The 3D rice canopy photosynthesis model (3dCAP) combines three-dimensional canopy architecture, canopy vertical nitrogen distribution, a ray-tracing algorithm, and a leaf photosynthesis model. 3dCAP predicted daily canopy radiation use efficiency (RUE) for different nitrogen treatments of a given rice cultivar under different weather conditions. 3dCAP was used to explore the influence of three canopy architectural parameters—tiller number, tiller angle and leaf angle—on canopy RUE. Under different weather conditions and different nitrogen treatments, canopy architecture optimized by manipulating these parameters can increase daily net canopy photosynthetic CO2 uptake by 10–52%. Overall, this model has potential to be used in rice ideotype design for improved canopy RUE.
