Abstract:

A pot experiment was conducted to study the influence of S, (NH4)2SO4, CaSO4, and K2SO4 on soil Pb and Cd uptake by oilseed rape (Brassica napus L. cv. Wuyueman) and railway beggarticks herb (Bidens pilosa.L) in lead and cadmium combined contaminated soil. The results showed that the S and (NH4)2SO4 significantly increased the total lead and cadmium uptake in the shoot of Brassica napus, respectively. (NH4)2SO4 and CaSO4 significantly decreased the total lead uptake in the shoot of Bidens pilosa. Elemental sulphur and (NH4)2SO4 are the effective agricultural practices to enhance uptake of lead and cadmium by Brassica napus in lead and cadmium combined contaminated soil, respectively.

Key words: sulphur fertilizer, oilseed rape, railway beggarticks herb, lead, cadm
