Embodiment 1

[0017] Embodiment 1: the preparation of organic selenium biological agent

[0018] Take 30g of selenium dioxide, 30g of sodium bicarbonate, 10g of methionine, 35g of brown sugar, 3g of urea, 3g of potassium dihydrogen phosphate, 2g of magnesium sulfate, 2g of manganese sulfate, 4g of calcium chloride, and 30mL of EM active bacteria. First add selenium dioxide into 5000g water and stir to dissolve, then add methionine, mix and dissolve, then add sodium bicarbonate, adjust the pH to 6.5-7.5, then add brown sugar, urea, potassium dihydrogen phosphate, magnesium sulfate, manganese sulfate, Calcium chloride, 6,500 grams of water and EM active bacteria are dissolved and then anaerobically fermented. The fermentation temperature is controlled at 20-25° C., and the time is controlled within 7 days to make an organic selenium biological agent.

Embodiment 2

[0019] Embodiment 2: the production of selenium-enriched tea.

[0020] The organic selenium biological agent prepared in Example 1 was diluted with water to 65 times of the original volume. At this time, the selenium content was 28.5 ppm. Utilize the spray tool to spray the diluted organic selenium biological agent on the leaf surface of the growing tea tree, so as to make it less dripping. Its consumption control is 20kg medicinal liquid / mu tea tree land. The distance between the front, back and left and right of each tea tree in each mu of tea field is not less than 50-60 cm. The application time is 30 days before picking, and it is sprayed once every 6 days on average, 5 times in total. During use, the outdoor temperature should be 10-15°C, and it should not be used in rainy days. If it rains suddenly after the spraying is over, the amount of spraying is the same as the previous time because it will be used again after the rain stops. After picking, the finished tea is ...

Abstract

The invention discloses a production method of selenium-rich tea. The production method comprises the following steps: diluting an organic selenium biological agent until the selenium content of the biological agent is 25-35ppm; and spraying the diluted organic selenium biological agent on the leaf surface of a tea tree with the spraying amount of 20-30kg / mu for five times and once every about six days at 30 days before tea leaves are harvested, wherein the organic selenium biological agent is prepared by mixing and fermenting selenium dioxide, sodium bicarbonate, methionine, brown sugar, urea, monopotassium phosphate and EM (effective microorganism), the weight ratio of selenium dioxide to sodium bicarbonate to methionine to urea to monopotassium phosphate is (25-35): (25-35): (8-10):(35-40): (1-8): (1-8), and the amount of the EM is 30-35mL / 25-35g of selenium dioxide. The production method disclosed by the invention is low in organic selenium biological agent cost, wide in raw material source, simple in preparation process and easy to grasp.

Description

technical field [0001] The invention relates to a production method of tea leaves. Specifically relates to a production method of selenium-enriched tea. Background technique [0002] Selenium is one of the essential trace elements for human beings. At present, scientific institutions and health organizations all over the world have unanimously recognized that there are eight undisputed essential trace elements for the human body: selenium, iron, manganese, copper, cobalt, zinc, molybdenum, and iodine. [0003] At present, there are more than 40 kinds of human diseases related to selenium deficiency, including cancer, cerebrovascular disease, diabetes, liver disease, thyroid hormone imbalance and so on. [0004] In 1973, the World Health Organization confirmed that the essential elements for the human body are: iron, selenium, copper, zinc, iodine, etc. If the human body wants to maintain the normal operation of life, it must absorb enough selenium from food. According to...
