Abstract

The application discloses a bacillus velezensis strain and application thereof in disease prevention and growth promotion, the strain is preserved in the China General Microbiological Culture Collection Center on May 14, 2024, the preservation number is CGMCC No.30619, and the strain is named bacillus velezensis Bacillus velezensis. When the strain is applied to the field of agricultural biological control, a biological membrane can be formed to stably colonize in the rhizosphere of plants, a variety of plant pathogenic fungi can be strongly and broadly inhibited, and substances such as IAA and iron carrier can be produced to promote plant growth. The cucumber wilt potting prevention effect of the bacillus velezensis bacterial suspension can reach 56.36%, and the bacillus velezensis bacterial suspension has a certain growth promoting effect on cucumbers, is a biocontrol strain with excellent performance, and has a good development and application prospect.
