采用真空置换法（ｖａｃｕｍｎｄｉｓｐｌａｃｅｍｅｎｔ）提取土壤溶液，研究了土壤温度及储存时间两种处理对离子化学形态电脑模型计算结果的影响．研究不同处理效应的电脑输出数据以负对数表示，计有：（１）Ｈ＋、Ｃａ２＋、Ａｌ３＋及ＳＯ的离子活度，（２）（Ａｌ＋）（ＯＨ）３、（Ａｌ３）２（ＯＨ）６（Ｈ４ＳｉＯ４）２及Ａｌ３＋）３．７７（Ｈ４ＳｉＯ４）３．２４（Ｋ＋）０．２４（Ｃａ）０．０８（Ｆｅ＋）０．２４（Ｍｇ）０．２０（ＯＨ）１２．８３的离子活度积和（３）Ｃａ２＋／Ａ１３＋的离子活度比．结果表明，储存期长短的影响比不同干湿处理为显著，两处理的交互影响很少见．根据ＰＨ—１／３ｐＡｌ对ＰＨ４ＳｉＯ４的图发现，无定形ＳｉＯ２、高岭土、绿泥化蛭石（ｈｙｄｒｏｘｙｉｎｔｅｒｉａｙｅｒｅｄｖｅｒｍｉｃｕｌｉｔｅ）及潜晶水铝矿（ｃｒｙｐｔｏｃｒｙｓｔａｌｌｉｎｅｇｉｂｂｓｉｔｅ）的稳定性几乎不受样品处理的影响，但是ＰＨ４ＳｉＯ４在土样风干后再湿润组中增加显著．当采用电脑模型分析土壤溶液组分中离子的化学形态时，土壤预处理的方法需要作较为详细的说明．
The soil solution was extracted by vacumndisplacement, and the effects of soil temperature and storage time on the calculation results of ion chemical morphological model were studied. The computer output data to study the effects of different treatments are expressed as negative logarithms and include: (1) ion activities of H +, Ca2 +, Al3 + and SO, (Al +) (OH) 3, (Al3) 2 6 (H4SiO4) 2 and Al3 +) 3.77 (H4SiO4) 3.24 (K +) 0.24 (Ca) 0.08 (Fe +) 0.24 (Mg) 0.20 (OH) 12.83 Degree product and (3) Ion activity ratio of Ca2 + / A13 +. The results showed that the effect of storage duration was more significant than that of different wet and dry treatments, and the interactions between the two treatments were rare. According to the plot of PH-1 / 3pAl vs. PH4SiO4, the stability of amorphous SiO2, kaolin, hydroxyinteria layered vermiculite and cryptocrystalline gibbsite was almost unaffected by the sample treatment, but the stability of PH4SiO4 on soil Such as air-dry group increased significantly. When using computer models to analyze the chemical form of ions in soil solution components, soil pretreatment methods need to be described in more detail.
