Selenium-enriched tea production regulator and use method thereof

Abstract

The invention discloses a selenium-enriched tea production regulator and a production method thereof, and belongs to high-quality tea production methods. Water is added to ferment pig manure and silkworm excrement, fermented products are filtered by 100-200 meshes, sodium selenite or sodium selenate is added, the fermented products are dissolved to obtain the selenium-enriched tea production regulator, and the concentration of the selenium-enriched tea production regulator is 100-200gL-1 by selenium. In a tea tree germination period, 400-500 times of water is added to dilute 100ml of the selenium-enriched tea production regulator per mu of tea gardens, and then the selenium-enriched tea production regulator is sprayed. The selenium content of tea is higher than 1.0mgkg-1, organic seleniumaccounts for 80% or more of total selenium in the tea, and the sensory quality, the chemical quality and the healthcare function of the tea are improved. The selenium-enriched tea production regulatoris applicable to selenium-deficient or low-selenium areas in China and provides enough dietary selenium nutrition for residents in poor-selenium and selenium-deficient areas.

Description

technical field [0001] The invention discloses a production regulator of selenium-enriched tea and its usage, which belongs to tea production technology and is specially used for the production of high-quality selenium-enriched tea. Background technique [0002] Tea is a traditional export commodity in my country, and tea production is also a traditional advantageous industry. It has always been one of the pillar industries for tea farmers in hilly and mountainous areas to get rid of poverty and increase local fiscal revenue. At present, the excessive use of chemical fertilizers, pesticides, herbicides and other man-made measures in tea production has caused pesticide residues in tea products, the flavor of tea products has declined, and consumers' health has been endangered. It is also a major issue in tea foreign trade. Outstanding issue. The products are single and low-grade. The tea produced is basically a primary product, and the added value of middle and low-grade tea...
