Abstract：This study investigated the control efficacy of bio-organic fertilizer containing Bacillus amyloliquefaciens Y14 against grape gray mold and its impact on grape quality,fruit appearance,and yield.The pot experiment showed that the grape seedlings treated with the bio-organic fertilizer containing B.amyloliquefaciens Y14 had a 45％lower incidence of disease and a 60.82％reduction in infected leaves compared to the control.Field experiments conducted from 2022 to 2024 showed that after two consecutive years of continuous application of B.amyloliquefaciens Y14 bio-organic fertilizer,compared with the control,the organic acid content decreased by 37.34％,the soluble solids content increased by 12.66％,the total soluble sugar content increased by 24.41％,the vitamin C content increased by 88.13％,the polyphenol content increased by 11.9％,the longitudinal fruit diameter increased by 6.13％,the transverse fruit diameter increased by 5.28％,the fruit firmness decreased by 4.23％,the yield increased by 12.69％,and the disease index of gray mold decreased from 4.8 to 3.0,with a control effect of 37.5％.The results demonstrated that the bio-organic fertilizer containing B.amyloliquefaciens Y14 effectively controlled the occurrence of gray mold and improved the quality and yield of grapes,establishing a theoretical basis for its application in grape production.
