| Abstract: | Rhizosphere is commonly regarded as the volume of a thin layer of soil immediately surrounding the plant roots.Due to the microbe populations' interactions and the root activities in this region,the rhizosphere soil usually distinguishes significantly from the bulk soil,which is not influenced directly by living roots.To determine the magnitude of rhizosphere effect on different plants in arid region,a rhizobag experiment on five xerophytic plants of Haloxylon ammodendron,Haloxylon persicum,Salsola ruatheni... |
