| 摘 要： | 应用五因素二次通用回归旋转组合设计 ,结合马铃薯的生产实践 ,以对马铃薯产量形成影响较大的主要栽培措施为决策变量 ,以产量为目标函数 ,建立了马铃薯密度、施磷量、施钾量、种氮肥及追氮量与产量关系的数学模型 ,并通过模拟寻优 ,提出了马铃薯单产 30 0 0kg/6 6 7m2 以上的优化栽培措施的定量化指标。当密度较小与氮、磷、钾肥施用量较少 (X1,X2 ,X3 ,X4 ,X5≤ 0 )时 ,其交互作用为正效应 ,反之 ,则为负效应。

| Abstract: | A mathematic model to describe the relation of yield with plant density, amount of P and K fertilizers, basic N fertilizer, and top dressing N fertilizer applied was established using five factors quadratic universal rotation cross design. The index for the tuber yield more than 3000 kg/667 m 2 was obtained based on analysis of the mathematic model. When plant density and amount of N, P, and K fertilizers applied were at low level(X 1, X 2, X 3, X 4, X 5≤0), the interaction of density with amount of N, P, and K fertilizers applied was positive. Otherwise, the interaction was negative. |
