Abstract：In order to alleviate soil acidification, decrease tobacco morbidity and improve tobacco leaf quality and yield in Chongqing tobacco planting area,the effects of biochar,soil conditioner and their ap-plication combined with Heijingkang,Qingkuxiao on flue-cured tobacco were studied. The results showed that biochar applied alone could decrease total morbidity,improve the chemical component coordination of flue-cured tobacco leaves,decrease the yield,production value and sensory quality. Heijingkang,Qingku-xiao applied with biochar could increase the yield and production value of flue-cured tobacco leaves,and decrease tobacco morbidity, improve the chemical component coordination and sensory quality of flue-cured tobacco leaves. Soil conditioner applied alone had no significant effect on economic character of flue-cured tobacco,could decrease sensory quality of flue-cured tobacco leaves,tobacco morbidity,and im-prove the chemical component coordination of flue-cured tobacco leaves. The effect of soil conditioner ap-plied with Heijingkang and Qingkuxiao on economic character,tobacco morbidity and chemical component coordination of flue-cured tobacco leaves was poorer than soil conditioner applied alone,but which could improve the sensory quality of flue-cured tobacco leaves. Overall, biochar applied with Heijingkang and Qingkuxiao could increase the yield and quality of flue-cured tobacco.
