摘 要: 通过薄露灌与传统灌溉对比试验研究,从田间排水水质、田间污染物排放负荷及田间污染物排放净负荷等方面论述了水稻薄露灌溉对稻田周围水体环境质量的影响。研究结果表明,薄露灌溉有利于降低氮、磷及有机物等污染物的田间排放浓度;对附近水体总磷、磷酸盐及COD的污染程度要比传统灌溉小。Through comparison experimental study on the thin and wet irrigation and traditional irrigation, the impacts of rice thin and wet irrigation on the surrounding water environment qualities are expatiated from the aspects of field drainage water quality, field contaminants discharge load and field contaminants discharge net load. The results show that thin and wet irrigation is propitious to reduction of the concentration of the field contaminants discharge, and the contamination extents of total phosphorus, phosphate and COD of the surrounding water bodies of the thin and wet irrigation are smaller than those of traditional irrigation.
