1.
The result s showed that,the islets soil and red earth of Zhejiang were distinct, the main clay minerals were illies,higher base saturation and pH,the main base ion were Ca+{2+} and Mg+{2+},higher ba value, Bt value 0.
浙江省海岛尽管处在亚热带红壤基带内 ,但由于海洋环境对海岛的独特影响 ,使海岛土壤成土作用出现与同纬度的大陆红壤有明显的差异性 :即表现出具有盐基饱和度高、pH值较高、盐基离子以钙、镁离子为优势的组合、粘粒矿物以伊利石为主、风化淋溶系数较大等特征 。
2.
Latosol was treated with various soil amendments,and one year after the field trial it was determined in terms of soil cation exchange capacity,effective cation exchange capacity,soil exchangeable base-cation concentrations and base saturation to observe the effect of different soil amendments application on the latosol exchangeable property.
对砖红壤施用不同的改良剂,进行1a的大田试验后,测定土壤的阳离子交换量、有效阳离子交换量、盐基离子总量以及盐基饱和度来研究不同土壤改良剂对酸性土壤交换性能的影响。
4) saturation

Method for Rational Determination of Mud Density and Undersaturation during the Drilling in Salt Formation;
盐层钻井过程中合理钻井液密度及含盐饱和度的确定
5) base desaturation

碳酸盐饱和度
补充资料:盐基饱和度
分子式:
CAS号:
性质:土壤吸附交换性盐基总量的程度。以土壤交换性盐基总量占土壤阳离子代换量的百分比表示。当土壤胶体所吸附的阴离子基本上属于盐基离子时,称为盐基饱和土壤,呈中性或碱性、强碱性反应;反之,当非盐基离子占相当大比例时,称为盐基不饱和土壤,呈酸性或强酸性反应。盐基饱和度的大小,可用作施用石灰或磷灰石改良土壤的依据。
