The invention discloses a microbial agent capable of chelating residual nutrients in soil and reutilizing the residual nutrients, and belongs to the technical field of microbial agents. The microbial agent is prepared from the following raw materials: 30-50 parts of rhodosporidium toruloides, 10-20 parts of bacillus subtilis, 10-16 parts of bacillus licheniformis, 15-25 parts of bacillus amyloliquefaciens, 10-15 parts of humic acid, 3-5 parts of chelating agent, 1-3 parts of dispersing agent and 1-3 parts of auxiliary agent. The four-in-one microbial inoculum composition and the addition of the chelating agent humic acid have multiple effects of adjusting soil environment, fully utilizing soil nutrition, improving crop yield, improving crop disease resistance, reducing fertilizer use and the like, increase value and improve efficiency, and have wide economic value and social value. |
