Description
Technical field
The present invention relates to a kind of nanometer selenium composite fertilizer.
Background technology
Selenium is the mineral element of keeping necessity of HUMAN HEALTH, and selenium picked-up deficiency causes multiple disease easily.Selenium can be resisted radical, improves immunizing power, and the protection human body is resisted external objectionable impurities; Selenium has panimmunity and biological function to HUMAN HEALTH, and especially Prevention of Cardiovascular is sick, and is antitumor; Antagonism virus and the anti-ageing effect of waiting for a long time; Selenium is the active site of plurality of enzymes, in vital movement, plays and resists disease, prevents aging, the effect of raise immunity, thereby make body function keep optimum regime.
Selenium is in health care, and resisting oxidation and delaying senility is removed radical, and the protection cytolemma is protected the heart and protected liver; Regulate heart rate, the prevention liver cirrhosis, cancer-resisting prevents coronary heart disease, reduces serum total cholesterol; Vision protection is prevented and treated cataract, and dispelling toxicity, detoxicating is eliminated harmful heavy metals such as mercury, tin, cadmium, lead in the body; Prevent and treat mellitus, the oxidation of prevention beta Cell of islet destroys, and lowering blood glucose and glucose in urine improve diabetic subject's symptom and all have vital role.
Yet the content of selenium in the earth's crust is very rare, and it is extremely uneven to distribute again; The whole world has more than 40 state to belong to low selenium and scarce selenium area, and China is a scarce selenium big country, and investigation shows; Except indivedual counties, Ziyang, Shaanxi and enshi city are the high selenium area; Low selenium in the county (city) in the whole nation 72% or scarce selenium area, the intravital selenium of people is mainly derived from plant food, and the selenium content in the plant is decided by the selenium content in the local water and soil; Ambient soil lacks selenium and causes the vegetable food selenium content on the low side, lacks selenium thereby cause human body.Be grown up and need take in 50 micrograms normal every day, China overwhelming majority area surpasses the selenium wretched insufficiencies that 700,000,000 populations obtain from food, and it is to be related to the healthy major issue of hundreds of millions of Chinese people that human body is mended selenium, and in safety and suitable scope, it is very urgent that science is mended selenium.
The intravital selenium of people is mainly derived from plant foods such as wheat, rice, corn, potato class, vegetables, Selenium rich melon fruit; And the selenium content in the water and soil is determining the selenium content of plant; Apply and contain selenium fertilizer and replenish selenium content in the water and soil or, absorb in the plant, become organoselenium through bio-transformation containing on the base of leaf that selenium fertilizer directly sprays application to crop; Making people from food, absorb enough selemium nutritions, is most economical, safety and the most effectively mend the selenium method.
In order to produce Se-rich farm products, in the preparation method of various Se-rich farm products and selenium fertilizer, the common trait of prior art all is to use sodium selenate or Sodium Selenite.Sodium selenate and sodium selenite solution are through soil irrigation or foliage-spray, and the plant absorbing rear section is converted into organoselenium, but unconverted inorganic selenium accounts for 40-60% in the plant, and vegetables, melon and fruit, the inorganic selenium content of especially lacking vegetative period are higher.Sodium selenate and Sodium Selenite can be absorbed by the body; But the nutrition dosage of these inorganic selenium salt and the narrow range between the toxicity dose; A large amount of edible fertile vegetable melon and fruits of selenium of executing may cause selenosis, because the toxicity of inorganic selenium salt is big, a lot of countries have forbidden in food and feed, adding.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, the preparation method of the nanometer selenium composite fertilizer of a kind of efficient, low toxicity, safety is provided.
A kind of nanometer selenium of the present invention composite fertilizer is characterized in that comprising following operation steps:
A, preparation glycocoll decorated nanometer selenium
Get vitamins C 100g-300g and glycocoll 200g-800g, mix with high speed disintegrator and pulverized 3-10 minute; Sodium Selenite 10g-30g is joined in the mixture of vitamins C and glycocoll; Collision in high speed disintegrator again, shearing solid state reaction 3 minutes-10 minutes; Sodium Selenite is reduced to the red zeroth order selenium of nanometer fineness by vitamins C, and by the glycocoll modification protection, obtains glycocoll decorated nanometer selenium;
B, preparation of nano selenium composite fertilizer
Get red glycine nano-selenium 5g-50g and primary ammonium phosphate 995g-950g, pulverize mix selenium content be the nanometer selenium composite fertilizer of 50-500mg/kg.
Nanometer selenium of the present invention composite fertilizer is characterized in that comprising following operation steps:
A, preparation glycocoll decorated nanometer selenium
Get Catergen 30g and glycocoll 750g, mix with FS1000y-3 type high speed disintegrator and pulverized 5 minutes; Sodium Selenite 23 grams are joined in the mixture of vitamins C and glycocoll; Collision in high speed disintegrator again, shearing solid state reaction 3-10 minute; Sodium Selenite is reduced to the red zeroth order selenium of nanometer fineness by vitamins C, and by the glycocoll modification protection, obtains glycocoll decorated nanometer selenium;
B, preparation of nano selenium composite fertilizer
Get red glycine nano-selenium 50g and primary ammonium phosphate 950g, pulverize mix selenium content be the nanometer selenium composite fertilizer of 500mg/kg.
A kind of nanometer selenium of the present invention composite fertilizer prepares nano level red zeroth order selenium with the biological or chemical method, the nanoscale zero-valent selenium red clear solution that becomes clear that is soluble in water.Nanometer selenium has very strong biological activity, simultaneously has very high security again, compares with inorganic selenium salt, and nanometer selenium has low toxicity that people hope to obtain most characteristic efficiently.Detect and show the CDC Ins of Nutrition & Food Hygiene, compares with selenium yeast with Sodium Selenite, and the acute toxicity of Sodium Selenite is about 7-22 times of nanometer selenium.The acute toxicity of selenium yeast is about 4-22 times of nanometer selenium.Plant is used nanometer selenium composite fertilizer, the unconverted zeroth order nanometer selenium of part, and human body is taken in the same biologically active in back, has avoided the toxic side effect of selenium again.
1 kilogram of nanometer selenium composite fertilizer was dissolved into irrigated crop or foliage-spray in the 50-100 kg of water when a kind of nanometer selenium of the present invention composite fertilizer used; Become organoselenium through bio-transformation after the plant absorbing; Unconverted zeroth order nanometer selenium can be absorption of human body in the plant, has no side effect.
