Results of the orthogonal experiment of N, P and K are as follows: (1) The highest growth rate occurs in treatment 4 (N100ppm, P25ppm, K250ppm) and other features are also good. So this treatment can be used in hydroponics of seedling of P. quinquefolium. (2) The influences of N, P and K concentration on the contents of ginsenosides in different parts of seedling are different. The content of ginsenosides in aerial part is 14.72-16.72%, higher than 3.24-4.00% in root.
氮、磷、钾正交试验结果如下：（1）处理4（氮100ppm、磷25ppm、钾250ppm）生长速率最高，其他性状也良好。因此该处理可用于西洋参幼苗水培。（2）氮、磷、钾浓度对幼苗不同部位人参皂苷含量的影响不同。地上部分人参皂苷含量为14.72 - 16.72%，高于根部的3.24 - 4.00%。
