| Abstract: |
| The contradiction between supply and demand of water resources in China is outstanding, especially the shortage of water for agricultural irrigation. Rational use of reclaimed water for farmland irrigation is one of the important ways to alleviate the shortage of agricultural water resources, and the influence of reclaimed water irrigation on water-soil-plant systems has aroused widespread concern. Irrigation with reclaimed water in agriculture is conducive to improving soil fertility. However, due to the limitation of treatment technology, a certain amount of heavy metals and organic pollutants may remain in reclaimed water, among which heavy metals are difficult to degrade, which may have a certain impact on soil, crops, groundwater and human health in irrigation areas. In view of the potential safety hazards and health risks of heavy metals in agricultural reclaimed water irrigation, the application status of agricultural reclaimed water irrigation at home and abroad was systematically summarized, and the effects of reclaimed water irrigation duration, water quality and different irrigation methods on the accumulation and migration risks of heavy metals in water-soil-plant system were analyzed and discussed, so as to provide more scientific theoretical guidance and safe and effective guarantee for agricultural reclaimed water irrigation in China. |
