Abstract
The invention relates to a method for preparing a nano-selenium leaf fertilizer through utilizing sodium dithionite as a reducing agent. The method has the advantages of quick reaction, easiness in implementation and low cost. The nano-selenium leaf fertilizer is prepared according to the following steps: mixing nano-selenium with biogel with strong adhesiveness to form a solution, wherein the content of nano-selenium is 5.0%-10%; and reacting a selenium source reactant with a reducing agent and the biogel, reducing and dispersing.
Description
Technical field
The present invention relates to a kind of foliage fertilizer, specifically a kind of nanometer selenium foliage fertilizer and preparation method thereof.
Background technology
Nineteen fifty-seven, the Schwarz of Germany and Foliz have delivered the report that selenium has the Animal nutrition effect first, from then on the selenium element is more and more paid attention to the importance of HUMAN HEALTH after, and up to 1973, the World Health Organization formally was the trace element of needed by human with the selenium element column.Selenium is most important to HUMAN HEALTH; it is the moiety of human erythrocyte Selenoperoxidase and phosphatide hydrogen peroxide Selenoperoxidase; it mainly acts on is participate in the body endoenzyme synthetic; structure and the function of protection cytolemma exempt from over oxidation and interference, have many important physical functions.Mending selenium by body can antiviral, anti-ageing, anticancer change, anti-cell increases, preventing from heavy metal is poisoned, aspergillus flavus-resistance mycin and carcinogenesises such as benzanthrene and nitrosamine, reduces the generation of more than 40 kind of diseases such as hypertension, cardiovascular and cerebrovascular disease, diabetes, hepatitis.
The standard that world selenium association is recommended is to take in selenium 60 μ g/d per capita, the nutrition survey report that Chinese Soclety of Nutrition does shows, China adult takes the photograph selenium quantity not sufficient 27 μ g/d, and its reason is that soil, the water source in life area lacks selenium, causes in the food crop selenium content low.According to investigations, lack nearly 22 in selenium province in China, have 72% soil to be in various degree scarce selenium district, about 100,000,000 populations lack selenium.Increasing rich selenium food crop production is to realize mending the safe and effective approach of selenium, and therefore, the exploitation selenium-enriched fertilizer is the prerequisite that obtains rich selenium grain.
The nanometer selenium foliage fertilizer of Shi Yonging is that rich selenium effect is best in the market.Many pieces of patent disclosures the preparation method of nanometer selenium, yet in open preparation method, great majority are to be that selenium sources such as reductive agent and Sodium Selenite or sodium selenate react with the vitamins C, as CN1789113, CN1947723, CN101558826 etc.The difficult generation of this method existence reaction, the shortcoming that the vitamins C consumption is big, cost is high.
Summary of the invention
The present invention is directed to above deficiency, having invented a kind of is the method that reductive agent prepares nanometer selenium fertilizer with the vat powder, has to be swift in response, to implement the advantage easy, that cost is low.Following feature is arranged specifically:
1, foliage fertilizer is by the strong xanthan gum wiring solution-forming of nanometer selenium and binding property, and the content 5.0%-10% of nanometer selenium, xanthan gum content are 10%-20%, and rest part is water.
2, described nanometer selenium is by selenium source reactant and reductive agent and xanthan gum reaction, through reduction, dispersion preparation.
3, a kind of nanometer selenium foliage fertilizer according to claim 2 and preparation method thereof is characterized in that: described selenium source is Sodium Selenite, sodium selenate or tin anhydride.
4, a kind of nanometer selenium foliage fertilizer according to claim 2 and preparation method thereof is characterized in that: described reductive agent is vat powder.
5, a kind of nanometer selenium foliage fertilizer according to claim 2 and preparation method thereof is characterized in that: described reaction, the mol ratio of selenium source and reductive agent are 1: 1-3.
6, a kind of nanometer selenium foliage fertilizer according to claim 2 and preparation method thereof is characterized in that: temperature of reaction is 0-80 ℃; Reaction times is 1-6 hour.
7, a kind of nanometer selenium foliage fertilizer according to claim 1 and preparation method thereof is characterized in that: described xanthan gum is gum arabic, algin, carrageenin, its first-selected gum arabic, and effect is dispersion, stable nanoparticles.
Embodiment
The specific embodiment of below enumerating is further detailed the present invention, does not represent protection scope of the present invention.What particularly point out is, if still belong to the scope of protection of the invention according to the change of the prompting non-intrinsically safe of making of the present invention.
