| 摘 要： | 以郑单958、浚单20为试验材料，设定60 000株/hm2、75 000株/hm2两个密度，研究夏玉米产量与产量构成因素、干物质生产、叶面积指数发展动态、光合作用等，探讨喷施Cabrio和Opera试剂对夏玉米植株发育及产量的影响。结果表明，喷施药剂Cabrio和Opera后玉米产量增加，浚单20较对照分别增产6.7%和4.0%；郑单958较对照分别增产5.3%和4.2%。喷施药剂Cabrio和Opera的处理生育后期下部叶片衰老缓慢，吐丝期至成熟期LAI下降幅度较小，单株干物重和单位面积干物质积累增强，光合性能增强，光合速率提高。

| Abstract: | Zhengdan958 and Xundan20 were planted at 60 000 and 75 000 plants/ha, respectively, the effects of Cabrio and Opera on plant development were studied by testing yield and yield component, dry matter production, leaf area index development. The results showed that maize production was increased after spraying Cabrio and Opera, Jundan20 increased 6.7% and 4.0%, respectively than CK; Zhengdan 958 were 5.3% and 4.2%. Sparing Cabrio and Opera delayed leaf senescence in plant bottom during the late growing stage, slow down the decline of LAI from silking stage to maturity stage, improved dry weight accumulation and photosynthetic capability, therefore yield was increased compared with control. |
