Abstract: The corresponding growth-promoting ability of Bacillus velezensis strain S3-1 and Pseudomonas chlororaphis subsp. aurantiaca strain JD37 was measured and found to have good growth-promoting ability.The two strains were prepared into corresponding liquid fertilizers applied to the soil which the tomatoes were grown in.It shows that the S3-1 treatment group significantly increased the content of soluble sugar,soluble protein,titratable acid and ascorbic acid in tomato fruit.This showed that watering the biological fertilizer S3-1 could effectively improve the quality of tomato fruit.Then,we plated coating of tomato rhizosphere soil.We found that S3-1 was effective in blocking more microorganisms from entering the rhizosphere of plants,especially bacteria.What's more,the rate of change was three times higher than that of the control group.After using S3-1 biological fertilizer,the dry weight and root length of the plants didn't change significantly.The further studies had shown that S3-1 biofertilizer significantly reduces theurease activity of soil.However,it had no significant effect on thesucrase activity of soil.
