摘要： This study investigated the micro area of cell tissue through synchrotron radiation X-ray fluorescence and high-performance liquid chromatography-atomic fluorescence spectrometry to indicate the effect of exogenous phosphorus (P) on the distribution of arsenic ( As) absorption and the formation of As content in Panax notoginseng. Results showed that distributions of relative contents of As and P are the same in roots of P. notoginseng. Treatment with As50mg/l+P100mg/l resulted in the decrease of As content in P. notoginseng. From stems and leaves of arsenic fluorescence distribution can be seen that arsenic into P. notoginseng plant and part of the trend of the transport to the ground, therefore rise to arsenic in the blade also is relatively small, mainly concentrated in the stem. Exogenous P treatment can effectively reduce the root's absorption and accumulation of As, thereby reducing the harmful effect of As on P. notoginseng.
