摘　　要：采用盆栽试验研究了原污水、城市污水厂二级出水、氧化塘水及清水对水稻、玉米、白菜产量及品质的影响 ,同时测定了土壤重金属的累积状况。结果表明 :除清水对照 ,其余 3种不同污水均可使产量提高 ,但原污水浇灌使土壤重金属积累增加 ,品质变差。Effects of original sewage,water through two steps treatment from civic sewage treatment station,water from oxidation pond and no polluted water on yield and quality of rice,maize and Chinese cabbage were studied by using pot experiments.The accumulation of heavy metals in soil and grain also were tested.The results indicated that the three types of water except for no polluted water(as control)all could increase the yield.But the heavy metal accumulation were noticed with the experiment of original sewage,and the grain quality is much lower.
