Abstract

A regulator for growing se-enriched tea leaves is prepared through fermenting pig dung and silkworm excrement, filtering, adding sodium selenate (or selenite) and dissolving. Its advantage is high Se content in tea leaf. It is applied through diluting and spraying it on buds of tea tree.

Description

a 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. Two technical background [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-gra...
