摘　　要：以龙口市和高密市污水处理厂的再生水为灌溉水源,进行玉米再生水灌溉试验,研究了不同灌水定额对玉米产量、品质、含重金属量的影响。研究表明,再生水灌溉条件下,玉米品质及产量有不同程度的提高,籽粒含重金属量与清水灌溉并无差异,重金属在植株体内的累积表现为:根>茎>籽粒,籽粒含重金属量符合《粮食卫生标准》(GB2715—2005)和《食品中污染物限量》(GB2762—2005)的要求。The project, which used the reclaimed water from Longkou and Gaomi sewage treatment plant as irrigation water, was conductded by four different irrigation schemes. The influences of different irrigation schemes on yield, quality, and heavy metal content were studied. The research results showed that the quality and yield of corn increased in different degrees. The heavy metal content of grain was no difference between reclaimed water and fresh water. The heavy metal accumulation in corn was root〉 stem〉grain, and the content of heavy metal did not exceed requirement of Grain Health Standard（GB2715-2005） and Maxium Limited Standards for Contaminants in Food（GB2762-2005）.
