- Abstract
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 differences 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.
