摘 要 ：在试验大田，利用Li-Cor6200光合测定系统，以中秆大穗型品种鲁谷10号和矮秆紧凑型品种矮88为材料，初步研究了夏谷群体光合作用特性及其影响因素。结果表明，夏谷光合日变化呈单峰曲线，上午11时前后群体光合达最大值，其趋势与光照强度的变化基本吻合。两品种的群体光补偿点为180～190μE.m-2.s-1，鲁谷10号对高光强的利用

Abstract:The study was conducted in the experimental field during 1994～1995 to investigate the traits of canopy photosynthesis (CAP) and its influencing factors of summer-sowing millet. Two varieties of middle height Lugu No.10 and dwarf compact type Ai88 were tested using Li-Cor 6200 photosynthetic analysi
