摘要
对喷灌条件下冬小麦水肥耦合效应进行了研究，探讨了不同灌水施肥处理对冬小麦产量、耗水规律以及对土壤中全氮、硝态氮含量等的影响，建立反映冬小麦产量与施肥量、灌水量关系的数学模型，提出喷灌条件下冬小麦适宜的灌水定额。
This paper analyzes in detail the effects of different water and fertilizer application treatments on yield, water consumption and total nitrogen and nitrate content in winter wheat. Based experimental data, a mathematical model that shows the relationship between yield and water and fertilizer application is developed. The optimal water and fertilizer application determined with the model is also presented.
