摘　　要：用不同浓度盐(NaCl)胁迫(CK、0.1%、0.3%、0.5%、0.7%、1.0%)处理盆土,以探究NaCl胁迫对土壤成分含量的影响。结果表明:随着盐胁迫处理浓度的升高,土壤氮(N)、有机质含量总体变化不明显;土壤磷(P)、有机磷、交换性钙含量总体呈下降趋势;土壤钾(K)、电导率呈上升趋势;土壤pH值、水解氮等则呈先降后升再降的趋势。In order to discuss the effects of NaCl stress on soil main ingredients contents, by watering the potted soil with treatments of different concentrations of NaCl solution （CK-0.0%, A-0.1%, B-0.3%, C-0.5%, D-0.7% and E-1.0%）, the author sampled and analyzed the soil. The results showed that： with the increasing of salinity, as a whole, the change of soil N contents and soil organic matter contents were not obviously, the change of soil P and soil organic P and exchangeable Ca contents were showed decreased, the change of soil K and conductivity were showed increased, and soil pH and hydrolysable N were showed different pattern with the increasing of salinity.
