Abstract

The invention relates to the application of nano-titanium dioxide in promoting spore production of plant anthracnose bacteria. The invention also relates to a method for promoting spore production of the plant anthracnose fungus. The nano-titanium dioxide of the present invention has the effect of greatly promoting the spore production of plant anthracnose bacteria. Because the plant anthracnose bacteria are not easy to produce spores, it greatly affects the progress of scientific research projects. The present invention is helpful to promote some projects or research, and has great theoretical research and application value.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a new application of nano titanium dioxide. Background technique [0002] Nano-titanium dioxide (TiO2) is a crystal with a diameter of less than 100 nanometers. It is a white loose powder titanium dioxide and is generally used as an industrial material. Its functions mainly include several aspects. First, it has a bactericidal function. It can be used to treat tap water with TiO2 photocatalytic oxidation, which can greatly reduce the number of bacteria in the water. It has no mutagenic effect after drinking and meets the standard of safe drinking water. Function, nano TiO2 can not only absorb ultraviolet rays, but also reflect and scatter ultraviolet rays, and can also pass through visible light. It is a physical shielding ultraviolet protective agent with superior performance and great development prospects. and plastic fillers; the third has photocatalytic function, activating Ti...
