Problems solved by technology

Sodium selenate and sodium selenite can be absorbed by the human body, but the range between the nutritional dose and the toxic dose of these inorganic selenium salts is very narrow. Eating a large amount of vegetables and fruits that have been fertilized with selenium may cause selenium poisoning, because inorganic selenium Salt is highly toxic, and many countries have banned adding it to food and feed

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the examples, but the embodiments of the invention are not limited thereto.

[0021] Embodiment A kind of nano selenium compound fertilizer of the present invention

[0022] Preparation of Glycine-modified Selenium Nanoparticles

[0023] 1) Weigh 230g of vitamin C and 750g of glycine, put them into a FS1000y-3 high-speed pulverizer, mix and pulverize for 5 minutes.

[0024] 2) Weigh 23g of sodium selenite, add it to the mixture of vitamin C and glycine, react in solid phase under high-speed collision and shear state for 3-10 minutes, sodium selenite is reduced to nano-state red zero-valent selenium, And it is modified and protected by glycine to maintain the nano state, and the content of glycine-modified nano-selenium selenium is 1000mg / kg.

[0025] Preparation of Nano Selenium Compound Fertilizer

[0026] Weigh 50 g of glycine nano-selenium with a selenium content of 1000 mg / kg, and...

Abstract

The invention relates to a nano-selenium compound fertilizer which is characterized by comprising the following steps of: a, preparing glycine modified nano-selenium; and b, preparing the nano-selenium compound fertilizer. The nano-selenium compound fertilizer is prepared by nanoscale red zero-valent selenium by a biological or chemical method, and the nanoscale zero-valent selenium is dissolved in water so as to form bright red transparent solution. The nano-selenium has strong biological activity and very high safety; and compared with inorganic selenium salt, the nano-selenium has the characteristics of low toxicity and high efficiency for which people hope best of all.

Description

technical field [0001] The invention relates to a nano-selenium compound fertilizer. Background technique [0002] Selenium is an essential mineral element to maintain human health. Insufficient selenium intake can easily cause various diseases. Selenium can resist free radicals, improve immunity, and protect the human body against foreign harmful substances. Selenium has a variety of immune and biological functions on human health, especially the prevention of cardiovascular disease, anti-tumor, anti-virus and anti-aging effects. Selenium is The active center of a variety of enzymes plays a role in resisting diseases, preventing aging, and enhancing immune function in life activities, so as to maintain the best state of body functions. [0003] Selenium is used in health care, anti-oxidation and anti-aging, scavenging free radicals, protecting cell membranes, protecting the heart and liver, regulating heart rate, preventing liver cirrhosis, preventing cancer and anti-cance...
