| Abstract: | Through the enrichment of samples, the selective culture was used to isolate the chemoautotrophic sulfide bacteria; the alkaline soil in Daqing was used as the experimental material, and the pH value of alkaline soil was determined by pH meter through the addition of sulfide bacteria and auxiliary materials. Sulfurizing bacteria LH-1 was isolated and used to improve alkaline soil. Adding 0.27% sulfur powder mixed with sulfurizing bacteria had the most obvious effect. After two and a half months of improvement, pH could be reduced from 10.53 to 8.23. |
