在旱棚控制条件下 ,采用 31 2 - D最优饱和设计方案 ,对辽西半干旱区春小麦田水肥耦合作用进行了初步研究。在建立了水肥耦合数学模型基础上 ,分析了各因子的主因素和单因素效应、两因素和三因素间交互耦合效应以及多因子间的耦合和限制作用类型 ,并提出了以水调肥矫正模型 ,为该区水肥耦合作用的充分发挥和互馈作用的人工调控提供了理论依据。
Under the control of upstairs canopy, the 31 2 - D optimal saturation design was used to study the coupling effect of water and fertilizer on spring wheat field in the semiarid areas of western Liaoning. Based on the establishment of the mathematical model of water and fertilizer coupling, the main and single factor effects of each factor, the interaction coupling between two factors and three factors and the types of the coupling and limiting effects between multiple factors were analyzed. Model for the region to give full play to the role of water and fertilizer interaction and the role of artificial control provides a theoretical basis.
