Three kinds of commercial microbial inoculants including enzyme bacteria (J), organic fermenting bacteria (Y), gymboree (B) were employed to ferment fine-grained (diameter <1 mm, T) and coarse-grained (diameter 1-3 mm, C) Acacia mangium bark to prepare substrates, and the physicochemical properties and the influence on the growth of white radish ‘Yangzhouyuan’ were investigated, in order to provide a scientific basis for utilization of the bark of A. mangium . The results showed that the bark supplemented with the bacterial agent could promote the growth of radish. The content of available phosphorus and available potassium in the substrate was the highest, which was 57.60 and 775.50 mg/kg, respectively, and significantly higher than that of other treatments. Whole plant fresh and dry weight of white radish ‘Yangzhouyuan’ grown on the substrate treated with enzyme bacteria was the highest, followed by gymboree and organic fermenting bacteria. The content of total phosphorus and potassium in the white radish ‘Yangzhouyuan’ was the highest, which was 3.95 and 45.20 g/kg correspondingly. The results suggest that the bark of A. mangium treated with enzyme bacteria had the best effect, and was suitable to be used as a substrate.

Key words: bark of Acacia mangium, decomposition, radish, bacterial agent, nutrient content
