Abstract: An experiment to measure the 3D PAR (Photosynthetic Active Radiation) distribution in maize canopy was designed. The following results have been achieved through 3D PAR analysis from this experiment. (1) The averaged PAR at different depths in maize canopy was decreased with the increase of accumula
