T2 treatment had the highest yield，with seed cottonyield of 7850.00kg/hm2 and lint cotton yield of （20 3666.17kg/hm2 ，respectively. There was no significant diference compared to T treatment，and it was significantly higher than' l3 and CK treatments （P<0.05）.T3 and CK treatment increased yields by 10.1% ， 15.2% （seed cotton），and 10.3% ， 18.7% （lint cotton），respectively.[Conclusion]Under the conditions of this experiment，spraying 16.500L/hm2 15 billion CFU/mL Bacillus subtilis fermentation broth + （204号 molasses adjuvant （ T2 treatment）is beneficial for the growth and yield improvement of cotton.
