| Abstract: |
| In this study, a pot experiment was conducted to investigate the effects of three kinds of sulfur fertilizer (sulfur, calcium sulfate, ammonium sulfate) on growth and Cd and S accumulation in Amaranshus mangostanus L. in two acidic soils (yellow-brown soil and lateritic red soil). The purpose was to select a suitable sulfur fertilizer to assist Amaranshus mangostanus L. in remedying Cd-contaminated soil. The results showed that the application of S fertilizers on the two acidic soils enhanced Cd tolerance by promoting S assimilation in Amaranshus mangostanus L. and improved plant growth significantly. In addition, the Cd contents in the shoots and roots of Amaranshus mangostanus L. increased when S fertilizers were supplied to the yellow-brown and lateritic red soils, respectively. The accumulation of S and Cd increased with application of the different S fertilizers to the two acidic soils. For the yellow-brown soil and lateritic red soil, ammonium sulfate treatment led to the greatest increase in cadmium accumulation in the shoot, i.e., 1.45 and 2.39 times higher than that of CK, respectively, whereas the sulfur treatment led to the lowest. Ammonium sulfate as the nitrogen-containing sulfur fertilizer, applied on the yellow-brown and red soils, can effectively assist Amaranshus mangostanus L. to remedy Cd-contaminated soil. |
