摘　　要：试验结果表明,当营养型参地土壤保水剂用量为10 kg·m-2时,土壤相对含水量苗期增加18.8%,结果期增加15.4%,根增重期增加12.6%,人参保苗率增加18.4%,达到显著或极显著标准;参根皂苷含量较对照增加11.4%,茎皂苷含量增加11.5%,叶片皂苷含量增加10.8%,达到显著标准;人参产量较对照增加21.5%,差异达到极显著标准。The results showed that when the nutrition type water retaining agent was 10 kg·m-2,relative soil water content was increased by 18.8%,15.4% and 12.6% in seedling stage, fruiting stage and root fast growth stage, The survival rate of Ginsengs, which were applied nutrition type water retaining agent, was increased by 18.4%, and there were significant and extremely significant difference from that of control. Application of nutrition type water retaining agent could improve saponin content in roots, stems and leaves of Ginseng by 11.4%,11.5% and 10.8% respectively,compared to the control, and the difference reached significant level; The outputs of Ginseng increased 21.5% than the control, the difference reached significant level.
