Abstract
To seek the optimal cultivation measures of tobacco in maize-tobacco rotation system in southern Hunan,the effect of different fertilization treatments on yield and quality of flue-cured tobacco was investigated by observation on growth vigor of tobacco seedlings under different fertilization treatments and comparative analysis on yield and output value.The results showed that the proportion of superior and medium tobacco leaves,yield and quality in treatment of adding potassium,phosphorus and zinc fertilizer was highest,and the treatment of adding potassium and phosphate fertilizer followed.Treatment of N∶ P2O5∶ K2O = 1∶ 2∶ 2 and adding zinc sulfate could improve the proportion of superior and medium tobacco leaves and gain the highest yield and output value,which was the most suitable fertilization mode for tobacco area in southern Hunan.
