Biological selenium-rich fertilizer agent and preparation method thereof

Abstract

The invention relates to the technical field of fertilizer, in particular to a biological selenium-rich fertilizer agent and a preparation method thereof, specifically a selenium-rich fertilizer agent of modified rare earths containing sodium selenite and complex rare earths. The biological selenium-rich fertilizer agent is prepared from the following raw materials proportioning according to parts by weight, wherein the ratio of sodium selenite to complex rare earths is 10-20 to 80-90. The invention has scientific and reasonable prescription, simple and convenient production and use methods, low cost, safe and efficient performances. Tests show that the sodium selenite is absorbed, transferred and synthesized through crops, and most selenium is enriched in the rootstock, branches and leaves and fruits of the crops as organic compounds containing selenomethionine. The content of biologically organic selenium in the fruits or vegetable of the crops can be increased by 5-20 times, thereby increasing the contents of various amino acids, improving the yield, quality and disease resistance of crops. Selenium required to human body can be complemented by having selenium-rich farm products so as to prevent diseases, strengthen the body and have good health and long life. The biological selenium-rich fertilizer agent and the preparation method thereof is applied to popularizing and applying in broad rural areas, and have considerable market foreground.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a biological selenium-enriched fertilizer and a preparation method thereof, specifically a sodium selenite-containing (Na 2 SeO 3 ) and the selenium-enriched fertilizer of the complexed rare earth, that is, the modified rare earth. Background technique [0002] Human beings have entered the 21st century, and China has initially achieved a moderately prosperous life. While improving their living standards, people pay more attention to the exploration of life sciences in order to live a long and healthy life. Modern science has discovered that selenium (Se) is one of the essential life elements for the human body. In medicine, it not only has the value of treating diseases, but also has the effect of preventing diseases and strengthening the body. Selenium is an indispensable trace element for the human body to maintain normal life activities. It directly participates in the ...
