Shading experiments were designed according to low light intensity problem caused by intercropping system of peanut with maize or wheat et al. Fenghua1 and Fenghua2 were adopted in the experiment of four light intensity levels (CK in which the plants were grown under natural light, 27% shading, 43% shading and 77% shading), which carried out at three growth stage using black sunshade net. And the three stages were seedling phase, pod-setting phase and pod-maturing phase. The aim of this study was to investigate the effects of low light on the photosynthetic characteristics, luminous energy distribute of PSⅡ, RuBPCase activitiy, plant morphogenesis, dry matter production, pod yield and quality of peanut at different stages, defined the relationship between dry matter accumulation and PAR, relationship of efficiency for solar energy utilization and PAR, and then set up the ...dry matter production and yield formation model on the basis of the experimental data.
