In order to remove Cd by plants cultivation in the cadimum contaminated soil, six fibers, four flowering and two sapling plants were cultivated at Cd treated soil, adjusted to 15 ppm. The Cd contents of plants and absorbed Cd concentration in plant, and residual Cd in soil were analyzed. The Cd content in marigold was the highest, 161.7 ppm, 22.5 times higher than rice. The Cd contents in plants was in the order of 58.3 ppm in sedge, 58.0 ppm in coreopsis, 43.5 ppm in sunflower, 38.3 ppm in scruber, and 31.9 ppm in flax. The absorbed Cd in Popuaus alba x P. glandulosa was the highest, 24.11mg/pot, 35.5 times higher than rice. The absorbed Cd by plants were in the order of 10.86mg/pot in Italian poplar, 9.61mg/pot in marigold, and 9.04mg/pot in kenaf. The residual Cd contents was the lowest in Popuaus alba x P. glandulosa soil and cotton followed. Absorbed Cd dontent in plants was negatively correlated with the residual Cd nocentration in soil.
