Abstract: In order to select a suitable photosynthetic bacteria inoculants concentration to improve the tomato growth with pot experiment, we studied the effects of three concentrations of high efficient photosynthetic bacteria inoculants on soil microbial properties. The experimental results showed that, significant increases was observed in the population of soil bacteria and soil Actinomycetes with photosynthetic bacteria inoculants, and prominent decrease in that of soil fungi. Soil urease, acid phosphatase and catalase activities were all improved by the application of photosynthetic bacterial inoculants. The photosynthetic bacterial inoculants diluted 100 times plus chemical treatment was the most remarkable in the experiment, which was more conducive to the soil microbes and environment.  

Key words: photosynthetic bacteria, soil microorganism, soil enzymes
