[en] Pot experiments were conducted in the laboratory with lime applications to decrease trace elements in Chinese cabbage produced on soils contaminated by trace ele- ments in the intensive periurban area in Chenggong County, Yunnan Province, China. Soil was an acidic loam developed from lacustrine-alluvial deposits. Results showed the following: (1) soil pH increased from 5.3 to 6.5, and acetic-acid-extractable trace-element contents and ratio of acetic-acid-extractable trace-element contents in treatments relative to those in the control (RRCT) decreased with increased rate of lime application. (2) Chinese cabbage more easily absorbed acetic-acid-extractable trace elements. Enrichment coefficients related to trace-element availability (AEC) of lead (Pb; mean: 3.3) and zinc (Zn; mean: 5.8) were stable, and the AEC of cadmium (Cd) was 1.8–2.0 with increased lime application rate. (3) Trace-element contents in Chinese cabbage decreased, and biomass of Chinese cabbage increased, with lime application rate. Trace-element contents in soil solution and acetic-acid-extractable trace-element contents can predict trace-element contents in Chinese cabbage, especially for soil solution. Lime quality and trace-element accumulation in Chinese cabbage should be taken into account when amendment is added to in situ soil contaminated with trace elements.
