摘　　要：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。The result showed that green fruit period of 5 yr old ginseng provided P by the surface of leaves. The mean of absorption rate is 21.92% during 36 days.The distribution centres are fruit and root which are growing up.The 32 P which was absorbed by the surface of leaf begain go into metabolism quickly and changed from inorganism into many kinds of organic phosphide.
