Multiple microbial manure applied in summer to increase quality of black tea and preparation method thereof

Abstract

The invention discloses a multiple microbial manure applied in summer to increase quality of black tea. The microbial manure is fermented from the following raw materials by weight: amino selenium or / and amino zinc, a water-soluble carbon source and nitrogen source, and a mixed microbial solution of Bacillus subtilis and VA mycorrhizal fungi. According to analysis, the multiple microbial manure contains a large amount of enzymes (alpha-amylase, neutral protease) required for physiological and biochemical reactions during growth and development of tea tree, biotin, interferon, amino acids and other factors beneficial for life activity. These factors ensure strong growth of tea plants in summer, and resist disease, insect and drought, and realize strong root absorption function, high photosynthetic efficiency, UV resistance, resistance to formation and accumulation of anthocyanin in fresh leaves, so as to improve the quality of black tea.

Description

technical field [0001] The invention belongs to a fertilizer, in particular to a special fertilizer for improving the quality of black tea. technical background [0002] Green tea is mostly made by picking fresh leaves in spring. In summer, due to the high temperature and the enhancement of the sun's ultraviolet rays, the anthocyanins in the fresh leaves of tea trees are accumulated, resulting in aggravated bitterness and astringency, which seriously affects the quality of green tea and cannot be picked and processed. However, in order to increase the tea production of tea gardens and increase the economic benefits of tea areas, fresh leaves in summer and autumn are often picked and fermented to make black tea. However, there are only three tea tree varieties that are really suitable for making high-grade black tea. In my country, there are only three unique varieties of Fujian Wuyi Lapsang Souchong, Yunnan Dayezhong and Huangshan Qimen Xiaoyezhong. The tea areas not of th...

Problems solved by technology

In areas other than this type of tea, it is often unsuitable to produce black tea or it is difficult to produce high-grade black tea because of severe anthocyanin accumulation in summer and autumn fresh leaves and aggravated bitterness.

If forced production is avoided, the quality of the product will be poor and the benefit will be poor, and the production of black tea will not be worth the cost.
