Abstract：The effect of different organic matters with chemical fertilizer on humus carbon in tobacco-planting soil was analyzed,so as to provide scientific theoretical basis for measuring and evaluating the effects of different organic matters on the quality and fertility of tobacco planting soil. The results showed that compared with the treatment with sole chemical fertilizer ( T1 ) ,the treatments with decomposed wheat straw and chemical fertilizer ( T2 ) ,biological carbon and chemical fertilizer ( T3 ) and rapeseed cake fer-tilizer and chemical fertilizer ( T4 ) ,cattle manure and chemical fertilizer ( T5 ) could significantly increase the contents of humus carbon,fulvic acid carbon,humin carbon by 13. 71%,9. 31%,12. 57%,28. 10%and 24. 35%,6. 30%,13. 73%,14. 80% and 10. 93%,16. 11%,3. 96%,26. 27% respectively. In ad-dition, T2 , T4 , T5 treatments could significantly increased humic acid carbon content by 10. 56%, 66. 14%,103. 93% respectively. T4,T5 treatments could significantly increased the ratio of humic acid carbon to fulvic acid carbon by 32. 20% and 63. 93%,the PQ by 22. 96% and 48. 95% respectively. In summary,organic fertilizer combined with chemical fertilizer could improve the component of soil humus carbon,especially cow dung fertilizer which had obvious effect,biological carbon was the worst.
