Bacillus methylotrophicus, and preparation and applications of a microbial inoculum thereof

Abstract

Bacillus methylotrophicus, and preparation and applications of a microbial inoculum thereof are disclosed and belong to the technical field of agricultural microbes. The bacillus methylotrophicus HZ-9 is deposited in the China General Microbiological Culture Collection Center on April 13, 2017, and the accession number of the strain is CGMCC No.14022. The antibacterial spectrum of the strain is wide. The strain has strong inhibiting effects on pathogenic bacteria causing anthurium andraeanum bacterial leaf spot, and other pathogenic bacteria such as colletotrichum gloeosporioides, fusarium oxysporum, poplar rot pathogenic bacteria, rhizoctonia solani and botrytis cinerea. The inhibiting effects on the pathogenic bacteria causing anthurium andraeanum bacterial leaf spot are especially significant. The bacillus methylotrophicus can stably colonize anthurium andraeanum root, blades and petiole surfaces. The microbial inoculum prepared from the strain can be applied for preventing and controlling the anthurium andraeanum bacterial leaf spot and other diseases.

Description

Preparation and Application of a Strain of Methylotrophic Bacillus and Its Bacterial Agent technical field The invention provides the preparation and application of a methylotrophic bacillus strain and bacterial agent thereof, belonging to the technical field of agricultural microorganisms. Background technique Anthurium, also known as anthurium, lucky flower, and anthurium, is a plant of the genus Anthurium in the family Araceae. Its origin is the tropical rainforest area of ​​South America, and it is now widely cultivated in Asia, Europe, Africa and other places. This crop is a perennial evergreen herbaceous flower with peculiar flower shape, bright and rich colors, and a wide range of uses. It is one of the most popular and popular precious flowers in the world. In trade, the sales volume is second only to orchids. In recent years, the bacterial diseases of Anthurium anthurium have shown an obvious growth trend in the cultivation process of Anthurium, mainly including...

Problems solved by technology

Although chemical control has many advantages such as broad antibacterial spectrum, low cost, convenient use, high efficiency and stability, etc., the extensive use of chemical fungicides brings soil and air pollution, ecological balance damage, food safety threats, and pathogenic bacteria resistance to pesticides. Problems such as plant enhancement are becoming more and more serious. Therefore, people pay more and more attention to the selection of biological control methods that are highly efficient, non-toxic, non-polluting, and not easy to produce drug resistance for the prevention and treatment of plant diseases.

However, the biological control preparations and methods for bacterial diseases of anthurium are very lacking
