Effects of Rapeseed-cake Fertilizer on Chemical Components and Sensory Quality of Tobacco in Luohe

In order to study the effects of rapeseed- cake fertilizer on the chemical components and sensory quality of tobacco in Luohe,we tested and analyzed the chemical components of C3F- class and B2F- class tobacco leaves treated with different rates of rapeseed- cake fertilizer,and evaluated the sensory smoking quality of single- material cigarette made of the above leaves. The results showed that the application of rapeseed- cake fertilizer could reduce the chlorine content in tobacco leaf,increase its potassium content,and coordinate its chemical components; the treatment with 80% rapeseed- cake fertilizer was the best. Applying rapeseed- cake fertilizer could improve the sensory smoking quality of tobacco leaf,and the treatment with 80% rapeseed- cake fertilizer obtained the best effect.
