摘    要:试验于2006-2007年在河南省浚县农业科学研究所试验田进行,以传统平作为对照,研究了垄作栽培对夏玉米光合特性和产量的影响.结果表明,垄作提高了夏玉米光合速率Pn、叶片蒸腾速率Tr和气孔导度Gs,且其日变化均呈单峰曲线,12:00达到最大值,而细胞间隙二氧化碳浓度Gi有所降低,其日变化与Pn相反,呈倒抛物线型.垄作栽培夏玉米的最大光化学效率Fv/Fm和实际光化学效率φPSⅡ均有所增加.与平作相比,垄作后期叶面积衰减较慢,籽粒蜡熟期和成熟期垄作比平作叶面积指数分别高6.4%和3.7%,减少了漏光损失,垄作栽培延长了叶片功能期,促进光合产物的积累及向籽粒的转移,有利于后期玉米籽粒充实,千粒重显著高于平作,产量提高9.6%.

关 键 词:垄作  栽培方式  夏玉米  光合特性
