| Abstract: | We examined the hydraulic lift function of 21 psammophytes and clarified the characteristics of this process in the Horqin sandy land,Inner Mongolia.We used self-made growth boxes,in which the soil was separated into upper and lower layers by Vaseline.The water supply to the upper soil was controlled during the examination period.We determined the hydraulic lift effects by measuring the variation of soil water content in the upper soil.Results showed that the hydraulic lift process occured mostly during 00:... |
