【 摘 要 】

In this study, we determined the influence of cultivation age on Cu accumulation in greenhouse soils. The concentration of plant available Cu (A-Cu) decreased with depth, and the contents of top soils (0-40 cm) in greenhouses were higher than those of the open field. There was a positive correlation between A-Cu concentrations in soils and cultivation ages (R2=0.572). The contents of total Cu (T-Cu) decreased with depth, and positively correlated with cultivation ages in top soils (0-20cm) (R2=0.446). The long-term usage of manures can cause Cu increase and accumulation in greenhouse soils in comparison to the open field.
