| 英文摘要 | The phytotoxicity of salts in composted sewage sludge (CSS) was evaluated. Concentrations of sodium (Na(+)), chloride (Cl(-1)), calcium (Ca(2+)), and magnesium (Mg(2+)) were present at levels that would induce salt stress in plants. Nutrient imbalances were also found that would adversely affect the use of CSS as a growth medium. To further understand the phytotoxic nature of these salts, sodium chloride (NaCl), calcium nitrate [Ca(NO(3))(2)] and magnesium nitrate [Mg(NO(3))(2)] solutions were used to simulate the composition of salts found in CSS in an investigation of radish (Raphanus sativus L.) seed germination. High concentrations of Ca(2+) (92.1 mmol.L(-1)) and Mg(2+) (27.4 mmol.L(-1)) inhibited seed germination to an equal extent as did Na(+) (40.6 mmol.L(-1)). The lower concentration of Ca(2+) (10 mmol.L(-1)), however, significantly relieved the stress caused by NaCl. These results indicated that the composition and total amount of Na(+), Cl(-1), Ca(2+), and Mg(2+) in CSS should be carefully monitored before it is used as a soil amendment or growth medium. |
