METHOD FOR CULTURING TEA INCLUDING RICH CATECHIN, HAVING GOOD COLOR WHILE MAINTAINING YIELD

Japanese Patent JP2021191307

A

To provide a method for improving quality of tea leaves and increasing a yield, since, quality of tea leaves is improved by increase of chlorophyll being a coloring matter, by coating and shading of a tea field for a constant period before plucking, therefore, a color of tea leaves becomes dark green and deliciousness is also enhanced, however, there are demerits for example, due to shading, growth of tea leaves is suppressed, and an amount of catechin being a functional component is reduced.SOLUTION: There is provided a culture method of tea leaves characterized that: light whose wavelength is controlled is applied to tea leaves, for increasing an amount of chlorophyll while maintaining a yield, and increasing an amount of functional components such as an amino acid and catechin while improving a color of tea leaves. By applying a large amount of blue light, suppression of growth of sprouts due to shading, can be suppressed, and it is possible to culture tea leaves in which the amount of chlorophyll is increased, the color is improved, and catechin and amino acid are balanced each other. By applying a large amount of red light, growth of the sprouts is improved, and it is possible to culture tea leaves having a vivid green color and being characterized in rich functionality of catechin.
