摘要： Liming is a common practice for improving plant growth and yield on acidic soils. However, knowledge is still limited on the effect of liming on tobacco growth and leaf quality planted on acidic soil. In this study, effects of lime (Ca(OH)(2)) (0, 0.75, 1.5 and 3 t ha(-1)) on soil nutrient status (Ca2+ and Mg2+ in particular), growth, nutrient accumulation and quality of flue-cured tobacco was investigated in an acidic soil located in Anhui province, China. The results showed that liming significantly increased soil pH both 30 days after transplanting and after the harvest of the tobacco. In comparison with CK (no lime application), liming at a rate of 1.5 t ha(-1) increased leaf number and leaf dry weight by 15% and 11%, and enhanced the appearance and smoking quality of cured leaves by 7% and 9%, respectively. Moreover, liming significantly increased calcium concentration, while decreased nitrogen and magnesium concentration in the cured leaves. The increase in cured leaf quality was attributed to the improvement of chemical composition, particularly the increase in reducing sugar content. Together, our results suggest that Ca(OH)(2) application at a rate of 1.5 t ha(-1) may alleviate soil acidification and improve yield and quality of flue-cured tobacco in Anhui province, China.
