调查分析了北京市125个有代表性的商品有机肥和传统有机肥样品的养分状况、重金属含量及部分微生物学指标.结果表明,目前北京地区有机肥品质并不理想.商品有机肥中,有73.7%的样品有机质含量低于标准,44.7%的样品养分含量不符合标准,73.7%的样品pH值、39.5%的样品含水量不符合标准.传统有机肥的有机质、全氮、全磷含量均高于商品有机肥,但含水量超过商品有机肥1.29倍.商品有机肥中重金属Cd、Cr、Pb、As、Hg的含量变异较大,平均分别为0.678、36.1、17.2、5.26、0.679 mg/kg.商品有机肥和传统有机肥中蛔虫卵死亡率均符合标准,传统有机肥中部分样品大肠杆菌值超标.

The study investigated the nutrition status,heavy metal content,and some microbiological indicators of 125 typical samples of commercial and traditional organic fertilizers in Beijing suburb.The results showed that the quality of those organic fertilizers was not so satisfied among commercial fertilizer samples,73.7% in organic matter,44.7% in total nutrition,73.7% in pH,39.5% in water content,respectively,did not meet the quality requirements of organic fertilizer standard.In traditional organic fertilizers,organic matter,total N,total P were higher than that in commercial fertilizer samples,but water content was 1.29 times higher too.Contents of heavy metals varied in the samples.Average values of Cd,Cr,Pb,As and Hg in commercial organic fertilizers were 0.68,36.05,17.18,5.26,0.68 mg/kg,respectively.Survival ascarid eggs met the standard in both commercial and traditional organic fertilizers,while coliform counts did not meet the standard in some traditional organic fertilizer samples.
