Abstract

A strain of streptomyces producing chitinase and its application, the invention relates to a strain of streptomyces producing chitinase and its application. The purpose of the present invention is to solve the problem that existing methods for controlling soybean gray mold and black spot have hidden dangers of pesticide residues. A strain of chitinase-producing Streptomyces of the present invention is Streptomyces (Streptomyces sp.) G6 , preserved in the General Microorganism Center of China Microbiological Culture Collection Management Committee, the preservation address is No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing, the preservation date is February 2, 2018, and the preservation number is CGMCC No.15334. The application of the chitinase-producing streptomyces of the present invention refers to the application in the prevention and control of soybean diseases. Strain G6 not only has chitinase activity, but also has good antagonistic effect on soybean gray mold and black spot, has no pesticide residue, and does not produce drug resistance. The invention is applied to the technical field of environmental microorganisms.

Description

technical field

[0001] The invention relates to a strain of streptomyces producing chitinase and its application. Background technique

[0002] Soybean is the main food crop in my country, and it is also the main economic crop and feed crop. With the continuous growth of the population and the improvement and improvement of living standards, the yield and quality of soybeans are the focus of attention. Botrytis cinerea and black spot of soybeans can infect soybeans throughout the growth period, causing soybean diseases, and are distributed in Jilin, Liaoning, Heilongjiang, Jiangsu, Sichuan and other provinces. According to existing reports, soybean gray mold and black spot not only infect soybeans, but also have pathogenicity on plants such as ginseng, citrus, sweet potato, cabbage, jujube fruit, and rose.

[0003] At present, the main method of controlling soybean gray mold and black spot is still based on chemical pesticides, but in view of the hidden dangers of pesticid...
