Description
Technical field
The invention belongs to fertilizer preparation fields, more particularly, to a kind of nano selenium fertilizer feed additives and preparation method thereof.
Background technique
Selenium is the essential trace elements of the human body, is the activated centre of a variety of enzymes in human body, played in life resist disease,
It delays senescence, the effect of enhancing immune function.Selenium has protect liver, anticancer, protection angiocarpy, adjusts hormone secretion, an antagonism huge sum of money
Category, treatment cataract, removes many biological effects such as superfluous free radical at chemoradiation therapy.Selenium product is in health food and medicine
It is occupied an important position in product.
Selenium is not only beneficial to human body, and selenium is also a kind of beneficial element needed for plant growth, and selenium can stimulate the growth of plant
Root activity is sprouted and is improved in development, seed, promotes absorption and the plant metabolism of nutrition, improves photosynthesis and chlorophyll
Content enhances plant biological antioxidation and the resistance to environment-stress, improves the disease-resistant anti-adversity ability of crops, and have
The effect of antagonism heavy metal.The selenium content of agricultural product can be significantly improved after application selenium fertilizer, to greatly improve commodity value.It is existing
Selenium fertilizer in technology is mostly solid matter, is usually mixed with sodium selenite with organic matters such as animal wastes and/or plant defoliation
Compost maturity forms afterwards, or the organic selenium fertilizer prepared by modern biotechnology is directly added shape after auxiliary agent and water
At selenium-rich liquid manure.Both the above method is disadvantageous in that: selenium element in existing fertilizer without effective absorption carrier,
On the one hand there is no slow release effect, just selenium concentration is higher when application, and plant suction speed is limited, after on the other hand applying, in rainwater
And be easy to run off or fail under the effect of the natural conditions such as sunshine wind, the absorption efficiency of plant is not high.In addition, it should be noted that
Nanometer selenium on ordinary meaning, which refers to, to be restored elemental selenium from selenium salt by chemical reduction method and makes selenium by physical means
Reach nano-scale, the nanometer selenium in this meaning reaction condition and relevant device are required it is relatively high, production cost also compared with
Height, but obtained nanometer selenium is still inorganic selenium, and human body can absorb the inorganic selenium of a certain amount of such form and plays a role in health care,
But dosage wants strict control in order to avoid selenosis, while this nanometer selenium can not be also absorbed by plants.Therefore, applicant considers nothing
Machine selenium is prepared into a nanometer selenium solution, can overcome many deficiencies of selenium-enriched fertilizer in the prior art.
Summary of the invention
In view of this, the present invention is directed to propose a kind of nano selenium fertilizer feed additives and preparation method thereof, prepared by inorganic selenium
At nanometer selenium solution, many deficiencies of selenium-enriched fertilizer in the prior art can be overcome.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of nano selenium fertilizer feed additives, by each material composition of following mass percent: nanometer selenium 64.8%, biology are more
Sugar 35.2%, water, surplus.
Further, the nanometer selenium partial size is 30-300nm.
Further, a kind of preparation method of nano selenium fertilizer feed additives, includes the following steps:
(1) sodium selenite and sodium ascorbate are made into the solution of 100mM with distilled water, for use；
(2) 500mg biological polyoses are substantially soluble in 100ml distilled water；Under the conditions of nitrogen protection, 1ml sodium selenite is taken
Solution injects in reaction solution, stirs 10 minutes；
(3) 5ml sodium ascorbate solution is taken to be also injected into reaction solution, the reaction was continued at room temperature 48 hours；
(4) solution becomes red cloudy state from colorless and transparent state；It places reaction liquid into bag filter, dialyses two days,
Water is often changed, until outer aqueous solution is without free plasma selenium；The plasma selenium concentration in the nanometer selenium solution in bag filter is measured simultaneously,
It is settled to 1mM concentration.
Further, the nanometer selenium solution for preparing completion need to be protected from light, empty avoiding gas saves.
Compared with the existing technology, a kind of nano selenium fertilizer feed additives of the present invention and preparation method thereof have following excellent
Gesture:
It is of the present invention that inorganic selenium is prepared into a nanometer selenium solution, all of selenium-enriched fertilizer in the prior art can be overcome
It is mostly insufficient.
