To investigate the improvement effect of bio-organic fertilizer on the growth of Eucalyptus and soil properties, using Dongmen No.29 as the material, a two-year field experiment with different proportions of organic fertilizer replacing chemical fertilizer was conducted. The results showed that the 75% substitution treatment had the best promoting growth and soil improvement effects. The growth indicators of Eucalyptus and soil nutrients, pH value, and density were all significantly improved. It was recommended that the local Eucalyptus artificial forests adopt the fertilization mode of 75% bio-organic fertilizer replacing chemical fertilizer.
