采用二元二次饱和D—最优设计,研究分析了种植密度、复合肥施用量对马铃薯产量及其效益的影响,建立种植密度(x_1)、复合肥施用量(x_2)与产量、纯收益、产投比间的关系数学模型,模拟分析提出了马铃薯在间套作条件和单作条件下实现高产高效的栽培技术模式。可提供生产实际应用。
The effects of planting density and compound fertilizer application on potato yield and its benefits were studied and analyzed by using binary quadratic saturation D-optimal design. The effects of planting density (x_1), compound fertilizer application (x_2) and yield, net income , Production-to-investment relationship between the mathematical model, the simulation proposed that the potato in the intercropping conditions and single-cropping conditions to achieve high yield and efficient cultivation techniques. Can provide practical production.
