一种贝莱斯芽孢杆菌菌株及其菌剂和应用
摘要：
本发明公开了一种贝莱斯芽孢杆菌菌株及其在植物真菌病害防治中的应用。所述菌株为贝莱斯芽孢杆菌菌株Bv01，其保藏号为CGMCC No.12744。贝莱斯芽孢杆菌菌株Bv01对膝曲弯孢霉菌、终极腐霉、齐整小核菌、茄链格孢菌、禾谷镰孢菌、尖孢镰孢菌的菌丝生长具有强烈的抑制作用，菌丝生长抑制率分别为85.17 %、91.54 %、90.78%、78.14%、75.69%、86.67%；贝莱斯芽孢杆菌菌株Bv01的发酵产物对膝曲弯孢霉菌、齐整小核菌、茄链格孢菌、禾谷镰孢菌、尖孢镰孢菌的菌丝生长具有明显的抑制作用，抑制率分别为96.47%、100.00%、83.14%、77.25%、87.84%。贝莱斯芽孢杆菌菌株Bv01的发酵液能有效防治番茄猝倒病、花生白绢病、小麦赤霉病。以贝莱斯芽孢杆菌菌株Bv01的发酵液为活性成分的杀菌剂在农业生产上有良好的应用价值。
摘要（英）：

The invention discloses a bacillus velezensis strain and application thereof in prevention and control of plant fungus diseases. The strain is a bacillus velezensis strain Bv01 with the accession number of CGMCC No. 12744. The bacillus velezensis strain Bv01 has strong inhibiting effects on mycelial growth of curvularia geniculata, pythium ultimum, sclerotinia rolfsii sacc, alternaria solani, fusarium garaminearum schwabe and fusarium oxysporum, and mycelial growth inhibition ratios are separately 85.17%, 91.54%, 90.78%, 78.14%, 75.69% and 86.67%; and the fermentation product of the bacillus velezensis strain Bv01 has obvious inhibition effect on the curvularia geniculate, the sclerotinia rolfsii sacc, the alternaria solani, the fusarium garaminearum schwabe and the fusarium oxysporum, andthe inhibition rates are separately 96.47%, 100.00%, 83.14%, 77.25% and 87.84%. The fermentation liquor of the bacillus velezensis strain Bv01 can effectively prevent and treat pythium aphanidermatum, scelerotium rolfsii and wheat scab. A fungicide which takes the fermentation liquor of the bacillus velezensis strain Bv01 as an active ingredient has high application value on agricultural production.
