In recent years, with the increasing scarcity of water resources, reclaimed water irrigation has been widely applied in agricultural production as an important measure to alleviate water shortages. However, due to the complex composition of reclaimed water, long-term irrigation may lead to soil physical structure degradation, salt accumulation, nutrient imbalance, and alterations in microbial community composition, thereby posing potential risks to crop growth, quality, and food safety. Based on relevant literature and typical cases from both domestic and international studies, this paper systematically evaluates the mechanisms by which reclaimed water irrigation affects soil structural stability, chemical properties (including salt and nutrient dynamics), and microbial ecosystems, while also examining its impacts on crop physiological growth, quality changes, and heavy metal accumulation risks. Furthermore, it discusses in detail the key technologies, data collection, and analytical methods used in long-term monitoring of soil and crops. This paper aims to provide a theoretical basis and technical support for developing scientific and rational reclaimed water irrigation management strategies, ensuring the safety and sustainability of agricultural production.
