冬小麦水肥增产耦合效应模型研究

On the model of water-fertilizer interaction for increasing the yield of winter wheat

本文以田间试验为基础，采用二次通用旋转设计，选择影响小麦产量与构成产量的主要因子──水肥方案，建立了产量和构成因素的数学模型，并应用计算机技术将模型图形化．通过对模型的分析，探讨了水肥增产耦合效应的一些特点和规律，并提出了实现一定产量目标的最佳水肥投入指标，可作为指导中低产麦田生产的参考．

Based on the field test, by using the quadratic general spinning design, a mathematical model for wheat yield and its constitutive factors is established. Water and fertilizer are considered as the main factors affecting the yied. The characterictics and laws of water- fertilizer interaction for increasing the yield are discussed and the suitable amount of water and fertilizer for a certain yield can be calculated.
