NaCl胁迫对土壤成分含量的影响

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。

Effects of NaCl Stress on Soil Main Ingredients Contents

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.
