Planting method for selenium-rich garlic

Abstract

The invention provides a method for cultivating a selenium-rich garlic plant material. In the selenium-rich garlic plant material, the content of selenium is 1mg / kg to 2000 mg / kg, and the selenium existed in a form of Se-methylselenocysteine accounts for not less than 85% of the total content of the selenium. The planting method is characterized by comprising a combined method of soaking a variety of garlic with a self-made selenium-contained regulation liquid and adding a selenium-rich fertilizer into a garlic growth medium in garlic growing process. According to the invention, the above-mentioned method can provide stable and effective selenium source supply for the variety of garlic, promotes the garlic to absorb and accumulate the selenium, realizes effective transfer of the selenium to the garlic, and avoids a poisonous risk on a garlic growth environment due to excessive selenium; meanwhile, through the addition of selenium-contained biomacromolecules, the transfer of inorganic selenium to organic selenium is more thoroughly and more efficient; loss and waste of the selenium are avoided; and selenium content in a final garlic product can be guaranteed.

Description

technical field [0001] The invention relates to a method for planting selenium-enriched garlic, which belongs to the field of agricultural production. Background technique [0002] As a special vegetable, garlic contains more than 100 medicinal and health-care ingredients, including 43 sulfur-containing volatiles, 13 sulfur sulfinate esters, 9 amino acids, 8 peptides, 12 glycosides, and 11 enzymes. kind. Therefore, garlic not only has high nutritional value, but also has bactericidal, antibacterial, blood pressure-lowering, anti-aging and anti-cancer effects. [0003] Selenium is one of the essential trace elements for the human body. Insufficient or excessive intake can cause diseases. In the 1970s in my country, it was discovered that Keshan disease and Kaschin-Beck disease were related to selenium deficiency. With the deepening of selenium research, people realized that many diseases such as cancer, cardiovascular and cerebrovascular diseases, diabetes, human immunity d...

However, this method uses a large amount of sodium selenite or sodium selenate in the field and under hydroponic conditions without any solution for controlled release and residual selenium, so the large amount of sodium selenite or sodium selenate used may Diffusion into the environment or residues in the original culture medium cause selenium pollution risks to the soil
