| 摘 要： | 采用四因素五水平二次回归正交设计方案,在盆栽控制条件下,对大豆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,两因素间交互耦合效应。结果表明,各因素对大豆产量均有影响,其作用大小顺序是:水分>钾肥>氮肥>磷肥,且钾肥是负效应。

| Abstract: | A two return interactive design of four factors and five levels was carried out under tub experiments to study the interaction of water and fertiliz er coupling. On the basis of water and fertilizer coupling model put forward, th e effect involved in main and single factors, interaction coupling were analyzed and studied respectively. The results showed that all factors were influent to soybean yield, while the influencing sequence from large to small is : soil mois ture > K fertilizer > N fertilizer> P fertilizer, and K fertilizer is inverse ef fect. |
