针对烤烟品种综合评价传统分析方法仅从一个性状进行分析,对其他性状仅做定性描述导致评价结果不够准确的问题,运用灰色系统理论中的灰色局势决策原理,对河南省南阳地区的烤烟品种进行综合评价。结果表明:在注重性状权重的情况下,烤烟品种综合性状的优劣次序依次为云烟87、云烟85、中烟100、中烟98、K326、9717、8541、39511和中烟101;这与生产上南阳地区烤烟主栽品种为云烟87和云烟85,搭配品种为中烟100和K326的实际情况基本一致。灰色局势决策法为烤烟新品种的综合评价提供了一种较为全面的量化分析方法,解决了多目标间的不可公度性和目标间的矛盾性,弥补了传统分析方法仅从产量单一性状指标入手导致偏颇的不足。
According to the traditional analysis method of comprehensive evaluation of flue-cured tobacco varieties, only one trait was analyzed and only the qualitative description of other traits resulted in the inaccurate evaluation results. By using the gray situation decision-making principle in gray system theory, the flue-cured tobacco varieties in Nanyang area of Henan Province Overview. The results showed that the order of the comprehensive traits of flue-cured tobacco varieties was Yunyan 87, Yunyan 85, Zhongyan 100, Zhongyan 98, K326, 9717, 8541, 39511 and Zhongyan 101 under the condition of focusing on trait weight. The main cultivars of flue-cured tobacco in the upper Nanyang area were Yunyan 87 and Yunyan 85, with the actual conditions of matching varieties of tobacco 100 and K326 being basically the same. The gray situation decision-making method provides a more comprehensive quantitative analysis method for the comprehensive evaluation of the new tobacco varieties, solves the incommensurability between objectives and the contradiction between the goals, and makes up for the traditional analysis methods only from single output traits indicators To start biased enough.
