摘要
铜是农作物生长发育所必须的营养元素。当土壤中铜含量超过一定浓度时,将对作物生长发育及产量产生影响。该文探讨了各类土壤中铜污染对水稻产量的影响,并就农田中铜污染浓度与水稻减产的临界值作了阐述。
Copper is a nutrient element for crops growth. It will have effect on the growth and yield of crops when the copper content in soil is over a critical concentration. The paper discusses the effect of Cu pollution in various soils on the yield of rice. The viewpoint about the critical value of Cu pollution in farmland and decreasing rice yield is described.
