Abstract:

This paper summarized the existing preparation technologies of nano-selenium, and compared the advantages and disadvantages of different preparation technologies. The research of nano-selenium’s role in improving crop growth, product quality and crop resistance to diseases and pests, and extending shelf life was reviewed. At the same time, the alleviation effects of nano-selenium on crop physiology and biochemistry, plant primary and secondary metabolite synthesis, and agricultural product quality under heavy metal stress were explored. While increasing the selenium content of crops, nano-selenium can continuously improve the quality and efficiency of agricultural industry, which is reflected in regulating the content of trace elements in crops, enhancing plant health, preventing and controlling pests and diseases, reducing the risk of crop yield reduction and fruit quality deterioration, and inhibiting the accumulation of heavy metals. Summarizing previous scientific research achievements is conducive to understanding the benefits of nano-selenium, which is easy to be absorbed by animals and plants, to agriculture and other fields, providing technical ideas for the development of healthy and green agriculture and functional agricultural products, and impelling the modern industrial system construction with scientific and technological strength.

Key words: nano-selenium, preparation method, exogenous selenium fertilizer, inhibition of heavy metals, crops
