摘要
把污泥和垃圾配成有机复肥及培养土基质，对稻、生菜进行肥效试验及重金属含量检测。结果表明，若措施得当，污泥垃圾有较高的增产效果而重金属不致超标。并讨论了影响作物重金属含量的因素并就污泥垃圾作农用资源提出建议。
In this study , mud and garbage are used to make organic composite fertilizer and growth medium. Fertilization experiments with lettuce and rice are conducted and heavy metals in the crops tested. The results show that with proper measures, mud and garbage can raise yield obviously while the heavy metals remain under the criteria. Affecting factors of heavy metals in the crops are discussed and suggestions for agricultural utilization of mud and garbage proposed.
