过磷酸钙是我国重要的磷肥品种,然而近年来过磷酸钙生产销售呈萎缩趋势,剖析过磷酸钙生产销售下降的原因。通过研究和分析国内外文献资料,总结前人在过磷酸钙加工工艺改进、产品物料组分设计以及施肥方式优化等方面的研究工作,以期为过磷酸钙增效产品研发提供科学参考。最后分析过磷酸钙在水培条件下的EC值和p H值变化特点,并对该类肥料的发展趋势进行了展望。
Superphosphate is an important phosphate fertilizer species in our country. However, in recent years, the production and sales of superphosphate have been shrinking, and the reasons for the decline in sales of superphosphate have been analyzed. Through the research and analysis of domestic and foreign literature, summarizes the predecessors in the improvement of calcium superphosphate processing technology, product material composition design and optimization of fertilization methods and other aspects of research, in order to provide scientific reference for the research and development of synergistic products of superphosphate. Finally, the EC and p H values of superphosphate in hydroponics were analyzed. The development trend of this type of fertilizer was also prospected.
