摘　　要：文章对浙江省各地抽取的复合肥料中水溶性氟含量进行调查研究,归纳总结其含量和区域分布情况,分析其含量与复合肥料总养分、氮、磷、钾含量的相关性。结果表明,复合肥料中水溶性氟含量差异很大,分布区间为0.01%~3.50%,平均值为0.43%;从区域分布上看,嘉兴、湖州两地的氟含量均值很高,分别达到了1.07%和0.89%;从养分浓度分布上看,总养分含量≥45.0%的高浓度复合肥料占比最高,达到78%,其水溶性氟含量的平均值也是最高的,达到0.47%,氮和磷均是标明量为15%的复合肥料中水溶性氟含量平均值最高,达到0.62%和0.59%,钾则是标明量大于20%的复合肥料中水溶性氟含量平均值最高,达到0.63%。In this paper,the water-soluble fluorine content in composite fertilizers sampled from Zhejiang Province was investigated and summarized.The correlation between its content and total nutrient,nitrogen,phosphorus and potassium content of compound fertilizer was analyzed.The results showed that the content of water-soluble fluorine in composite fertilizers varied greatly,ranging from 0.01%to 3.50%with an average of 0.43%,while the average content of fluorine in Jiaxing and Huzhou was very high,1.07%and 0.89%respectively.In terms of nutrient concentration distribution,the highest proportion of high-concentration composite fertilizers with total nutrient content≥45.0%was 78%,and the average content of water-soluble fluorine was also the highest,reaching 0.47%,the average content of water-soluble fluorine was the highest in the 15%nitrogen composite fertilizer and phosphorus,reaching 0.62%and 0.59%respectively.The average content of water-soluble fluorine was the highest in the composite fertilizer of more than 20%potassium,0.63%.
