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 [0001] The invention relates to a foliage fertilizer, in particular to a nano-selenium foliage fertilizer and a preparation method thereof. Background technique [0002] In 1957, Schwarz and Foliz of Germany published the report that selenium has animal nutrition for the first time. Since then, the importance of selenium to human health has been paid more and more attention. Until 1973, the World Health Organization officially listed selenium as essential for human body. trace elements. Selenium is very important to human health. It is a component of human erythrocyte glutathione peroxidase and phospholipid hydroperoxide glutathione peroxidase. Its main function is to participate in the synthesis of enzymes in the body and protect the cell membrane. The structure and function are protected from excessive oxidation and interference, and have many important physiological functions. Through selenium supplementation in the body, it can resist viruses, anti-agin...
