Abstract：The sun -cured tobacco was selected to study the effects of foliar spraying molybdenum fertil-izer with different times on yield and main chemical compositions,neutral aromatic substances and sensory quality through a field experiment.The results showed that foliar spraying molybdenum fertilizer could signifi-cantly improve the output value,yield and proportion of 1 ~3 -level leaves.It could improve the contents of total sugar,reducing sugar,potassium and molybdenum,and reduce the contents of nicotine,total nitrogen and chlorine in tobacco leaves.The change trend was more evident with the foliar spraying molybdenum fertil-izer for twice.It also could improve the total content of neutral aromatic substances and sensory quality.And foliar spraying molybdenum fertilizer for one time was better to the upper leaves and that for twice was better to the middle leaves.Thus,foliar spraying molybdenum fertilizer could obviously improve the yield and quality of sun -cured tobacco.
