Abstract
The invention discloses high-selenium wheat. According to the high-selenium wheat, 5-150mg/kg of selenium and organic selenium being more than or equal to 70% are contained in the grains of wheat. The invention also discloses a production method of the high-selenium wheat, which is as follows: the high-selenium wheat is obtained by applying 15-30kg of nano selenium plant nutrient agents in each mu of soil during the sowing period, the wintering period, the period of seedling establishment, the elongation period and the pustulation period. The nano selenium plant nutrient agents are produced by Suzou SeTek Technology Co. Ltd. According to the high-selenium wheat, the selenium content is extremely high, the selenium mainly exists in an organic selenium form so as to be beneficial to the absorption of people or animals, the standardization of the selenium content is high, the demands of industrial production can be met, and the selenium content in a preliminarily processed product is stable.
Description
Technical field
The present invention relates to a kind of high selenium wheat and production method thereof, belong to functional food research and development technology field.
Background technology
Wheat (wheat) is a kind of the extensive gramineous plants of plantation all over the world, and wheat is the cereal crops of gross yield second in the world, is only second to corn.Wheat is rich in starch, protein, fat, mineral matter, calcium, iron, thiamine, vitamin b3, nicotinic acid and vitamin A etc., is one of common food of humans and animals.
The Se content of common wheat according to areal variation generally between 10-30ug/kg; The Se-rich wheat major part that occurs in the market is that the page sprays technology or directly soaks (like the Chinese CN 101897266A) of the technology acquisition of seed with rich selenium solution; Its Se content major part is all between 100-400ug/kg, and this method very easily causes toxic action to wheat, and inorganic selenium is residual big; Have necessarily can toxicity; Its purposes mainly is to make selenium rich noodles or make Se-enriched feedstuff etc. as raw material, but owing to technical reason, the highest 2000ug/kg of being no more than of Se content in the Se-rich wheat that this kind technology is produced; Technology has bigger breakthrough at present; Its direct result is to cause Se-rich wheat usage amount aborning bigger, and therefore cost increases, because also there is inconvenience greatly in consumption in the use of reality.So the wheat of a kind of high Se content of market active demand, it can be used as additive and is blended in products such as making selenium rich noodles or Se-enriched feedstuff in common wheat or the normal diet, and usage amount sharply descends, and cost significantly reduces.
Summary of the invention
The objective of the invention is: a kind of high selenium wheat is provided, has solved problems such as Se content is lower in the Se-rich wheat that occurs in the market, consumption is big, expense is high, use inconvenience.
Another object of the present invention provides the production method of high selenium wheat.
In order to solve these problems of the prior art, technical scheme provided by the invention is:
A kind of high selenium wheat is characterized in that Se content in the described high selenium wheat is between 5-150mg/kg.
Preferably, organic selenium content ratio >=70% in the said high selenium wheat.
Preferably, the Se content of said high selenium wheat is between 20-100mg/kg, and organic selenium content ratio >=70%, and organic selenium wherein mainly exists with the selenomethionine form.
Preferably, described high selenium wheat is to obtain through sowing time, the phase of surviving the winter, period of seedling establishment, shooting stage and pustulation period every mu of nanometer selenium plant nutrient agent that spreads fertilizer over the fields the 15-30 kilogram at wheat.
Preferably, described high selenium wheat is through obtaining at the shooting stage of wheat every mu of nanometer selenium plant nutrient agent that spreads fertilizer over the fields the 15-30 kilogram.
Preferably, described high selenium wheat is through at the shooting stage of wheat every mu of nanometer selenium plant nutrient agent that spreads fertilizer over the fields the 15-30 kilogram, and once mends during the phase at wheat grain filling and to execute the nanometer selenium plant nutrient agent and obtain (pustulation period fertilising except).
Preferably, the production method of described high selenium wheat is after using the nanometer selenium plant nutrient agent, wheat to be carried out once suitable irrigation to handle at every turn.
The production method of high selenium wheat provided by the invention mainly may further comprise the steps:
1. use the nanometer selenium plant nutrient agent at sowing stage of wheat: before wheat cultivation; (Suzhou selenium paddy Science and Technology Ltd. produces with the nanometer selenium plant nutrient agent; Product type XJCP002) applying Tanaka as base manure with the consumption of every mu of 15-30 kilogram (can use separately; Also can behind the base manure mixing, use), carry out rotary tillage and sowing then; Perhaps carry out disposable sowing in the machine with broadcasting,, carry out once suitable irrigation and handle if soil moisture content is lower behind the seeding and fertilizing with together joining seed manure behind nanometer selenium plant nutrient agent and the base manure mixing;
2. sowing stage of wheat is used the nanometer selenium plant nutrient agent later on: if wheat is sowed; Can be respectively at the phase of surviving the winter, the period of seedling establishment of wheat; Shooting stage and pustulation period spread fertilizer over the fields; Mu is used nanometer selenium plant nutrient agent 15-30 kilogram, and the fertilising back is lower like soil moisture content, should carry out once suitable irrigation and handle.Note during fertilising spreading fertilizer over the fields evenly, irrigation is the mode that preferably adopts sprinkling irrigation, can with stick on the wheat blade face the nanometer selenium plant nutrient agent together leaching to wheat root, the utilization ratio of increase nanometer selenium plant nutrient agent;
3. mend and execute: in pustulation period of wheat wheat is once mended and executed the nanometer selenium plant nutrient agent and handle (pustulation period fertilising except);
4. gather in the crops: after treating high selenium harvesting wheat, with carrying out abundant mixing in the high selenium wheat adding mixing machine, to obtain the higher high selenium wheat of standardization level;
5. selected impurity elimination: the high selenium wheat that will fully mix is removed unnecessary not plump wheat, impurity and unsound grain through the selected impurity elimination of cleaner;
6 packings: the high selenium wheat after selected is good with the woven bag quantitative package of good permeability, keep high selenium wheat water content not to be higher than 12%, but long preservation.
High selenium wheat Se content provided by the invention is high, and selenium is that main memory exists with the organic selenium form, helps the absorption of human body or animal more, and because Se content is high, usage amount is few, can reduce cost greatly.
With respect to scheme of the prior art, advantage of the present invention is:
1, a kind of high selenium wheat provided by the invention, its consumption in practical application is less, can save cost greatly and practice thrift producing cost;
2, a kind of high selenium wheat provided by the invention is root system conversion and the absorption selenium element through plant, convert inorganic selenium to organic selenium, so its organic selenium content is high, will get well than the rich selenium security of products that traditional approach obtains;
3, a kind of high selenium wheat provided by the invention, its Se content standardization is higher, can satisfy the demand that batch production is produced, and the Se content in its preliminary working product is stable.
