Abstract

Effects of soil water on crop growth and yield are performed on the changes of crop growing conditions and biomass growth. In this paper, long-term field experiment data at Zhengzhou Experiment Station were used to statistically analyze the relationships between crop growing conditions and biomass growth at current stage and soil water at previous stage. And the relationships between soil water and yield were also set up. Subsequently, optimum soil water and drought indexes were determined for different growth stages of winter wheat. All these results lay the foundation for dynamic evaluation of drought in winter wheat.
