磷石膏是生产复合肥磷酸-铵的副产品。我国东部沿海地区,磷酸一铵开发较早,有关农业部门对磷石膏的应用作了大量的试验研究和推广工作,取得了较好的社会经济效益。一、磷石膏的化学组成磷石膏富含钙和硫,其次为硅、磷、镁、铁,还有几种微量元素锰、钢、锌、铝等,这些成分均系农作物生长发育过程中所必需的营养元素。它们除了在植物生理代谢中发挥各自的功能外,又由于交互作用而增进了彼此的效应。

Phosphogypsum is a by-product of the compound phosphate-ammonium production. China’s eastern coastal areas, ammonium phosphate earlier development, the agricultural sector for the application of phosphogypsum made a lot of experimental research and promotion work, and achieved good social and economic benefits. First, the chemical composition of phosphogypsum Phosphogypsum is rich in calcium and sulfur, followed by silicon, phosphorus, magnesium, iron, there are several trace elements of manganese, steel, zinc, aluminum, these elements are the growth and development of crops Essential nutrients. In addition to their respective functions in the physiological metabolism of plants, they also enhance each other’s effects due to the interaction.
