摘 要 ：在产量为7.0～7.7 t/hm2高产条件下研究了中熟、疏枝、直立、大果花生品种冠层的某些生理特征，结果表明，在花生生育中期，冠层2/3以上叶层为群体主要吸光层，LAI和LIR分别约占各自总量的1/2和4/5；花生消光系数（k）为0.82～0.87，适宜最高LAI为5.5；始花后，群体光合作用日变化呈单峰曲线（晴日无云），高峰出现在10:00～1

Abstract:Peanut varieties characterized by few branches, medium duration of growth, erect growing habit, and big pods were used to study some physiological characteristics related to their canopy morphology under yields of 7.0－7.7 t/hm2 condition. Results showed: (1) The upper 1/3 of the canopy, during the
