| Abstract: | EPIC (Erosion-Productivity Impact Calculator) is a world famous dynamic model that can be used to assess the effect of management strategies on farmland soil and water resources and crop productivity. The math equations to simulate crop growth,yield formation and environment stress in the EPIC model were briefly introduced in this paper. This is good for understanding basic simulating principles and processes of crop growth and yield formation in the EPIC model, and it can be used as reference for crop growth simulation and crop productivity quantitative assessment research. Finally, the further improvements in the EPIC model were pointed out. |
| Keywords: | EPIC model crop growth yield formation simulation equation |
