摘　　要：为了研究我国大陆不同作物类型、地域特征、气候条件以及土壤理化性质下,施用沼肥对作物产量的影响,该研究以施用化肥为对照组,以单施沼肥或沼肥配施化肥为试验组,根据已公开发表的129篇研究文章,共计431组数据,应用Meta分析法,定量分析沼肥的增产效应。结果表明:1)与施用化肥相比,施用沼肥会显著增加作物产量,增产率为8.88%。玉米、小麦、水稻、番茄、黄瓜产量分别增加9.87%,11.48%,3.84%,13.81%,12.72%;2)沼肥对西北地区的作物增产最显著,增产率为19.71%,其次为华北、东北和南方地区;3)在年降水量≤800 mm和年平均气温≤15℃的区域,沼肥增产效应较为明显,增产率分别为14.54%,12.39%;4)此外沼肥的增产效应也受到土壤理化性质的影响。该研究可为沼肥的推广应用提供参考。This study was to assess the effect of biogas fertilizer application on crop yield under conditions of different crops,districts,climates and soil physical and chemical properties,so as to provide references for the application of biogas fertilizer.The chemical fertilizer was taken as the control.A total of 129 papers about the effect of Chinese biogas fertilizer on crop yield were selected from the published papers,including 431 groups of data,Meta-analysis was applied to quantitatively analyze the yield increase effect of biogas fertilizer.The results showed that:1)the application of biogas fertilizer significantly increased crop yield by 8.88%,the yield of maize,wheat,rice,tomato and cucumber were increased by 9.87%,11.48%,3.84%,13.81% and 12.72%,respectively;2)the application of biogas fertilizer most significantly increased crop yield by 19.71% in Northwest China,followed by North,Northeast and South;3)in areas where the annual precipitation ≤800 mm and the annual average temperature ≤15℃,the effect of biogas fertilizer was more obvious,the yield increase rate was 14.54% and 12.39% respectively;4)in addition,the soil fertility also affected the effect of biogas fertilizer.
