基于烟叶化学成分墒权多目标决策的植烟土壤综合评价

Comprehensive Evaluation of Tobacco Planting Soil Based on Multi-objective Decision-making and Tobacco Chemical Component

为了综合评价不同土壤类型和土壤质地的烤烟质量,采集了149份土壤样品(包括5种土壤类型、8种土壤质地)及对应的149份云烟85(C3F)烟叶样品,对其烟叶样品的10项化学成分指标进行了比较分析,并运用基于熵权的多目标决策方法对其烟叶样品化学成分进行了综合评价。结果表明:在10项烟叶化学成分指标中,土壤类型间有6项指标差异达到极显著水平;土壤质地间有5项指标差异达到极显著水平,1项指标差异达到显著水平;各烟叶化学成分指标在土壤类型和质地间的表现不同,综合评价结果表明5种土壤类型间的表现为:紫色土>黄壤>黄棕壤>石灰土>潮土;在8种土壤质地间的表现为:粉壤>粘壤>粘土>粉粘土>壤粘土>壤土>粉砂粘壤>砂质粘壤。

In order to comprehensively evaluate the quality of tobacco grown on different soil type and soil texture,this study collected 149 soil samples including 5 soil types and 8 kinds of soil texture and the corresponding 149 Yunyan No. 85（ C3F） tobacco leaf samples in Bijie tobacco-growing areas,and carried out comparative analysis on 10 chemical components of tobacco leaf. Then multi-objective decision-making method based on entropy weight was adopted to comprehensively evaluate these chemical components. The results showed that among 10 chemical component indicators the diferences among 6 indicators were extremely significant among soil types,5 indicators had extremely significant differences among soil textures,and one indicator was significantly different. Each chemical component indicator had different expression among soil type and doil texture. The result of comprehensive evaluation indicated that the expressions of 5 soil types were purple soil〉 yellow soil〉 yellow brown soil〉 lime soil soil〉 fluvo-aquic soil; the expression of 8 species of soil textures were powder soil 〉sticky soil〉 clay〉 silty clay〉 loam clay〉 loam 〉sticky silty loam〉 sandy clay loam.
