ABSTRACT

The application of Bacillus mucilaginosus and carriers has positive effects on tobacco growth and soil microbial activity. In this paper, we investigated the characteristics of changes in tobacco growth under Bacillus mucilaginosus and carrier dosing, as well as under the effects of different fungicide additions and different carriers. The results of the study showed that (1) The addition of carriers has a good improvement effect on indicators such as plant height, maximum leaf length, maximum leaf width, and stem thickness of field tobacco. The four indicators of the biochar group were 21.32%, 5.80%, 10.39%, and 8.07% higher than those of the control group, respectively. The four indicators of the bacterial bran group were 19.10%, 7.30%, 11.45%, and 7.96% higher than those of the control group, respectively. These two carriers have the best performance. (2) The addition of Bacillus mucilaginosus has a good promoting effect on the height, maximum leaf length, maximum leaf width, and stem thickness of tobacco plants in the field, and this promoting effect generally shows a trend of "increasing first and then decreasing" with the increase of bacterial dosage. The four indicators of the moderate addition group were 26.76%, 15.24%, 19.37%, and 18.08% higher than the control group, respectively, and were higher than those in the other groups(p<0.05). (3) Overall, S2 (biochar+100g Bacillus mucilaginosus) and J2 (mycorrhizal bran+100g Bacillus mucilaginosus) treatments have the best promoting effect on the growth of tobacco in the field stage. This study can provide theoretical basis and data support for improving the quality of roasted tobacco and the microbial activity of the red soil in the southwest tobacco area.
