2. The chemistry behavior research of wollastonite indicated that the silicon-potassium fertilizer has a chemical active in organic acid. The factors affecting manurial effect of silicon-potassium fertilizer are not only soil pH and desilicification, but also content and type of organ in the soil. Wollastonite chemistry behavior indicates that silicic acid can be dissolved out from silicon-potassium fertilizer in chlorhydric acid solution if pH of solution is not smaller than 2. The drop of apparent density, increase of DBP sorptive rate and specific surface for leavings indicate that hydrated silicon oxide is polyporous, and those mineralogic feature presignify that silicon-potassium fertilizer has a role of conservation of both Moisture and Fertility and improving soil structure. After active ingredient releasing, silicon-potassium fertilizer leaves half the substance (non-active ingredient)in soil.
熟料单矿物在酸溶液中的化学行为研究表明,硅钾肥矿物在有机弱酸中的化学活性较好,影响硅钾肥肥效发挥的因素是土壤pH值和土壤的去硅化程度,还有土壤有机质的含量与种类;硅灰石在盐酸溶液中化学行为表明,在反应体系pH不小于2的情况下,硅钾肥矿物大量溶出硅酸根组分;溶解残余物表观密度降低、DBP吸着率和比表面积增加表明水合二氧化硅是以多孔形式存在,为硅钾肥具有保水保肥、改良土壤结构的提供了矿物学依据。
