Experiment study on the crop’s water-nitrogen production function

  • Crop water-nitrogen production functions were presented based on the crop's water production function theories and field water nitrogen interaction experiments.A final crop yield model and a dynamic crop yield model were studied in detail Parameters of the dynamic crop yield model were estimated from experimental data provided by J.J.Groot,the model was tested in Yongledian Beijing,and the good results were obtained.
