An experiment was carried out to study the content and enrichment characters of heavy metals chromium (Cr) and cadmium (Cd) in soil-plant system. The result indicated that fertilization could result in the accumulation of heavy metals in topsoil, and the Cd enrichment was more significant. Applying chemical fertilizer could increase the available Cd content in topsoil and increase the content of Cd in Chinese cabbage. Compared with the control, the Cd contents of Chinese cabbage under excessive fertilizer (N1), conventional fertilizer (N2), decrement fertilizer (N3) treatments were significantly higher than that in control (N0) treatment by 59.7%、41.1% and 40.3% respectively (P
