Abstract: A field trial was carried out to explore the effects of application of high-carbon base fertilizer with nitrogen on growth, yield and quality of flue-cured tobacco in Mudanjiang City, Heilongjiang Province. Four treatments were set up as follows: CK（conventional nitrogen application rate, no high-carbon base fertilizer）; T1(conventional nitrogen application rate, supplemented with 900 kg·hm-2 of high-carbon base fertilizer); T2(85%conventional nitrogen application rate, supplemented with 900 kg·hm-2 of high-carbon base fertilizer); T3(70%conventional nitrogen application rate, supplemented with 900 kg·hm-2 of high-carbon base fertilizer). The results showed that the agronomic traits of the test tobacco at all growth stages were improved under T1 treatment, while they were decreased under T3 treatment. The total nitrogen（1.59%, 1.65%） and nicotine contents（1.71%, 1.99%） of flue-cured tobacco in C2 L and B2 F were increased under T1 treatment. The potassium contents of middle leaves were respectively increased by 1.68% and 1.69% under T1 and T2 treatments respectively. Compared with CK, the total sensory score of middle and upper tobacco leaves under T1 treatment was increased by 4.06% and 5.92% respectively. Meanwhile, T1 treatment could also improve the tobacco yield output value and the proportion of mid-high grade tobacco leaves. In conclusion, the combined application of 45 kg·hm-2 of nitrogen and 900 kg·hm-2 of high-carbon base fertilizer could improve growth, economic characteristics and quality of flued-cured tobacco cultivated on albic soils in Mudanjiang.
