[目的]促进药用植物北沙参在华东地区栽培应用。[方法]以北沙参幼苗为试材，正交设置北沙参营养生长期光、肥、水三因素的不同水平处理，检测其生物生长量、叶绿素含量和丙二醛含量等多项指标。[结果]北沙参人工栽培的最适条件与其野外生存环境并不完全一致。轻度遮荫、高肥（21.38～32.08 g）和适当灌水（500～750 ml）条件下北沙参生物量明显增加，叶绿素和胡萝卜素含量增加，丙二醛含量无明显变化；逆境条件栽培的北沙参生物量较小，叶绿素与胡萝卜素含量下降，叶绿素 a含量对光、肥、水等环境因子的变化更为敏感，且逆境栽培的北沙参叶片丙二醛含量显著升高。[结论]轻度遮荫、高肥和适当灌水是北沙参生长的最佳条件。

The aim was to promote the cultivation and application of medicinal plants Glehnia littoralis. [Method] Glehnia littoralis was used as experi-mental materials in this study, and orthogonal design was performed to investigate the effects of light, fertilizer and irrigation on the growth of Glehnia littoralis. The biomass, leaf chlorophyl and malondialdehyde (MDA) content were determined to study its response to light, fertilizer and irrigation. [Result] The results showed that the optimum cultivation conditions of Glehnia littoralis were not completely consistent with wild living environments. Lightly shade, highly fertilization (21.38-32.08 g) and proper irrigation (500-750 ml) were suitable for artificial cultivated Glehnia littoralis. Under the condition, the biomass was enhanced, leaf chlorophyl and carotene con-tent were increased, and MDA content changed significantly. Under stress condi-tions, the biomass of Glehnia littoralis reduced, with the decrease of chlorophyl and carotenoid content. The content of chlorophyl a was more sensitive to the variation of light, fertilizer, irrigation and other environmental factors, and MDA content signifi-cantly increased by stress conditions. [Conclusion] This research can provide refer-ence for large-scale artificial cultivation of Glehnia littoralis.
