Effects of Different Types of Tobacco Cultivated Soil on Tobacco Quality in Zunyi

[Objective] The relationship between tobacco quality and types of tobacco cultivated soil in Zunyi was studied to discuss the suitability between agrotype and planting of tobacco,and then provide the relative information for the reasonable design of tobacco-growing region in Zunyi.[Method] This study analyzed the physical appearance,chemical composition,and the sensory quality of tobacco of four tobacco cultivated soils in Zunyi.[Result] The results showed that four soils appeared significant differences from the comprehensive analysis of physical apearance of tobacco(P0.05),the yield level of per unit area of paddy soil was the highest in four soils.Four soils did not appear significant differences from the analysis of chemical composition of tobacco(P0.05),but the compatibility of yellow soil was the best in four soils by analysis of chemical composition in different soils(P0.05).However,the quality of tobacco three upland soil(yellow soil,rendzina soil,and purple soil) was better than paddy soil from the analysis of the sensory quality of tobacco(P0.05).[Conclusion] The optimum tobacco cultivated soil is yellow soil and rendzina soil,which indicated that the two soils were applied to plant the tobacco in programming.
