摘要
试验旨在探究主客观赋权的4种评价方法在广西青贮类玉米综合评价中的作用.试验基于熵权及人工赋权的逼近理想解排序法(TOPSIS)、多准则妥协解排序法(VIKOR)、秩和比综合评价法(RSR)及耦合协调度法对广西柳州、玉林、百色、南宁、宜州5个区域的12个青贮类玉米品种的产量、品质、抗病性等18个农艺性状进行分析.结果显示:桂单242、桂单673、兆玉215在这5个区域中综合表现较好,具有高产、优质、适应性强等特点,适合大面积推广种植.研究表明,VIKOR法在多指标下表现更加贴近产量排序,TOPSIS和RSR法的评价结果非常接近,RSR法的分档等级能够更加具体区分排序的效果.耦合协调度法能够表现各指标之间的协调程度,能够评价一个品种在当地的整体适应性水平.
Abstract
This experiment aimed to explore the role of four evaluation methods with subjective and objective weighting in the comprehensive evaluation of silage corn in Guangxi.The trial evaluated 12 silage corn varieties from five regions of Liuzhou,Yulin,Baise,Nanning,and Yizhou in Guangxi,across 18 agronomic traits such as yield,quality,and disease resistance,using the TOPSIS,VIKOR,RSR,and coupling coordination degree methods based on entropy weight and artificial weighting.The results showed that Guidan 242,Guidan 673,and Zhaoyu 215 had the best comprehensive performance in these five regions,characterized by high yield,excellent quality,and strong adaptability,making them suitable for large-scale promotion and planting.The results indicate that the VIKOR method performed more closely to the yield ranking under multi-indicators,the evaluation results of the TOPSIS and RSR methods were very similar,and the grading level of the RSR method could more specifically distinguish the sorting effect.The coupling coordination degree method could reflect the coordination among various indicators,capable of evaluating the overall adaptability level of a variety in the local area.
