旱塬地膜撮种玉米高产高效栽培技术方案的优化决策分析

Optimal Decision-making Analysis of Cultivated Technique Scheme for High-yield and High benefit in the Film Mulching Tuft Planting Corn on Longdon Highland.

应用系统工程的原理和方法,通过建模模拟分析,研究确定了旱源地膜撮种玉米获得高产高效单一目标及综合目标的栽培技术方案。并根据多目标综合决策分析的方法,以玉米毛收益、籽粒产量、可信度、化肥投入量、成本为综合决策目标,优选出达到玉米籽粒高产的最佳栽培技术方案。追求高产时,应增加氮、磷化肥的投入,追求高效时,应降低氛、磷化肥的投入。

Using the principle and method of the system engineering in agriculture, the cultivated technique schemes of single and synthetical aims for high-yield and high-benefit in the film mulching tuft planting corn on Longdon highland were determined. Based on the method of the multiaim decision-making analysis and regarecl corn gross margin, grainyield, precise degree, the amount of chemical fertilizer applied, investment cost as synthetical decision-making aims, optimal cultivated technique. The amount of N-fertilizer and P-fertilizer applied should be properly incresed during pursuit high-yield alone.
