| 摘 要： | 为探讨不同灌溉方式对芝麻农艺性状、产量性状、冠层结构和光合特性的影响,2018年在河南省现代农业科技试验示范基地设置2个灌水模式（漫灌和滴灌）、选取2个基因型品种（郑太芝1号和郑黑芝1号）进行试验,结果表明：（1）与漫灌相比,滴灌条件下两品种的产量分别增加了13.58%和8.40%,经济系数增加了4.25%和4.29%;（2）与漫灌相比,滴灌显著改善了芝麻的冠层结构,在盛花中期影响最大,两品种叶面积指数（LAI）平均分别增加了2.61%和5.50%,冠层透光率（LTRC）降低了13.43%和23.22%;（3）与漫灌相比,滴灌条件下两品种净光合速率、SPAD值和叶绿素密度平均分别增加了3.60%和4.15%、2.99%和3.78%、8.24%和10.09%。

| Abstract: | To understand the effects of irrigation regimes on agronomic trait, yield traits, canopy structure and photosynthetic traits of sesame, we studied two sesame cultivars currently used in the production, Zhengtaizhi 1 (white) and Zhengheizhi 1 (black) under traditional irrigation (flooding irrigation) and water-saving irrigation (drip irrigation) in Henan Provincial Modern Agricultural Science and Technology Experiment Demonstration Base in 2018. The results showed: (1) Compared with flooding irrigation, the two cultivars under drip irrigation increased by 13.58% and 8.40% of yield and by 4.25% and 4.29% of economic coefficient, respectively. (2) Compared with flooding irrigation, the two cultivars under drip irrigation increased 2.61% and 5.50% in leaf area index (LAI) and decreased 13.43% and 23.22% in light transmission rate of canopy (LTRC). (3) Compared with flooding irrigation, the two cultivars under drip irrigation increased 3.60% and 4.15% in net photosynthetic rate, 2.99% and 3.78% in SPAD value and 8.24% and 10.09% in chlorophyll density. |
