Seed germination status of Saussurea involucrata (Kar. et Kir.) Sch.-Bip. was compared by setting two groups of sowing depth according to 0.5 and 0.2 cm gradients. The results show that under sowing depth of 0.0-4.0 cm (0.5 cm gradient) and 0.0-2.0 cm (0.2 cm gradient) conditions, germination energy and germination rate of S. involucrata seed appear a trend of increasing firstly and then decreasing with increasing of sowing depth, and suitable sowing depth is 1.0 and 1.5 cm, 1.0 and 0.8 cm, respectively, in which, seed germination rate is obviously significant higher at sowing depth of 1.0 cm than that at other sowing depths.It is concluded that the suitable sowing depth ofS. involucrata seed is 0.8-1.5 cm. Combined research and planting experience in recent ten years, it is suggested that the best sowing depth of S. involucrata seed is 1.0-2.5 cm in loose soil of arid region and that is 0.5-1.0 cm in tight soil.
