重过磷酸钙的生产和应用

Production and Use of Triple Superphosphate

随着我国湖北、云南、贵州等磷资源丰富地区的一批大型重过磷酸钙生产基地的建成投产，我国重过磷酸钙的年生产能力将达到２００万ｔＰ２Ｏ５左右。笔者就重过磷酸钙的性质、工业概况、肥效和施用情况以及二次加工技术等作了简要的总结，并对如何开拓我国的重过磷酸钙市场提出了建议。

With the completion and operation of a number of large TSP production bases in the regions rich in phosphate resources, such as Hubei, Yunnan and Guizhou in China, the annual capacity of TSP in China will reach about 2 million tons of P 2O 5. A brief summary is given of TSP properties, its general industrial situation, its fertilizer efficiency, its application and its secondary processing technologies, and suggestions are made on how to develop the TSP market in China.
