| 摘 要： | 通过＾１５Ｎ示踪微区试验，研究西洋参氮素营养特性。结果表明：１５＾Ｎ－尿互在西洋参各器官均有分布，参朱从肥料中吸收氮素（ＮＤＦＦ％）含量地上部各器官高于地下部。施氮肥与未施氮肥处理的收获参根干重为２８．８９％和２１．８２％；施氮肥增加了参根蛋白氮和非蛋白氮的含量，并约有８０％＾１５Ｎ分配到参根蛋白氮中。

| Abstract: | Nitrogen nutrition of Panax quinquefolium Linne was studied by using 15N tracer technique. The results showed that 15N (15N-urea) was distributed to all organs of Panax quinquefolium Linne. NDFF％ in above-ground part was higher than that in below-ground part.Root dry weight was 28.89％ and 21.82％ respectively for treatments with or without nitrogen application. The application of nitrogen fertilizer increased the content of nitrogen in both protein and non-protein forms and about 80％ of the nitrogen was found in root protein. |
