| 摘 要： | 本文通过盆栽试验研究土壤中镉铜复合污染对水稻生长效应的影响,并探讨了有效态铜、镉的提取剂。结果表明,2.5％醋酸可作为酸性水稻土有效态铜、镉的提取剂,土壤含镉5mg/kg对铜的水稻产量效应未有影响,但糙米含镉量超标。

| Abstract: | Effect of heavy metal mixture pollution on rice growth is studied through pot experiment. Solutions for extracting available copper and cadmium are also explored. The results indicate that 2. 5% HAc can be used as available copper and cadmium extracting agent in acid paddy soil. Less than 5 mg/kg cadmium in soil will not have any effect on rice yield, however, cadmium concentration in the rice will exceed China National Adminissible Standard foi Food. |
