采用等离子体原子发射光谱法（ＩＰＣ—ＡＥＳ）测定了我国云、贵、川、鄂、冀五省七个产地普通过磷酸钙（下称磷肥）中的稀土元素含量，并在冬小麦上施用云南开远、湖北孝感、河北阳原、河北藁城、贵州宏岩磷矿生产的磷肥，在亩施等量氮素和磷素（Ｐ２Ｏ５）的条件下，观察其中稀土元素对小麦的增产效应。结果表明，小麦施用稀土元素含量不同的磷肥，其产量随着磷肥中稀土元素含量的增加而提高 The contents of rare earth elements in common superphosphate (hereinafter referred to as phosphate fertilizer) in seven producing areas of Yunnan, Guizhou, Sichuan, Hubei and Hebei Provinces were determined by ICP-AES, and Yunnan The effects of rare earth elements on the yield of wheat were observed under the condition of equal amount of nitrogen and phosphorus (P2O5) under the condition of Km fertilizer, Kaiyuan, Xiaogan in Hubei, Yangyuan in Hebei, Yuncheng in Hebei and Hongyan phosphate in Guizhou. The results showed that the application of phosphate fertilizer with different contents of rare earth elements in wheat increased with the increase of rare earth element content in the phosphate fertilizer
