Embodiment

[0023] The bacterial strain SB177 of the prevention and treatment of strawberry replanting disease of the present embodiment can be extracted on March 19, 2009 and preserved in the China Type Culture Collection Center, the preservation number is: CCTCC NO: M209037, and the Latin formal name used at school is Bacillus amyloliquefaciens bacterial classification. The species has the following characteristics: the colony is white to milky white opaque, the surface is rough, and the edge of the colony is irregular. The cells are short rod-shaped, with endophytic spores, and the cysts are enlarged and oval, G+. Can produce amylase, lipase, protease, peptidase, sucrase. It has a strong antagonistic effect on plant pathogens Verticillium, Fusarium, Rhizoctonia, Aspergillus and Phytophera.

[0024] The biocontrol agent prepared by the bacterial strain SB177 of the control strawberry replanting disease of the present embodiment, its preparation method may further comprise the steps:

Abstract

The invention discloses a strain SB177 for controlling strawberry replant diseases and a preparation thereof, belonging to the technical field of preventing and curing diseases of fruit trees. The strain SB177 and the preparation thereof are specially used for biological control of the fruit trees. The microbial inoculum also can be used for controlling strawberry overground part diseases such as powdery mildew of strawberry, gray mold, etc. The preparation prepared from the strain has the performances of long shelf life, high control effect, wide control spectrum as well as promoting and increasing production. The invention is realized by the following technical proposal: the strain SB177 for controlling strawberry replant disease is bacillus amyloliquefaciens which is the Latin literature name and is preserved in China Center for Type Culture Collection (CCTCC) in March 19th, 2009 with the preservation number of CCTCC NO: M209037.

Description

technical field [0001] The invention relates to a bacterial strain and its preparation, more specifically to a bacterial strain SB177 for preventing and treating strawberry replanting disease and its preparation, which belongs to the technical field of fruit tree disease prevention and treatment, and is specially used for biological control of fruit trees. Background technique [0002] Replanting disease refers to the phenomenon that the same crop is continuously planted in the same field, resulting in poor growth and development of the crop, aggravation of the disease, and a serious decline in crop yield and quality. In Japan, this kind of problem is called the phenomenon of forbidden land, continuous cropping obstacle or continuous cropping obstacle, and in European and American countries it is called replant disease (Replant disease) or replant problem (Replant problem). [0003] Over the years, the introduction, breeding and protected cultivation technology of new strawb...
