This invention discloses a compound microbial agent containing Pseudomonas and its application, belonging to the field of agricultural microbiology technology. The compound microbial agent of this invention includes a Pseudomonas synthetic flora and N-acetyl-L-tryptophan. N-acetyl-L-tryptophan can effectively inhibit the growth of pathogens and effectively improve the colonization ability of Pseudomonas in the soil. The combined use of Pseudomonas and N-acetyl-L-tryptophan can increase the relative abundance of beneficial bacteria and decrease the relative abundance of harmful bacteria in continuously cropped soils; increase the positive correlation ratio of microbial interactions in continuously cropped soils; reshape the rhizosphere microenvironment of apples; and promote the growth of apple seedlings in continuously cropped soils, thereby significantly improving the control effect on continuous cropping obstacles in apples.
