Abstract

The antagonistic bacteria provided by the present invention is isolated from the potato rhizosphere soil of the disease and obtains a strain of Bacillus mohaiwei CJX-61, and the Bacillus mohaiwei CJX-61 is named as Bacillus mojavensis . It is preserved in the General Microorganism Center of China Microbiological Culture Collection Management Committee, and the preservation number is CGMCC NO.17660. Bacillus mohewei CJX‑61 has the ability to produce chitinase, cellulase, β‑1,3‑glucanase, protease, siderophile, and HCN. CJX‑61 is effective against Fusarium oxysporum, Pyrium oryzae, Sclerotinia sclerotiorum, Fusarium moniliforme, Sclerotinia sclerotiorum, Botrytis cinerea, Fusarium graminearum, Alternaria solani, Fusarium elderberry, etc. All plant pathogenic fungi have a good inhibitory effect. Bacillus mohewei CJX‑61 confers strong defense against potato black mole and increases potato yield under field conditions.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a strain of Bacillus mohaiwei CJX-61 and its application. Background technique [0002] potato( Solanum tuberosum L.) is the fourth most important food crop in the world after corn, rice and wheat. It is rich in nutritional value and contains 8 essential amino acids and multivitamins needed by the human body. As people pay more attention to the potato-related planting industry, the potato planting area is expanding year by year. At the same time, the pathogenic microorganisms in the soil are increasing, which affects the normal growth of potatoes. Among them, potato black mole disease caused by Rhizoctonia solani is a soil-borne disease that is destructive to potatoes and seriously damages the yield and quality of potatoes. At present, chemical methods such as chemical reagents and pesticides are mainly used to solve this problem, but the use of chemical pesticides wil...
