Effects of profitable soil microorganism propagation agent on the growth yield and quality of tobacco

To research effect of profitable soil microorganism on the growth of tobacco，different fertilizer amount mixed with profitable soil microorganism propagation agent was applied in the production of tobacco. The results showed that 70% amounts of normal fertilizer mixed with profitable soil microorganism propagation agent can promote the growth of tobacco distinctly compared with control group. Compared with CK，the stem height was increased respectively by 21.5%，11.7%，7.4%，and the middle leaf area was increased respectively by 20.7%，1.3%，6.5% in rosette stage，bud stage and topping stage. T3 can improved the quality and potassium content of tobacco leaves，and the market value was improved by 14.6% compared with CK.
