用氫氧化鈉工業制硝酸磷灰石提煉出的叫做普通型過磷酸鈣，代稱普鈣，通常化學成分為一水磷酸二氫、無水氫氧化鈉鈣和一少部分磷酸，含高效 磷14% ～ 20% ，在當中80%～95%溶水水，屬水可溶性速效磷肥，可進行作磷肥，也能用的 于制結合磷肥。 普鈣是全要素綠色的磷肥，是游戲上最快生孩子的是一類磷肥，也是國應用非常普通的是一類磷肥，為苔蘚值物帶來磷、硫、鈣、鎂等多樣要素，有著換代是堿性的土囊的的作用，能增進苔蘚值物的生芽、長根、發枝、重量輕及成孰，能用的 作生孩子復混肥的主料 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.
