Hami melon（Cucumis melon L.） was treated with a combination of microbial fertilizer and amino acid water-soluble fertilizer in a fertilizer trial in Ledong, Hainan to analyze the changes of complex microbial communities structure and physicochemical properties of the soil. Soil samples at different growth stages of Hami melon were collected for analysis of soil physicochemical properties and high-throughout sequencing of soil bacterial community. Soil analysis showed that the contents of soil alkali-hydrolyzed nitrogen and available potassium were increased in the treatment groups, and that the numbers of root-knot nematodes（RN） and saprophytic nematodes（SN） were decreased. High-throughput sequencing of soil microorganisms showed that the soil bacterial flora in the treatment group were relatively stable in structure, with their relationship being far between the treatment and control groups but close between treatment groups. Compared with the control group, the treatment groups were most abundant in Proteobacteria and Acidobacteria at the phylum level, and had at the class level a lower relative abundance in Alpha-proteobacteria and Gamma-proteobacteria containing pathogenic bacteria and a higher relative abundance in Nitrosomonadales which play an important role in nitrification and Myxococcales which could produce good secondary metabolites. It was concluded that the combined application of compound microbial agent and amino acid water-soluble fertilizer significantly improved the soil physical and chemical properties and bacterial community.
