采用随机区组试验设计方法，研究了不同土壤改良措施对烤烟产质量的影响，结果表明：常规施肥情况下，每667 m2减少20％烟草专用复合肥、增加50 kg生物有机肥处理的上等烟比例和产值分别较对照提高18．18％、10．15％，每667 m2增施30 kg生物炭处理的上等烟比例和产值分别较对照提高15．57％、9．79％，烟叶化学成分含量比例协调，感官质量较好；常规施肥情况下，增加50 kg／667 m2生物有机肥的处理，由于氮素供应过多，虽然产量最高，但是产值降低；而施用微生物菌剂的处理各方面性状均较对照略差。

The random-block experimentation was designed to study the effects of different soil improvement measures on the yield and quality of flue -cured tobacco .The results showed that: under the condition of conventional fertilization , in comparison with the control , the treatment of reducing the application rate of tobacco -special compound fertilizer by 20% plus increasing the application rate of biological organic fertilizer by 50 kg/667 m2 could increase the first-class tobacco ratio and production value of flue-cured tobacco by 18.18%and 10.15%, respectively;the treatment of increasing the application rate of biological carbon by 30 kg/667 m2 could increase the first -class tobacco ratio and production value by 15.57%and 9.79%, respectively;in these two treatments, the proportion of chemical composition contents in tobacco leaves was harmonious , and the sensory quality was better . Under conventional fertilization , in the treatment of increasing the application rate of biological organic fertilizer by 50 kg/667 m2 , because of excessive nitrogen supply , although the yield of flue -cured tobacco was the highest , the production value was de-creased;all characters of flue -cured tobacco in the treatment of applying microbial agent were slightly worse than those in the con-trol.
