Abstract:
Botrytis cinerea Pers.was used as test fungus.Plate confrontation method was carried out to obtain antagonistic bacteria against Botrytis cinerea Pers.from different soil around the plant roots.The results showed that 75 bacteria were isolated and purified from different ecological soil samples.After primary screening test of tablet confrontation method,30 bacteria which had certain function of antagonism against Botrytis cinerea were verified.Separation frequency was 40.00%.And the antagonist bacteria YM8,FQ10,FQ11 had better inhibiting effect.According to the comparison,it was found that the bacteriostatic diameters of antagonistic bacteria against Botrytis cinerea was 1.5-3.0 cm,such as YM8,FQ10,FQ11.After the morphological observation and a series of physiological and biochemistry experiments,the bacterial strain YM8 was primarily identified as Bacillus licheniformis,FQ10 belonged to Bacillus brevis,FQ11 belonged to Bacillus cereus.
