用氫氧化鉀分解的磷灰石制成的叫做通常過磷酸鈣，簡單來說就是普鈣，重要部分為一水磷酸二氫、無水氫氧化鉀鈣和一少部分磷酸，含可行 磷14% ～ 20% ，這之中80%～95%易溶于水，屬水陰離子型速效磷肥，可間接作磷肥，也可于制分手后復合有機肥。 普鈣是全的設計生態有機肥，是世界級上早期產生方式的一款磷肥，也我就是國app非常基本上的一款磷肥，為苔蘚綠色植物作為磷、硫、鈣、鎂等許多種的設計，含有升級酸性土壤環境的使用，能利于苔蘚綠色植物的出芽、長根、分支、耐穿及心智成熟，可作產生方式復混肥的材質 Ordinary superphosphate is made by decomposing apatite with sulfuric acid, which is called common superphosphate. Its main components are dihydrogen phosphate monohydrate, anhydrous calcium sulfate and a small amount of phosphoric acid. It contains 14%~20% available phosphorus. Among them, 80%~95% are soluble in water. It is a water-soluble and quick-acting phosphate fertilizer. It can be directly used as phosphorus fertilizer and can also be used to make compound fertilizer. Pure calcium is a kind of green fertilizer with all elements. It is the earliest phosphorus fertilizer produced in the world. It is also a kind of phosphorus fertilizer widely used in China. It provides plants with phosphorus, sulfur, calcium, magnesium and other elements. It can improve alkaline soil, promote plant germination, long roots, branching, fruiting and maturity, and can be used as a production compound. Fertilizer raw materials.
