Method for improving yield and quality of tea by means of adjusting illumination intensity

Abstract

The invention discloses a method for improving yield and quality of tea by means of adjusting illumination intensity. The method is characterized in that a light shading material is selected from a black HDPE (high-density polyethylene) sunshade screen which is widely applied to the market at present and is low in price; different illumination intensity of the tea garden is changed by means of building a sunshade awning above the border surface of a tea garden and covering the tea garden with the sunshade screen; the light shading degree of the sunshade screen is 26 percent to 65 percent, so that the environmental factors, such as illumination and temperature, of the tea garden are changed, the yield of dry matters of flowers and fruits of tea trees can be obviously reduced, the absorptive amount of the flowers and the fruits of the tea trees to nutrients, such as nitrogen, phosphorus and potassium, is reduced, the tea yield is increased, the amino acid content of the tea is increased, the phenol-ammonia ratio of the tea is reduced, and the tea quality is improved. The method disclosed by the invention has the advantages that the effects of higher safety and higher environmental friendliness to a tea product and a tea garden environment are achieved, and the labor cost can be greatly reduced; the effects of simplicity and convenience in operation and easiness in learning and understanding are achieved, the effect of controlling the blooming and fruit bearing of the tea trees is obvious, and the method is more suitable for extensive popularization and application.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for reducing the formation of flowers and fruits of tea trees and improving the yield and quality of tea leaves by adjusting light intensity. Background technique [0002] The main purpose of cultivating tea trees is to harvest more tender shoots and leaves. People hope that their vegetative growth will be vigorous, so as to pick more teas and pick good teas. But the flower buds of tea trees begin to differentiate in May every year, and bloom one after another from October to December or even January of the next year. It takes a year and a half for the fruit to mature, and there are a lot of them. According to the survey, picking tender tea fruit in May every year can reach 1500kg / hm 2 Above, especially the flowering volume is greater. These camellias and tea fruit consume a large amount of nutrients in the tea garden every year, thereby weakening the vegetative...
