摘　　要：适量的氟对人体健康有益,但是长期过量地摄入氟,则会带来不利影响。部分砖茶存在氟含量超标。因为磷矿石含有一定量的氟,生产的磷肥中存在水溶性氟和难溶性氟,磷肥中的水溶性氟对茶叶氟含量有较大影响。根据磷肥厂生产实际,考虑磷肥生产成本,通过控制磷肥中的氟含量能有效控制茶叶的氟含量,符合国家砖茶氟含量标准。提出茶树专用磷肥氟含量行业标准的建议。It is beneficial to human health with moderate fluoride,but the fluorosis may occur in extreme cases of prolonged fluoride over-consumption.The content of fluoride in some brick tea is usually very high in excess of the national standards.There are water soluble and water insoluble fluoride in phosphate fertilizer because the phosphate rock contains a certain amount of fluoride.The content of fluoride in phosphate fertilizer has an impact on the content of fluoride in tea.The production costs of the phosphate fertilizer were considered with a view to its fact of the phosphate fertilizer factory.The content of fluoride in tea can be controlled through the limitation on content of fluoride in phosphate fertilizer.The content of fluoride in tea will meet the national standards.The recommended standard on the fluoride content of phosphate fertilizer used in tea plantations are offered.
