Abstract

Abstract: Micronutrients such as iron (Fe), zinc (Zn), and selenium (Se) are essential for human health. However, conventional fertilization approaches often suffer from low nutrient use efficiency, poor element mobility, and high environmental burden, making it difficult to effectively enhance the nutritional density of crop grains. The application of nanotechnology offers a novel solution for improving the uptake and targeted regulation of multiple micronutrients. Research on nano-iron, nano-zinc, and nano-selenium in major staple crops such as wheat, rice, and maize has rapidly advanced, demonstrating significant synergistic effects in promoting nutrient absorption, enhancing stress tolerance, and improving grain quality. The functional mechanisms and regulatory pathways of relevant nano-micronutrients in food crops were reviewed, and the key factors affecting their application effects were analyzed, including particle size, dose, application method and growth period. The existing problems such as unclear mechanism, insufficient safety assessment and limited application transformation were discussed, and the application prospects of nano micronutrients in green production and nutrition enhancement of food crops were prospected, in order to provide theoretical basis and technical support for the construction of an efficient, safe and sustainable crop nutrition intervention system.

Key words: nano-fertilizer, micronutrients, food crops, synergistic effect, nutritional enhancement
