Research Progress of Engineered Nanomaterials in Plant Resistance Enhancement and Soil Improvement

Abstract

Abstract:

This review systematically summarizes the mechanisms and application prospects of engineered nanomaterials (ENMs) in enhancing plant stress tolerance and improving soil quality. Through literature review and case studies, we focus on the physiological and molecular mechanisms by which different types of ENMs enhance plant salinity tolerance, drought resistance, and resistance to biotic stress. We also analyze the regulatory effects of ENMs on soil structure, nutrient availability, microbial communities, and pollutant remediation. Research indicates that ENMs can enhance plant stress resistance by modulating the antioxidant system, ion homeostasis, and gene expression, while also promoting soil health through improvements in soil physicochemical properties and microbial function. However, it is noted that the transport, transformation, and potential ecological risks of ENMs in the soil-plant system require further evaluation. Ultimately, promoting the sustainable application of ENMs in agriculture must balance their efficacy with environmental safety.

Key words: engineered nanomaterials, plants, nano fertilizer, sustainable agriculture, stress resistance, soil improvement, ecological security
