Abstract: In order to explore the suitable row-spacing of ‘Yunyan 97’ in Wuling tobacco-growing region, field experiment was conducted in Water village ,Wulong County, Chongqing City from April to December in 2012 and effects of row-spacing on agronomic characters, chemical composition and economic characters of Yunyan 97 were studied. The results showed that: Wider row-spacing could improve tobacco-growing situation at the 60th day after transplanting, that row spacing 120 cm×50 cm and 120 cm×60 cm performed better. Total sugar content and reducing sugar content of flue-cured tobacco were all higher, and row spacing 120 cm×40 cm could make a better chemical compatibility for middle leaves. Influence of spacing on yield was greater than row spacing, but influence of row spacing on output value and high grade leaf proportion was greater than the spacing, Comprehensive analysis, in Wuling tobacco-growing region, The suitable row-spacing of ‘Yunyan 97’ was row spacing 120 cm and spacing 40 cm.
