In this study, the concentrations of total Cd and available Cd in different cultivation greenhouses were investigated to illuminate the effect of greenhouse on Cd accumulation and its activation under greenhouse vegetable production (GVP). The results revealed that higher Cd contents (including total Cd and available Cd) accumulated in GVP surface layer (0-20 cm), and increased with duration years. Total Cd contents and Cd activation rate were positively correlated with GVP duration (P<0.05). Cd accumulation and activation in soils were mainly ascribed to anthropogenic input, such as heavy inorganic or organic fertilizer application. For greenhouse sustainability, much more attention should be paid to Cd contents in soils of 13-yr greenhouses.
