Simulation of the effects of soil water condition on winter wheat growth

Based on the crop growth model MACROS (L1D), a dynamic coupling model for crop growth, water and balance in field was established. The model includes three submodels: cropgrowth water transmission in SPAC system and coupling relationship between crop growth and soil water conditions. This paper focus on the discussions of the coupling relationship between soil water condition and crop growth. Comparing with the field experiment, the simulation results of winter wheat growth and the sensitivities of some parameters for the coupling relations in the model were analyzed. By using this model, the effects of soil water conditions on winter wheat production in rainy region of southern China were simulated and some methods to improve soil conditions for wheat production were discussed.
