| 英文简介 | Reaumuria soongpric is widely distributed in the different habitat of China such as Zhungeer, Talimu, Chaidamu, Centry gebi, Alashan. Reaumuria soongorica's desert have very dry and saline soil. Reaumuria soongorica is flourish in this area .There are zonal grey-brown desert soil and residual saline soil exist accompany.The desalinate layer of soil profile is from 0 to 30cm， the principle root of Reaumuria soongorica distribute in this layer;The salinzed layer of soil profile is from 30cm to 70 cm, it's salt content is more than 1%,there are more branch roots and thin roots. So we think Reaumuria soongpric could ues the water of salinzed layer of soil. Survey and measure soil profile characteristics ,water content，salt content, salt consititute of Reaumuria soongorica's desert , use Isotopic Element to test the water souce of Reaumuria soongorica; Survey and measure root anatomic structure, root system architectures and root hydraulic conductance, to analyze how Reaumuria Soongorica absorb water from soil , study the absorbing mechanism of Reaumuria Soongorica through those experiments.The study could expand the water use research on plant,it also could provide some science basis conclusions for developing new germplasm and gene source of antidrought and antisalty plant. |
