| 摘 要： | 设施氮、磷、钾肥（NPK）、施氮、磷、钾肥兼稻草还田（NPKS）、施氮、磷、钾肥兼2倍稻草还田（NPKS2）、施氮、磷、钾肥兼施紫云英（NPKG）和施氮、磷、钾肥兼施猪粪5个处理的长期定位试验，探讨了长期施用有机肥对土壤和糙米铜、锌、铁、锰和镉含量的影响。结果表明，土壤全铜、全锌和全镉因秸秆还田或施用紫云英、猪粪有明显提高，尤其是施用猪粪，土壤全铜、全锌和全镉较仅施用氮、磷、钾肥分别增长53.6%、23.6%、406.2%，达到极显著水平； 而全铁和全锰各处理间没有显著差异。长期施用有机肥增加了土壤有效态铜、锌和镉含量，其中施用猪粪土壤有效铜、锌和镉含量增加最为显著，分别比NPK处理增长了335.9%、320.8%、421.4%。长期施用猪粪明显地增加了糙米中镉含量，并超过国家卫生标准。长期施用畜禽粪便类的有机肥对农产品的安全应予以足够的关注。

| Abstract: | A long-term fertilization experiment,designed to have five application treatments of same rates of N,P,K,with or without incorporation of different organic fertilizers to the field,was carried out to determine the effects of these treatments on the concentrations of Cu,Zn,Fe,Mn,and Cd in soil and brown rice.Results showed that soil total Cu,Zn and Cd concentrations in the treatments with incorporation of rice straws(NPKS),2 folds rice straws(NPKS2),Chinese milk vetch(NPKG) and pig manure(NPKM) were higher t... |
