【摘要】 本文对福鼎和槠叶齐夏秋绿茶的锰含量及锰的浸出率进行研究,结果表明夏秋绿茶锰含量范围1876.8～2334.7mg·kg-1,福鼎和槠叶齐锰含量变化趋势基本一致,以8月底锰含量最高,7月初和9月中旬较低;两品种锰浸出率范围35.3%～42.7%,以槠叶齐较高,福鼎较低,两品种浸出率随时间的变化趋势为:槠叶齐随时间的推移而锰浸出率降低,福鼎随时间的推移锰浸出率升高。更多还原

【Abstract】 Study on Mn content in summer and autumn green tea and Rate of Mn Extracting,the result show that the Mn content in summer and autumn green tea is in 1876.8～2334.7 mg·kg-1 range,Mn content is similar in FUDing and ZHUYeQi varieties,Mn content is highest in late Augest,while is lower in early July and Sptember;The range of Mn extracting rate in FUDing and ZHUYeQi varieties is 35.3%～42.7 %,Mn extracting rate is higher in ZHUYeQi .With time goes on,The Change of Mn extracting rate is that:Mn extracting rate in decrease ,but that of FUDing increase.更多还原
