Streptomyces lincolnensis capable of preventing and treating peach brown rot and application of streptomyces lincolnensis

Abstract

The invention relates to streptomyces lincolnensis capable of preventing and treating peach brown rot. The streptomyces lincolnensis is preserved in China General Microbiological Culture Collection Center (CGMCC) on December 17, 2020, and has a preservation number of CGMCC No.21377. The invention also relates to application of the streptomyces lincolnensis in preventing and treating the peach brown rot. The streptomyces lincolnensis disclosed by the invention has a very strong inhibition effect on various plant pathogenic bacteria of the peach brown rot and the like on a flat plate, and volatile metabolites of the streptomyces lincolnensis have a very good prevention and control effect on the growth of the pathogenic bacteria of the peach brown rot. The strain has potential commercial development and application values in biological control practice of diseases. The strain also has broad-spectrum antagonistic activity, shows a relatively strong bacteriostatic effect on pathogenic bacteria such as xanthomonas citri, pseudomonas angulate holland and the like, and also has a very good bacteriostatic effect on pathogenic fungi such as tobacco botrytis cinerea, valsa mali, thielaviopsis basicola and the like.

Description

Technical field[0001]The present invention relates to the field of prevention and treatment of fruit trees, and more particularly to the formation of Lincoln austerius and its use of peer brown rot.Background technique[0002]my country's peach cultivation area and the first world of peach production are important in the country. Peach is one of my country's main fruit resources. It has planted nationwide. It is mainly distributed in East China and North China. It is not only nutritious, sweet and sweet, and can processed into a juice, canned, etc., which is deeply loved, while It also has a huge economic interest. According to statistics, in 2015, my country's peaches, total consumption is 13.11 million T, 1.32 million T, total amount accounts for 66% of the total total peach in the world. However, the high results of peaches in my country are relatively low. The main reason is due to pathogenic microorganisms infected, resulting in rotorious fruits, seriously affecting the quality o...

Problems solved by technology

Not only that, the damage caused by the brown rot fungus of peaches is even more serious in the process of storage, transportation and consumption after harvest, and it has brought huge losses to the edible value of fruits and the economic income of fruit farmers.

[0004] At present, the control of peach brown rot is mainly based on chemical agents, which have the advantages of simple operation and low cost, but the use of chemical fungicides is likely to lead to enhanced drug resistance of pathogenic bacteria and environmental pollution, and may endanger ecological security and environmental protection. human health
