Abstract

The invention belongs to the technical field of microorganisms. The invention discloses a walnut leaf endophytic biocontrol bacterium, which belongs to bacillus, the preservation number of the walnut leaf endophytic biocontrol bacterium is CGNCC No: 22705, and the 16S rDNA nucleotide sequence of the walnut leaf endophytic biocontrol bacterium is shown as SEQ ID NO.1. The walnut leaf endophytic biocontrol bacterium is high in safety, capable of effectively preventing and treating walnut leaf blight caused by walnut anthracnose or fusarium laminar, the walnut leaf endophytic biocontrol bacterium has low production and use cost, is free of residues, is high in safety, is environmentally friendly and is good in prevention and treatment effect.

Description

technical field [0001] The invention belongs to the technical field of microbes, and in particular relates to an endogenous biocontrol bacterium in walnut leaves and a preparation method and application thereof. Background technique [0002] Walnut (Juglans regia) is an important woody oil crop in my country. Anthracnose caused by glenospora anthracnose and leaf blight caused by fusarium laminarum will cause a large area of ​​leaf death, seriously affecting the photosynthesis of the tree and the accumulation of nutrients in the tree. At present, the control of these two diseases mostly focuses on chemical control. The inventors found that Bacillus subtilis Bacillus subtilis It has a significant inhibitory effect on the spore germination and hyphal growth of Fusarium laminarum and G. anthracnose, but the antifungal activity of this fungus has not been reported in walnut leaf diseases. Contents of the invention [0003] The technical problem to be solved by the present inv...
