Abstract

The invention relates to a broad-spectrum disease-resistant bio-control Bacillus velei and its application. The Bacillus velezensis strain BCP6 (Bacillus velezensis) was deposited in the China General Microorganism Culture Collection and Management Center on May 15, 2019, with the preservation number CGMCC No.17805. Bacillus Bellis of the present invention has significant inhibitory effect to lettuce bacterial soft rot and sclerotinia, simultaneously to Botrytis cinerea ( Botrytis cinerea ), Fusarium solani ( Fusarium solani ), Fusarium oxysporum ( F. oxysporum ), Penicillium ( Penicillium sp.) and Rhizoctonia solani ( Rhizoctonia solani ) and other plant pathogenic fungi and watermelon acidophilus ( Acidovorax citrulli ), Pseudomonas syringae ( Pseudomonas syringae ), Xanthomonas oryzae (X anthomonas oryzae ), Ralstia solanacearum ( Ralstonia solanacearum ) and Pseudomonas marginalia ( P. marginalis ) and other plant pathogenic bacteria also exhibited broad-spectrum antibacterial activity. At the same time, the Bacillus Velez exhibits salt-alkaline tolerance and has important application prospects in biocontrol.
