Description
Technical field
The present invention relates to production technology of crops field, specially a kind of method that can promote crop selenium-rich.
Background technique
Se-rich farm products are the agricultural product for containing abundant selenium element.Selenium is a kind of chemical element, and chemical symbol is Se, a kind of
It is nonmetallic.It may be used as nutrient necessary to light-sensitive material, electrolytic manganese industry catalyst, animal body and the beneficial nutrition of plant
Element etc..Selenium is also the essential trace elements of the human body.Selenium participates in a variety of selenoenzymes and Selenonic protein in synthesized human.Wherein paddy Guang
Sweet peptide peroxidase is catalyzed hydroperoxides in vivo or lipid peroxide is changed into water or various alcohols, eliminates
Attack of the free radical to biomembrane, protects biomembrane from oxidative damage；Selenium participates in constituting the de- iodine enzyme of iodate thyroid gland amino acid.Selenium
Therefore " king of anti-cancer " being referred to as by scientist in body trace element.Selenium is required in people, animal, fowl and other animal bodies
One of microelement, according to modern medicine study, the heart of selenium and people, liver, brain, the activity of pancreas and immune system are closely related,
The long-term selenium deficiency of human body or low selenium can cause more than 40 kinds of diseases, including threaten maximum cancer to human health, and disease incidence is higher
Cardiovascular and cerebrovascular disease, it is difficult to which the diabetes of healing, the endemic diseases such as gram heart trouble and hypertension, anaemia, cataract etc., livestock and poultry lack
Selenium or low selenium can cause white muscle disease, lead to large quantities of death.However, in global most area, as people and other animals
Selenium deficiency in the food and drinking-water in body selenium element source.According to statistics, a countries and regions selenium deficiency more than 40 in the world, and China has 72%
Area selenium deficiency, China there are about 300,000,000 people by the threat of selenium deficiency or low selenium.Occur various selenium-rich currently on the market
Food and beverage, such as selenium wine, selenium salt, selenium beer, selenium oral solution, the common disadvantage of these products are need to add selenium compound
Additive, it is difficult to it is uniformly mixed, especially has the product of adherence to flours, and expensive, and be inorganic selenium mostly,
It is also easy to produce toxicity, absorptivity is low, in animal husbandry, sodium selenite is usually added in feed, but dosage is not easy to grasp, excessive to hold
Easily livestock and poultry is caused to be poisoned, excessively few not have selenium-supply effect then, animal is low to sodium selenite absorptivity, inconvenient to use, the present invention
The shortcomings that being to overcome the above-mentioned prior art and directly improve the farming produce as human food and animal husbandry feed resource
A kind of method of Se content in product, keeps the selenium-supply process of the mankind and animal husbandry safer, simple and easy to do.
So how to design a kind of method that can promote crop selenium-rich, becoming us will currently be solved the problems, such as.
Summary of the invention
The purpose of the present invention is to provide a kind of methods that can promote crop selenium-rich, to solve to propose in above-mentioned background technique
