R3, and the preservation number of the herbapiril R3 is CCTCC (China Center For Type Culture Collection) NO: M 20231757; the rice seed endophytic bacterium stenotrophomonas R5 is Shenotrophomonas sp. R5, and the preservation number of the rice seed endophytic bacterium stenotrophomonas R5 is CCTCC (China Center for Type Culture Collection) NO: M 20231758. The compound microbial suspension is used as a seed coating agent to coat tobacco seeds, and growth of tobacco root systems can be remarkably promoted.

Herbaspirillum bacterial strains are engineered to express or overexpress one or more proteins and / or attenuate expression of or delete one or more genes involved in nitrogen fixation and its regulation. This enables the diazotrophic bacteria to secrete more ammonia. The engineered bacteria arc introduced to agricultural plants, or seeds for growing such, forming a symbiotic relationship that results in increased nitrogen availability to the plant and improved plant agronomic traits.

This invention relates to the field of microbial technology, and provides a composite microbial suspension comprising a *Streptococcus pyogenes* R3 suspension and a *Cyclocarya pallida* N4 suspension in a volume ratio of 1-2:1-2; the *Streptococcus pyogenes* R3 classification name is... Herbaspirillum sp. R3 was deposited on September 20, 2023, at the China Center for Type Culture Collection (CCTCC), Wuhan University, Wuhan, China, with accession number CCTCC NO: M 20231757; the taxonomic name of Chlorella N4 is... Chryseobacterium endophyticum N4 was deposited on March 31, 2025, at the China Center for Type Culture Collection (CCTCC), Wuhan University, Wuhan, China, with accession number CCTCC NO: M 2025633. The aforementioned composite microbial suspension promotes nitrogen fixation and nitrogen conversion.

The present application relates to the field of agricultural microorganism technology, and particularly discloses a microbial inoculum for promoting growth in the prevention and treatment of rice smut, and a preparation method and application thereof. The present application provides an application of the grass Helicobacter R3 in the preparation of a microbial inoculum for promoting growth in the prevention and treatment of rice smut, and the classification name of the grass Helicobacter R3 is Herbaspirillum sp. R3, which was preserved in the China Center for Type Culture Collection on September 20, 2023, at an address of Wuhan University, China, Wuhan, with a preservation number of CCTCC NO: M 20231757. The microbial inoculum prepared from the grass Helicobacter R3 bacterial suspension, xanthan gum and ascorbic acid in a specific ratio, in combination with a disinfectant, can be applied to the prevention and treatment of seed diseases of rice, can significantly reduce the bacterial carrying rate of the rice smut pathogen of rice seeds, and can also alleviate the oxidative damage caused by seed disinfection and improve the seed germination rate.
