摘要： 高产夏玉米群体光合速率在整个生育期的变化呈单峰型曲线,开花期达最大值.紧凑型品种在适宜高密度下具有较高的群体光合速率,易获高产,平展型品种在适宜低密度下,大喇叭口期上部叶＞上部叶下部叶,平展型品种上部叶＞中部叶＞下部叶.高产群体光合最适叶面积指数紧凑型品种6-7,平展型品种4-5.玉米开花后的群体光合速率与生物产

Abstract: The present study was carried out during 1989-1990 to investigate the relationship between the canopy apparent photosynthesis(CAP) rate and grainyield of two high-yielding summer corn cultivars at five different sowing densities. The results are as follows. The CAP rate of summer corn showed a
