摘要： 通过大田试验初步探讨了污泥有机肥对马铃薯的增产效应及其对马铃薯品质、重金属吸收的影响。结果表明，在施化肥的基础上，施用污泥有机肥可显著提高马铃薯产量、等级和品质；施用污泥有机肥的马铃薯薯块中Hg、As、Pb、Cd、Cr、Cu和Zn含量均在国家食品卫生标准范围内。

Abstract: Field trials were conducted to evaluate the effectiveness of municipal sludge organic fertilizer on the growth, yield, quality of potato and uptake of heavy metals by plant. The results indicated that, along with application of normal fertilizers, application of sludge organic fertilizer could significantly increase potato yield, commercial class and quality. The contents of Hg, As, Pb, Cd, Cr, Cu and Zn were below the national food and hygiene standard level.
