在野外考察、GPS定点和土壤采样分析的基础上,借助Statistics、Excel等软件对盐离子含量、电导率与离子含量的关系、土壤总碱度与离子含量的关系、土壤水溶液中总溶解固体(TDS)与离子之间的关系、土壤含盐量与电导率的关系、盐离子间相关性以及土壤含盐量与农业产量的关系作了探讨。得出:该绿洲土壤pH值的平均值为7.86,属于碱性土壤。土壤含盐量较高,0～10 cm土层中的含盐量最大,平均值达到4.68%。土壤阳离子主要以Na+、K+、Ca2+和Mg2+为主,各阴离子在土体中的含量为Cl->SO42->HCO3-,而CO32-离子在实验中未检测到。Na+与Cl-呈正相关,K+与HCO3-呈正相关,Ca2+与SO42-呈正相关。从而进一步说明,该绿洲盐渍化土壤为氯化物盐化土。
On the basis of field investigation, GPS fixed point and soil sampling and analysis, the relationship between salt ion content, conductivity and ion content, total alkalinity and ion content of soil, total dissolved solids TDS) and ions, the relationship between soil salinity and conductivity, the correlation between salt ions and the relationship between soil salt content and agricultural yield were discussed. The result shows that the average soil pH of the oasis is 7.86, belonging to alkaline soil. Soil salt content is higher, the salt content in 0 ~ 10 cm soil layer is the largest, with an average value of 4.68%. The main cation of soil is Na +, K +, Ca2 + and Mg2 +, and the content of each anion in the soil is Cl-> SO42-> HCO3-. CO32- ions are not detected in the experiment. There was a positive correlation between Na + and Cl-, K + was positively correlated with HCO3-, and Ca2 + was positively correlated with SO42-. To further explain that the oasis salinization of soil chloride chloride soil.
