| 摘 要： | 为了使得客土基盘造林技术在滨海泥质盐碱地造林绿化应用中有充分的理论依据，以河北唐山市南堡开发区盐渍化土壤为研究对象，通过野外试验，研究了客土基盘造林法对滨海盐渍土水盐运移规律的影响，并比较了不同客土配比方式的排盐、降盐效果。结果表明，对照组（未经改造的原状土）土壤含水量变化规律与降水量变化规律相同或稍有滞后，处理组（以不同客土配比方式制作的客土基盘A1、A2、A3、A4）同样受降水规律的影响，但各土层含水量变化幅度差异较大，且峰值的出现时间不同，不同客土配比方式对0~20 cm、40~60 cm土层含水量影响具有显著性差异，对20~40 cm、60~80 cm影响无显著性差异。对照组含盐量变化与含水量变化存在显著负相关关系，观测结束时，返盐程度剧烈；而处理组则无显著相关关系，总体含盐量保持持续降低。4种不同客土配比方式对各土层含盐量变化影响具有显著性差异，平均含盐量均有大幅下降，总体降盐效果：A1>A3>A2>A4，植物根区含盐量下降效果：A1>A2>A4>A3。综合分析，以A1处理方式，即原状土与基质土以1:2配比制作的客土基盘排盐降盐效果最好。

| Abstract: | In order to provide sufficient theoretical basis for the template with carrying soil for afforesting on coastal muddy saline land, the author took the saline soil of Nanpu economic development area in Tangshan, Hebei Province as the research object. A field experiment was conducted to research the effect of template with carrying soil for afforesting on the dynamic of water and salt of coastal saline soil and compared the effect of salinity reducing between different template with carrying soil. The results showed that the law of soil water content of control group （not transform undisturbed soil） were the same with rainfall or there was a slight lag. The treatment group （template with carrying soil are made in different ways which were numbered A1, A2, A3, A4） also had the effect of rainfall, but there was significant differences between water content of each layer and the peak appear on different time. There were significant differences between influence of each manufacture ways on water content of 0-20 cm, 40-60 cm soil layer, but 20-40 cm, 60-80 cm soil layer are opposite. There was very significant negative correlation between the changes of salt and moisture of control group, and salt content was severe increased at the end of observation; on the contrary, the treatment group had no significant correlation relationship, the change tendency of salt content remain lower overall. There were significant differences between each manufacture ways on salt content of each soil layer, the reduce degree of average salt content of each treatment group was larger than the corresponding control group. The overall effect of salt content reducing rank was A1A3A2A4; the effect of salt content reducing rank of root zone was A1A2A4A3. Comprehensive analysis, the effect of reducing salt content of template with carrying soil of A1 which was produced by primary state soil and substrate soil with 1：2 was better than the others. |
