Meta分析滴灌灌溉量及品种对玉米产量和水分利用效率的影响
Effects of different irrigation amounts and maize varieties on the yield of maize and water use efficiency:A meta-analysis
摘要
Abstract
To investigate the effects of different irrigation amounts and varieties on maize yield and Water Use Efficiency(WUE)under drip irrigation conditions in northern China,we searched relevant literature published from January 2000 to June 2022 in CNKI,Wanfang Data Knowledge Service Platform,and Web of Science.A total of 74 publications were collected,from which 449 sets of yield data and 453 sets of WUE data were extracted.The collected data were then integrated.Taking 90％to 100％of the maximum irrigation amount as the control(W6),five different deficit irrigation treatments were set as follows:the maximum irrigation ≤50％(W1),＞50％-60％(W2),＞60％-70％(W3),＞70％-80％(W4),and＞80％-90％(W5).A meta-analysis method was employed to quantitatively analyze the changes in maize yield and WUE indicators among different irrigation amounts(W)and varieties under drip irrigation.The results indicated that:Compared to the control W6,the moderate deficit irrigation levels W4 and W5 significantly increased maize yield and WUE by 8.2％-15.2％and 11.7％-16.5％,respectively.When the irrigation was at W3,WUE was greatly improved while maintaining maize yield,with the effect values(SMD)=0.12 and=0.89(P＜0.05),respectively.However,at the irrigation levels W,and W2,both yield and WUE declined significantly compared to W6,with yield SMD=-0.22-0.83(P＜0.05)and WUE SMD=-0.41-0.04(P＜0.05),respectively.In addition,the effects of different maize varieties on yield and water use efficiency under different irrigation rates were different.Considering the yield and WUE,the light deficit irrigations W4 and W5 are recommended for the more water sensitive varieties such as'Simon 6','Hamco 858'and'Siena 1331'.For varieties with some drought resistance such as'Nonghua 101'and'Zhongdan 909',the medium deficit irrigation W3 is recommended;for varieties with strong drought resistance,such as'Junlong 1217'and'Xianyu 335',they can be irrigated at W,and W2 to maximize water productivity.In conclusion,it is suggested that a deficit irrigation pattern with 70％to 90％of the maximum irrigation can significantly improve the maize yield and water use efficiency.关键词
