| 摘 要： | 在控制灌溉条件水肥耦合试验的基础上,综合考虑不同水分和氮肥用量对水稻产量的影响,提出水稻水氮生产函数——Jensen模型和水稻水肥动态生产函数——修正Morgan模型,二者模拟效果均较好,但以Jensen模型拟合度较高.该研究可为当地科学施肥和合理灌溉提供参考.

| Abstract: | On the basis of water and fertilizer coupling test under the control irrigation condition,comprehensive considered the effect of different dosage of water and fertilizer on rice yield,and put forward the model of rice water-nitrogen production function,Jensen model,and rice water and fertilizer dynamic production function,modify Morgan model,the simulation results of them were good,but the fitting degree of Jensen model was higher.The study could provide reference for the local scientific fertilization and reasonable irrigation. |
