邢台市咸水分布特征与合理开发利用研究

根据对邢台市咸水成因及咸水分布特性分析,结合邢台市咸水水化学特征,指出咸水的水质类型与其矿化度关系密切。分析邢台市对咸水利用的试验研究成果,并对咸水灌溉条件进行探讨,确定不同农作物的耐盐极限值。结果表明,咸水的矿化度小于或等于3g/L,对作物和土壤不会产生危害。在此基础上探讨邢台市咸水利用的措施和方法,建议因地制宜,选用咸水间接利用方式,减少盐分对作物及土壤的危害。

Characteristics of saltwater distribution in Xingtai City and its reasonable development and utilization

Based on the analysis of the cause of formation of saltwater in Xingtai City and its distribution and hydrochemical characteristics, it is pointed out that the saltwater quality is of close relationship with the degree of mineralization. By analysis of the experimental results of saltwater utilization in Xiangtai City and discussion on conditions suitable for saltwater irrigation, the ultimate values of salt resistance of different crops are determined. Research shows that, when the degree of mineralization is smaller than 3g/L, the saltwater will do no harm to crops and soil. Finally, some measures for saltwater utilization are discussed, and it is suggested that the utilization of the saltwater should accord with the practical situation, and that the indirect utilization mode should be taken to diminish the saltwater-induced harm to crops and soil.
