Biocontrol bacterial strain CH01 for efficiently preventing and treating citrus canker and application of biocontrol bacterial strain CH01

The invention discloses a biocontrol bacterial strain CH01 for efficiently preventing and treating citrus canker and an application of the biocontrol bacterial strain CH01. The biocontrol bacterial strain CH01 is bacillus cereus, and is assigned with the preservation number CGMCC NO.11677. It is shown from a flat inhibition test result the bacillus cereus CH01 can obviously inhibit growth of xanthomonas axonopodis pv. citri, and has an obvious inhibition effect on multiple pathogenic fungi. Further, the bacillus cereus CH01 shows great hydrolase activity in vitro. It is shown from a greenhousetest result that the bacillus cereus CH01 can effectively prevent development of citrus canker, and it is shown from a field trial result that the bacillus cereus CH01 has 65.46% of prevention effecton citrus canker. Therefore, the biocontrol bacterial strain CH01 can be used as a biocontrol preparation and efficiently prevent citrus canker. 本发明公开了种高效防治柑橘溃疡病的生防菌株CH01及其应用。生防菌株CH01为蜡状芽孢杆菌(Bacillus cereus)，其菌株保藏号为CGMCC NO.1
