摘　　要：近15年来,我国低浓度磷肥(过磷酸钙和钙镁磷肥)产量一直保持低速增长,已达468万t P2O5,几乎占磷肥产量的50%。由于其单位P2O5价格只相当于高浓度磷肥的80%左右,而且含有硫、钙、镁、硅等中量营养元素,又充分利用了中低品位磷矿资源,减少了硫酸的消耗,是一种资源节约型产品。实践证明,它将与高浓度磷肥长期共存。要转变传统观念,用科学发展观重新认识其价值,给予大力重视和支持,以实现可持续发展,建设节约型社会。With annual 4.68 million ton P2O5 and a half of total output of phosphate fertilizers in China, the 2 low analysis phosphate fertilizers（SSP and FCMP）have been increasing in a low growth rate for 15 years. The advantages reflect its resource -effective properties, such as only possessing 80% unit P2O5 price of high -analysis phosphate fertilizer, containing the secondary nutrient elements sulfur, calcium, magnesium and silicon etc., making full use of medium and low grade phosphate rock and decreasing the consumption of sulfuric acid. The value of low -analysis phosphate fertilizer should be re -estimated, and paid great attention and support according to the view-point of scientific development. The conventional view should also be changed to these, that the co existence between the low -analysis phosphate fertilizer and the high-analysis one will be a long-term course, aimed at establishing a sustainable development, resource - effective society.
