Description
Technical field
The present invention relates to Selenium in Soil element activators, and in particular to a kind of mixed type nanometer Selenium in Soil element activator and its preparation
Method.
Background technique
Selenium is micronutrient element needed by human, has anticancer, improves a variety of effects such as immunity, anti-aging, tool
There are the laudatory titles such as " Promethean fire ", " king of anticancer ".The whole world has a countries and regions selenium deficiency, China more than 40 to have 2/3rds ground
Area belongs to Selenium deficiency area, wherein 30% is serious selenium deficiency area.It is 50-200 μ g/d that human body selenium intake is recommended by Chinese Soclety of Nutrition, and
Only 26-32 μ g/d, selenium intake are seriously relatively low for China's city dweller's intake.The distribution of global soil selenium element is extremely uneven, Guangxi
It is China's only a few selenium-enriched area, only just up to 2,120,000 hectares of Gulf Area selenium-rich soil area are current regionals
The maximum area drawn a circle to approve out of Geochemistry investigation work selenium-rich soil region in flakes.Inorganic selenium is converted to organic selenium using plant,
Selenium In Foods content is improved, is the fundamental way for improving human body selemium nutrition.
In China, the research and development of Se-rich farm products is also in primary developing stage, and there are also most of food not
Carry out selenium-rich metaplasia to produce and develop, selenium-rich industry has a extensive future.Agricultural product selenium-rich mainly has natural selenium-rich and artificial richness at present
Selenium two ways.Wherein, natural selenium-rich refers to that crop absorbs the Available Selenium element in soil and reaches selenium-rich standard, but natural
Selenium-rich is limited by Se content natural in nature and soil physico-chemical property.Soil physico-chemical property influences selenium in the soil
Existing forms, to influence absorption of the crop to soil natural selenium element.
Guangxi selenium-rich soil area is current Chinese multiple target regional geochemistry investigation work up to more than 2.12 ten thousand square kilometres
The maximum area drawn a circle to approve out selenium-rich soil in flakes.But equally exist the quagmire of agricultural product " good few, more bad ".It is main
Wanting reason is that Selenium in Soil element full dose content is high, but the overwhelming majority is mineral state, and plant cannot directly be absorbed and utilized.Therefore, having must
Designing one kind can make soil chats states of matter selenium Selenium in Soil element activator carry out activating soil selenium element.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of mixed type nanometer Selenium in Soil element activator and preparation method thereof,
The pH value of soil is adjusted in the mixed type nanometer Selenium in Soil element activator as made from the method for the invention, increases organic matter and contains
