纤用亚麻高产高效栽培技术方案的优化决策分析

Optimum Decision-Making Analysis of Cultivated Technique Scheme for the High Yield and High Benefit of Fibrous Flax

采用回归正支旋转设计的方法.研究了纤用亚麻籽粒产量、原茎产量和毛收益与主要栽培因子播种期、播种量、施氮量、施磷量之间的关系。并通过对所建模型的解析和优化模拟以及对所选方案的多目标决策分析,提出了获得纤用亚麻高产高效单一目标及综合目标栽培的优化方案,可供生产中选用。

The design method of quadratic orthogonal ratation regression had been applied in the present experiment to study the relationship between fibrous flax grain yield, stem yield , gross income and the primary factors of fibrous flax cultivation: seeding time, seed rate, amount of nitrogen applied, amount of phosphorus applied, through the optimum analysis and simulation of the yield and economic profit models, the appropriate cultivated technique schemes for obtaining single and synthetical aims of high-yield and high-benefit of fibrous flax were proposed in this paper, which can readily be selected for practice.
