作物水分与氮素生产函数的实验研究

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

  • 摘要: 在田间水肥耦合试验的基础上,对水分生产函数的概念加以拓宽,提出了水分、氮素生产函数的概念,并建立了最终产量模型和动态产量模型,进行了参数求解,模型模拟结果和田间试验结果符合较好.

     

    Abstract: 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.
