Bacillus amyloliquefaciens, inoculant and application

The invention belongs to the technical field of microbial inoculants, and discloses bacillus amyloliquefaciens, an inoculant and application. The bacillus amyloliquefaciens is deposited in the China Center for Type Culture Collection, and the deposit number is CCTCC M 2018428. The ability of corn to resist saline-alkali stress can be effectively improved, the rhizosphere pH of the corn is effectively reduced to provide a corn root system with a low pH environment lower than the environment, and when the pH is 8.5, the antioxidant content in a corn plant body is significantly higher than that of a control group after the bacillus amyloliquefaciens is added, so that the ability of the corn to cope with saline-alkali stress is improved, the growth of the corn is promoted, an isolated and screened bacillus amyloliquefaciens YM6 strain can improve the ability of the corn to cope with alkali stress, and a method capable of more economically and environment-friendly improving the ability of crops to cope with advers
