The invention relates to the field of biological prevention and control of banana diseases, in particular to a banana fusarium wilt antagonistic strain, a bio-organic fertilizer, a preparation method and application thereof. The banana fusarium wilt antagonistic strain is preserved in China General Microbiological Culture Collection Center on January 9th, 2017, the preservation number is CGMCC NO.13549, and the preservation name is Bacillus velezensis H-6. According to the invention, a banana fusarium wilt pathogenic bacteria 4# physiological race is adopted as an indicating bacterium from healthy banana rhizosphere soil of an onset banana garden, flat preliminary screening and secondary screening are carried out to obtain the Bacillus velezensis H-6 with strong flat inhibition effect on banana fusarium wilt pathogenic bacteria, the Bacillus velezensis H-6 can be prepared into a bio-organic fertilizer for prevention and control of banana fusarium wilt, and further study on the strain in improving the preventi
