Salix psammophila in use for revegetation of semi-arid regions in China is said to be going to fade awayalong with the invasion of other plants after it fixed the sands. In fact, in order to know how the growthof Salix psammophila was subjected to the influences under the competition with other plants, Salixpsammophila was allowed to be mingled with weeds or with cosmos which was assumed as a weed. Whenthe amount of weeds increased and the density of cosmos was elevated, the attained total lengths of shootwhich grew newly became shorter and the dry weight of surface/underground part decreased. And the casein which mortality was elevated was seen. What was characterized was that the attained dry weight ofsurface part of Salix psammophila in a 1/2, 000a Wagner pot was reduced to about 1/3 and the dry weightof underground part (root) was reduced to about 1/2 even though one cosmos was mingled with Salix psammophila compared with that of Salix psammophila without the mingling. As above, it was confirmedthat Salix psammophila is a typical pioneer plant that remarkably reduced the growth when it was mingledwith other plants. T/R ratio was also reduced as the increase of weeds and cosmos. From the abovefindings, it was considered that the competition due to the mingling occurred mainly at the undergroundpart, and that it was the manifestation of a relative increase in the amount of root.
