Abstract:

In order to find out the effect of soil particle size composition on the quality of flue-cured tobacco in western Henan and its internal relationship,the typical tobacco planting soil and flue-cured tobacco in western Henan were selected as the study objects. The characteristics of soil particle composition and flue-cured tobacco quality were analyzed,and the relationship between soil particle composition and flue-cured tobacco quality was studied,so as to provide the basis for the regulation of tobacco soil in western Henan. The results showed that:1)The proportion of soil particle size>0.01 mm was as high as 93.06%,and the whole soil was sticky;2)The appearance quality,conventional chemical composition,physical characteristics and sensory evaluation quality of flue-cured tobacco in western Henan were good,the average value of comprehensive availability index was 0.71,and the coefficient of variation was small;3)The composition of soil particle size had an important impact on the quality of flue-cured tobacco,the proportion of soil particle size >0.01 mm was significantly positively correlated with tobacco appearance quality index,flammability,gray and comprehensive availability index. In terms of tobacco growing area in western Henan,the proportion of soil particle size >0.01 mm can be increased through appropriate soil cultivation and improvement measures,which is beneficial to the improvement of comprehensive quality of flue-cured tobacco.

Key words: soil particle size, flue-cured tobacco, quality, comprehensive evaluation, availability index
