Abstract
A strain separation method for preventing and controlling early bolting of Angelica sinensis, and preparation of a microbial agent and use thereof, the strain is obtained by separation, purification and cultivation from rhizosphere soil of Angelica sinensis, and is identified as Bacillus spp. by Microbial 16S rDNA sequencing; the strain was deposited at China Center for Type Culture Collection on Jun. 24, 2021 under CCTCC NO: M 2021767; tThe Bacillus velezensis XG3 strain provided by the present invention can promote the seed germination of Angelica sinensis and delay the flowering of Arabidopsis thaliana for about 2 days; according to field test verification, the microbial agent can increase the root weight, root diameter and rootlet number of Angelica sinensis, can effectively prevent and control early bolting of Angelica sinensis.
