Abstract：The L9 (34 )orthogonal experiment was conducted to study the effects of different proportions of nitrogen,phosphorus and potassium on neutral aroma component and quality of Long’an flue -cured tobac-co.The results showed that tobacco agronomic traits of N2P2K3 and N2P3K1 treatments were better,followed by N3P2K1,N2P1K2 and N2P3K2.Tobacco economic traits of N2P2K3 treatment were better,followed by N3P3K2 and N2P3K1.Tobacco chemical components of N2P1K2,N2P2K3 and N2P3K1 treatments were bet-ter.Neutral aroma components and sensory quality of N2P2K3 treatment were better.In general,N2P2K3 treatment (applying pure nitrogen of 6 kg,pure phosphorus of 11 kg and pure potassium of 24 kg per 666.7m2 )was the optimal fertilization mode.It could promote tobacco growth and development,improve aro-ma and quality,and increase production.
