根据246个盐渍土剖面的调查分析资料,对本省滨海盐渍土的盐分消长规律进行探讨。结果表明:各类盐渍土的含盐量变幅较大,多数为0.2~2.0%,并随土壤物理性粘粒的增加而提高.物理性粘粒每增加10%,土壤含盐量提高0.25%,且与地下水,海水的矿化度呈极显著正相关。同时,不同生态条件、不同土壤类型、不同围垦年限和耕作利用方式,对土壤盐分的含量与分布及土壤剖面盐分的组成的影响也有差异。 Based on the investigation and analysis of 246 saline soil profiles, the salinity declines of coastal saline soils in this province were discussed. The results showed that the salt content of all kinds of saline soils varied greatly from 0.2% to 2.0%, and increased with the increase of physical clay, and the salt content of soil increased by 0.25% %, And has a very significant and positive correlation with the salinity of groundwater and seawater. At the same time, the effects of different ecological conditions, different soil types, different reclamation years and tillage and utilization methods have different effects on the content and distribution of soil salinity and the composition of salt in the soil profile.
