Abstract

The invention discloses a compound flora for preventing and controlling the outbreak of Fusarium spp. in maize and its application. The complex flora is composed of Acinetobacter baumannii RFAci-1, Pseudomonas stutzeri RFPse-1, Pseudomonas japonicus RFPth-1, Burkholderia cepacia RFBur-1, oligotrophic monocytotrophs maltophilia Bacillus RFSte‑1, Bacillus amyloliquefaciens RFBac‑1, Agrolysobacter RFLys‑1 and Enterobacter ludwig RFEnt‑1. The compound flora has a stable structure and has the characteristics of high-efficiency biocontrol and growth promotion. Inoculation into the soil can significantly reduce the incidence of Fusarium disease caused by Fusarium spp. in the main corn varieties in my country, and can also promote the growth of corn plants.

Description

Technical field

[0001] The present invention relates to a kind of control of maize seed habitat Fusarium caused by disease rhizosphere composite flora and its application, belongs to the field of crop soil-borne disease control technology. Background

[0002] The germ-dwelling microorganisms inside the seeds constitute a very rich microbial community, and they are not a single reciprocal symbiotic relationship with the plant, in which there are also pathogenic pathogenic microorganisms. Most seeds carry pathogenic fungi inside, and their dominant genera are Fusarium species, such as Fusarium aculis, Fusarium rotiferia, Fusarium laminate, Fusarium graminearum, etc. Fusarium fusarium is transmitted mainly through vertical transmission between plant species into the plant seed, and later becomes the source of infection in the second year, which in turn causes various plant diseases.

[0003] Species Fusarium can produce toxins such as Deoxyfus Fusarium enol (DON) and Vormatoxin (FB1...
