Abstract

The invention discloses a planting method for increasing the content of epigallocatechin gallate in tea leaves. The planting method comprises the following steps that a red thin film is arranged above the canopy surface of a tea garden, and through holes are formed in the surface of the thin film; the thin film enables sunlight to form single red visible light below the thin film after penetrating through the surface of the thin film; and the through holes enable sunlight spectrums not to be changed (especially short-wave spectrums such as ultraviolet rays) to irradiate on the canopy surfaces of tea trees. The method can be used in any time period of the tea growth stage, is simple and feasible, can be used in a large-area tea garden, and is low in cost. According to the method, the red thin film is used for changing the quality of the light irradiated on the canopy surfaces of the tea trees, and then the through holes are used for providing the ultraviolet light and other short-wave trace light elements for the growth of the tea trees, so that the growth state and quality component synthesis of the tea trees can be effectively adjusted, and the EGCG content in the tea leaves is increased; and compared with hybridization cultivation in the prior art, the method is short in time consumption, simple in process and high in field operability.

Description

technical field [0001] The invention relates to the technical field of plant cultivation experiments, in particular to a planting method for increasing the content of tea epigallocatechin gallate. Background technique [0002] Epigallocatechin gallate (EGCG) is the most important quality and active ingredient in tea, which has various physiological effects such as antioxidant, anti-inflammatory, antibacterial, and antitumor. The method for increasing the EGCG content of tea leaves in the prior art is to select and breed tea tree varieties with high EGCG content through traditional cross breeding. However, since the tea tree genetic transformation system has not been successfully established, gene editing and precision breeding cannot be realized, and tea tree breeding still adopts the traditional hybridization screening mode. This requires long-term work accumulation of tea tree breeders and long-term observation of new strains, so that it is possible to breed a new tea tre...
