摘要： A pot experiment, in which composted pig manure was applied to soils at rates of 0%, 0.5%, 1.5%, 3.0%, and 5.0% (W/W) to simulate additions of different amounts of cadmium (Cd), copper (Cu), and zinc (Zn) to soil, was conducted to assess accumulation of metals by rice (Oryza sativa L.) plants from soils treated with manure. Results indicated that Cd concentrations in rice grains were more than the limit of 0.2mg kg(-1) when 0.14 mg kg(-1) or more Cd was loaded to Ferralsols by manure application, but it was not more than the limit in Calcaric Cambisols. Zinc contents in polished rice grains did not exceed the permissible limit of 50 mg kg(-1) in two soils. Copper concentrations in rice grain were slightly more than the limit of 10 mg kg(-1) in Ferralsols but not in Calcaric Cambisols. Results suggested greater risk of heavy-metal contamination from manure to paddy rice in Ferralsols than in Calcaric Cambisols.
