摘　　要：为了摸清人参菜人工种植的适宜条件,提高种植效益,探索适合发展种植模式,对人参菜进行了种植试验。通过进行不同光照强度的试验对比,得出如下结果:人参菜种植时,不遮荫(全光照)条件有利于人参菜成活率、叶片数、叶绿素、鲜重、膳食纤维的增加;一层遮阳网(25klx)条件下有利于人参菜株高、最大叶长的增加;两层遮阳网(6.25klx)对人参菜生长指标无显著差异。In order to find out the suitable conditions for the artificial planting of Talinum trianglare,improve the planting efficiency and explore the suitable planting mode,the planting experiment of Talinum trianglare was carried out. Through the experiment of different light intensity,the following results were obtained:when Talinum trianglare is planted,the non shading(full light)condition is conducive to the increase of survival rate,leaf number,chlorophyll,fresh weight and dietary fiber of Talinum trianglare;one layer of shading net(25 klx)is conducive to the increase of plant height and maximum leaf length of ginseng;there was no significant difference in the growth index of Panax ginseng between the two layers of shading(6.25 klx).
