Abstract

The present invention discloses selenium-rich black peanut and its production process. The production process includes the following steps: measuring selenium content in soil, pH value of soil, heavy metal content in soil and water and selenium content in the air and water to determine the selenium and lime applying amount; soaking seed with selenium containing liquid, leaf spraying of selenium fertilizer, etc. to ensure the selenium content in peanut stably in 230-250 mcg / kg. The selenium-rich black peanut is good for health and has required heavy content without harm to human body.

Description

technical field [0001] The invention relates to a production method of crops rich in trace elements, in particular to a production method of selenium-enriched black peanuts and selenium-enriched black peanuts produced by the method. Background technique [0002] Selenium is an essential trace element for the human body. Selenium deficiency can cause many diseases, such as Keshan disease, diabetes, cardiovascular disease, etc., and cause low immunity. Both the World Health Organization in 1973 and the Chinese Nutrition Society in 1988 listed selenium as a trace element that the human body must supplement every day. The World Health Organization recommends that each person generally needs to supplement 40-100 μg per day, 50-200 μg in China, 60-150 μg in the United States, and 98-224 μg in Canada. Nutrition surveys in thirteen provinces and cities in my country show that the daily intake of selenium for adults is only 26.93 μg, which is far from the recommended standards of th...
