crops such as spring corn and sweet potatoes were mainly grown.Among the farmland with irrigation conditions,pipe irrigation covered the largest area of 1 249.2 hm2,accounting for 23.3％of the total farmland,and was mainly applied to food crops.Next was micro-irrigation,covering 652.7 hm2,accounting for 12.2％of the total farmland,which was mainly used in facility agriculture.Sprinkler irrigation was the smallest,with an area of 413.0 hm2,accounting for 7.7％of the total farmland,and was mainly applied to food crops.There were problems such as a large area of dry land,low application rate of efficient water-saving technologies,and significant regional differences.To effectively improve the level of water-saving irrigation in farmland,measures such as developing rain-fed dryland farming according to local conditions,optimizing water supply,promoting the construction of efficient water-saving projects,and strengthening the popularization and management of water-saving technologies were proposed.These measures aimed to enhance the farmland irrigation level in Changping district and realize the green and low-carbon development of agriculture.
