| 为探究灌溉方式、灌溉水平和品种对玉米水分利用效率及产量的定量影响，基于中国知网及Web of Science，以“玉米”、“滴灌”、“水分利用效率/产量”等为主题检索词，检索到2000-01-01—2020-12-31发表的110篇文献，并根据已定筛选标准，最终纳入21篇文献的94组相关数据进行Meta-Analysis。结果表明:1)以灌溉量为40%~60%的作物需水量(ETc)为对照，与60%~80%、100%~120%和120%~140%的ETc相比，灌溉量为80%~100% ETc时，玉米水分利用效率的效应值最高，标准均值差SMD=2.83(P<0.05)，产量的效应值也较高，SMD=1.70(P>0.05)；2)灌溉量在80%~100% ETc的水平下，以滴灌为对照，畦灌、沟灌和漫灌的玉米水分利用效率的合并效应值SMD=-4.55(P<0.05)，产量的合并效应值SMD=-1.34(P<0.05)；3)灌溉量在80%~100% ETc的水平下，以‘郑单958’为对照，与‘西蒙6号’、‘沈单10号’、‘秋乐126’和‘农华101’相比，种植‘京科958’的玉米水分利用效率的效应值最高，SMD=4.53(P<0.05)，产量的效应值也最高，SMD=6.70(P<0.05)。因此，建议在灌溉区域采用滴灌灌溉方式，能够增产节水。水分利用效率能提高45.5%，产量能提高13.4%。同时使滴灌水平控制在80%~100% ETc下，节水增产的效果更优。 |

| Abstract: |
| To investigate the quantitative effects of irrigation methods, irrigation levels and crop varieties on the water use efficiency and yield of maize in China, 110 papers published from 2000-01-01 to 2020-12-31 were retrieved by using “maize”, “drip irrigation” and “water use efficiency/yield” as subject search terms on CNKI and Web of Science. According to the established screening criteria, 94 groups of relevant data from 21 papers were included for Meta-Analysis. The results showed that: 1)Using 40%-60% ETc(crop water requirement)as control, compared with 60%-80% ETc, 100%-120% ETc and 120%-140% ETc, the irrigation amount of 80%-100% ETc had the highest effect value of water use efficiency with SMD=2. 83(P<0. 05). The effect value of yield was also higher with SMD=1. 70(P>0. 05). 2)Under 80%-100% ETc, using drip irrigation as control, the combined effect of water use efficiency under border irrigation, furrow irrigation and flood irrigation was SMD=-4. 55(P<0. 05), and the combined effect of yield was SMD=-1. 34(P<0. 05). 3)Under 80%-100% ETc and using‘Zhengdan 958'as control, compared with ‘Ximeng 6', ‘Shendan 10', ‘Qiule 126'and ‘Nonghua 101', ‘Jingke 958'had the highest effect value of water use efficiency with SMD=4. 53(P<0. 05). The effect value of yield was also the highest with SMD=6. 70(P<0. 05). Therefore, application of drip irrigation in the irrigation areas can increase production and save water. The water use efficiency(WUE)and yield increased by 45. 5% and 13. 4%, respectively. At the same time, when the drip irrigation level is controlled at 80%-100% ETc, the effect of water-saving and yield increase is better. |
