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 flue-cured tobacco with different soil types and soil texture, 149 soil samples (including 5 soil types and 8 soil textures) and 149 samples of C3F tobacco leaf were collected. Term chemical composition index were compared and analyzed, and the multi-objective decision-making method based on entropy weight was used to comprehensively evaluate the chemical constituents of tobacco samples. The results showed that there were 6 significant differences in the soil chemical composition among 10 soil types, 5 significant differences among soil quality, The results of the comprehensive evaluation showed that the performance of the five soil types was purple soil> yellow soil> yellow brown soil> lime soil> fluvo-aquic soil. The performance among the eight soil types was: powder Soil> Clay> Clay> Flour clay> Loam clay> Loam> Silty clay> Sandy clay.
