摘　　要：高山红景天（ＲｈｏｄｉｏｌａＳａｃｈａｌｉｎｅｎｓｉｓＡ．Ｂｏｒ）为长白山珍贵稀有的药用植物，有神草之称，是我省一级保护植物．本文主要记述一年生高山红景天幼苗在龙井地区对氮、磷、钾的反应，采用正交区组二次回归旋转组合设计进行试验，试验结果根长及根重的差异显著，但需肥量不多，瘠薄地适当施氮磷肥能促进根系生长，其模型为：Ｙ根重＝８．７６９５－０．８３３２ｘ１－１．２０２６ｘ２－０．７２２８ｘ３－０．６５６３ｘ１ｘ３－０．２９６２ｘ－０．３４８７ｘ＋０．６７１２ｘ．Rhodiola Sachalinensis is a precious and race medicinal plant in Changbai Mountain called supernatural grass, is one-level protected plant in Jilin province. The thesis Studied the reaction of annual seeding to N、P and K, the experiment was carried adopting the rotary society of the secondary regression of orthogonal block. The result showed: the different between root length and root weigh was sighnificiant, but its fertilizer demand wasn't great. Properly applying N、P and K can
