Abstract：In order to explore the delayed effect of mineralization of different types of organic material mineralization,the pot experiment was carried out with four treatments:(1) without organic material ap-plication(TCK);(2) add maize straw(TS);(3) add pig manure(TM);(4) add biochar(TB).All these four treatments were adjusted carbon(C) /nitrogen(N) to 25 in the first year.After mineralization for one year,the major indexes about tobacco growth and quality were measured and analyzed.The results showed that the tobacco agronomic traits were significantly improved under TS and TB treatments compared to TCK and TM treatments.The activities of nitrate reductase under TM treatment and amylase under TS treatments in tobacco leaves were significantly promoted compared to other treatment at the 45thday after transplanting.Compared to the other treatments,the total N(TN) content in tobacco leaves under TS treatment at the 45thday after transplanting and total potassium(K)(TK) content in tobacco leaves under TM treatments at the 75thday after transplanting were significantly elevated. The TK content under TS treatment was higher than that under the other treatments,which resulted in the total sugar/reduced sug-ar,sugar/nicotine and K/Cl more harmonious. The highest total amount of aroma components were 191.42 μg/g and 178.27 μg/g under TS and TB treatments.In conclusion,under the same C/N ratio,af-ter mineralization for one year,TS and TB treatments could significantly improve the agronomic trait and quality of flue-cured tobacco in the central Henan province tobacco-planting area.
