一种硅钙镁钾矿质多元素复合肥及其制备方法
摘要：
本发明公开了一种硅钙镁钾矿质多元素复合肥及其制备方法，该矿质多元素复合肥是一种基于富钾岩石制备的不溶于水的拘溶性肥料，含有大量元素钾，中量元素硅、钙、镁和多种微量元素，其中，氧化钾的质量分数≥8%，二氧化硅、氧化钙、氧化镁之和的质量分数≥50%，水的质量分数≤3%，同时兼顾微量元素。硅钙镁钾矿质多元素复合肥是一种不溶于水的拘溶性肥料，具有不蒸发、不下渗、不流失的特点，使用后不会造成土壤的酸化、碱化、板结；可作为基肥或追肥使用，使用后对改善土壤结构、增加土壤有效营养成分大有好处。
摘要（英）：

The invention discloses silico-calcium magnesium-potassium mineral multielement compound fertilizer and a preparation method thereof. The mineral multielement compound fertilizer is a water-insoluble dissolving resisting fertilizer prepared based on potassium-rich rock and comprises microelement potassium, secondary element silicon, calcium, magnesium and multiple trace elements, wherein the mass fraction of potassium oxide is larger than or equal to 8%; the total mass fraction of the silica, the calcium oxide and the magnesium oxide is larger than or equal to 5%; the mass fraction of water is less than or equal to 3%; and simultaneously the trace elements are considered. The silico-calcium magnesium-potassium mineral multielement compound fertilizer is the water-insoluble dissolving resisting fertilizer and is characterized by non-infiltration, non-infiltration and non-loss, can not cause the acidification, alkalization and hardening of the soil after being used, can be used as the base fertilizer or top application, and is of great benefit to improving the soil structure and increasing the efficient nutrition components.
