一种多元素复合磷肥及其制备方法
摘要：
本发明公开了一种多元素复合磷肥及其制备方法，所述多元素复合磷肥包括下述重量份组成的原料：300～400份的磷酸，160～200份的液氨，100～150份的硫酸钾，80～160份的硫酸，8～10份的氧化镁，3～5份的营养包；所述营养包为包含元素锌、硼、锰的粉末或氧化锌粉末。相比传统的磷肥产品，例如磷酸二铵，本发明提供的复合磷肥，营养元素更加齐全，不仅含有作物生长所需的大量营养元素氮、磷、钾，还含有中量元素硫、镁和多种微量元素硼、铁、锰、锌等，养分齐全，功效全面，增产、增质、增效明显。
摘要（英）：

The invention discloses a multi-element composite phosphate fertilizer and a preparation method thereof. The multi-element composite phosphate fertilizer is prepared from the following raw materials in parts by weight: 300 to 400 parts of phosphoric acid, 160 to 200 parts of liquid ammonia, 100 to 150 parts of potassium sulfate, 80 to 160 parts of sulfuric acid, 8 to 10 parts of magnesium oxide and 3 to 5 parts of a nutrient pack. The nutrient pack is powder containing elements of zinc, boron and manganese or zinc oxide powder. Compared with traditional phosphate fertilizer products such as diammonium phosphate, the composite phosphate fertilizer provided by the invention is more complete in nutrient elements, not only contains a large amount of nutrient elements such as nitrogen, phosphorus and potassium required by crop growth, but also contains secondary elements such as sulfur and magnesium and various trace elements such as boron, iron, manganese and zinc, and is complete in nutrient, comprehensive in effect and obvious in yield increase, quality improvement and synergy.
