摘要
本文通过室内模拟实验 ,并结合野外灌水脱盐实验 ,对比分析了土壤和淋溶液中的电导率、盐基离子以及pH的动态变化 ,探讨了滨海盐渍土灌水脱盐的动态规律与机理 ,为节约用水和盐渍土改良利用提供了理论依据。
By indoor and field simulated experiments, the dynamic of soil electric conductivity, saline hydronium and pH value was analyzed in seashore salinized soil and its leaching liquid, and its dynamics and mechanism of salt leaching from watering were discussed, which can provide theoretical basis for water resource saving and salinized soil meliorating.
