Abstract

Abstract:

To investigate the effects of biomass ash application on the physicochemical properties of tobacco-planting soil and the yield and quality of flue-cured tobacco，a field experiment was conducted with five application levels of biomass ash：1 500（T1），3 000（T2），4 500（T3），6 000（T4），and 7 500 kg·hm^-2（T5），with no biomass ash application as the control（CK）. The study systematically analyzed the effects of biomass ash on the agronomic traits，economic traits，leaf yield and quality of flue-cured tobacco，and the physicochemical properties of planting soil. The results showed that applying biomass ash improved the agronomic traits of flue-cured tobacco at the mature stage，increased leaf width and maximum leaf area，thereby enhancing tobacco yield and output value. The application of biomass ash optimized the conventional chemical components of flue-cured tobacco. It increased the total sugar，reducing sugar，and potassium contents，as well as the potassium-to-chlorine ratio in middle leaves，while decreasing the chlorine content. Among the treatments，T3 and T4 performed the best，with reducing sugar content increased by 7.32% and 7.43%，and potassium content increased by 13.73% and 15.03%，respectively. For upper leaves，the contents of reducing sugar and potassium，along with the potassium-to-chlorine ratio，were also improved，while nicotine and nitrogen contents decreased. The sugar-to-nicotine ratio in treatments with medium to high biomass ash application rates（T2-T5）was significantly（p<0.05）increased. The quality of the tobacco-planting soil was effectively enhanced with the application of biomass ash. Based on the complete dataset，principal component analysis was used to calculate the soil quality index at the mature stage，revealing that the T3 treatment had the best improvement effect and could serve as an effective measure for soil improvement and fertility enhancement. In conclusion，during the tobacco planting process，the application of 4 500?6 000 kg·hm^-2 biomass ash can effectively increase the yield and output value of flue-cured tobacco，improve the planting soil，and play a positive role in enhancing tobacco leaf yield and quality.
