AI Technical Summary
The storage of electrolytic manganese slag occupies land resources and pollutes the environment. The cost of improving saline-alkali land is high and the effect is limited. There is currently no research on the synergistic improvement of saline-alkali land by electrolytic manganese slag and organic waste.
Microbial fertilizer is prepared by mixing electrolytic manganese slag with organic waste, fermenting it with biogas, and inoculating it with Bacillus subtilis and denitrifying monocytogenes for fermentation, which is then used to improve saline-alkali land.
This has enabled the resource utilization of electrolytic manganese slag, reduced the pH value and total salt content of saline-alkali land, increased the organic matter content of soil, significantly improved crop yield, and reduced environmental pollution.
