利用３２Ｐ示踪技术及常规生物化学分析方法，动态地测定了人参对叶面磷的吸收、分配及代谢过程。结果表明，五年生人参青果期叶面供磷，随供磷后时间的推移，吸收率呈递增趋势。供试３６ｄ平均吸收率为２１．９７％，而且以正在发育的果实和根部为主要分配中心。叶面吸收的３２Ｐ迅速参与代谢过程，由无机态合成多种有机磷化物，其中８０％左右掺入酸溶性组分 32P tracer technology and conventional biochemical analysis methods were used to determine the absorption, distribution and metabolism of ginseng phosphorus. The results showed that the phosphorus uptake rate of five-year-old ginseng fruits in green stage increased with the passage of time. The average absorption rate of 36 d was 21.97%, and the developing fruit and root were the main distribution centers. Foliar uptake of 32P rapidly involved in the metabolic process, the synthesis of a variety of inorganic organic phosphides, of which about 80% incorporation of acid-soluble components
