通过滨海地区原生盐碱土的淋洗试验,分析了滨海地区盐碱土的水盐运移规律,发现淋洗过程中淋滤液呈脱盐碱化趋势,淋洗后土壤中离子组成由原来的Cl-、Na+和Ca2+为主转变为以HCO3-、Ca2+和Na+为主,淋洗后土壤各项指标均符合植物生长要求。
The indoor soil column simulated experiments were adopted to study the law of saline soil's water and salt movement in this paper.Leachate showed a desalting alkalization tendency during washing,and the dominant ionic of soil changed from Cl-,Na+ and Ca2+ to HCO-3,Ca2+ and Na+ after washed.Those indexes of soil met the requirement of plant growth after washed.
