摘　　要：为了探明中国北方地区地下滴灌(subsurface drip irrigation,SSDI)与地表滴灌(surface drip irrigation,SDI)节水增产效应的差异,该研究以SDI作为对照,采用Meta分析定量分析了不同条件下SSDI对作物产量和水分利用效率的影响。结果表明,与SDI相比,SSDI可使作物总体增产6.66%(P<0.05),水分利用效率提高9.34%(P<0.05),净效益增加6.94%(P<0.05);SSDI在西北和华北地区均能提高作物产量和水分利用效率;当年均降雨量不大于400 mm时,SSDI能显著提高作物产量;当土壤容重大于1.5 g/cm^(3),灌水施肥频率大于6次,滴灌带埋深为>15~25 cm,滴头流量介于>1.5~<2.5 L/h时,更有利于发挥SSDI优势,节水增产效果显著。研究可为中国北方地区SSDI的推广应用提供理论参考。This study was to assess the water-saving and yield-increasing differences between subsurface drip irrigation(SSDI)and surface drip irrigation(SDI)under various regional,crops,climatic,soil,field management,and drip irrigation technical factors.The data for this study were collected from literature published before November 4,2023.The selection criteria included:1)experiments conducted in fields in northern China;2)data collection limited to field experiments only;3)experiments involving both subsurface drip irrigation and surface drip irrigation treatments,with all other field trial conditions strictly consistent;4)the article must provide at least paired data on yield,water use efficiency,or economic benefits(net benefits),as well as sample size and standard deviation.A total of 223 sets of yield data,148 sets of water use efficiency data,and 31 sets of economic benefit(net benefit)data were obtained.The results showed that compared to SDI,SSDI could increase crop yield by 6.66%overall,improve water use efficiency by 9.34%and increase net benefits by 6.94%.When the average annual temperature was≥12℃and<12℃,SSDI could significantly increase crop yield by 11.05%and 5.69%,respectively,and significantly improve water use efficiency by 8.18%and 5.24%,respectively,but the inter-group differences were not significant.Compared to SDI,when the annual precipitation was≤200 mm and 200-400 mm,SSDI could significantly increase crop yield by 7.11%and 6.39%,respectively,and significantly improve water use efficiency by 7.29%and 3.89%,respectively.Compared to SDI,SSDI could significantly increase crop yield by 7.02%and 5.04%in the northwest and north China regions,respectively,and significantly improve water use efficiency by 8.57%and 10.46%,respectively,while the water-saving and yield-increasing effects were not significant in the northeast region.Compared to SDI,SSDI could significantly increase the yield of vegetables,and food crops by 9.7%and 5.14%,respectively,and significantly improve water use efficiency by 14.
