Column and pot culture experiments were carried out to study the effects of saline-alkali-tolerant bacteria screened from coastal saline-alkali soil combined with organic matter on the formation of saline-alkali soil aggregates and the growth of corn. Results showed that, the inoculation with bacterial strain M6 that can decompose straw and secrete extracellular polymer substances combined with straws that decompose directly in soil has the best effect on the formation of saline-alkali soil aggregates. The percent of large macroaggregates increased to more than 60%. Compared with the decomposed manure the undecomposed straws has a better effect on the formation of saline-alkali soil aggregates. Saline-alkali soil inoculated with bacterial strain M6 has a better effect on the formation of soil aggregates compared with inoculation with bacteria of single function that can decompose straw or secrete extracellular polymer substances. Seed germination, livability and dry weight of maize were all promoted under the inoculation with bacterial strain M6.
