The trials on cultivation of Atriplex canescensconducted in Minqin Desert Control Experiment Station reveals that this speciesentails fine qualities as strong tolerance in drought, cold, salinity and low temperatureas well as high annual biomass. So it cab be extended in sandy areas with favorableirrigation condition, and on hilly in loess plateau with relatively high rainfall and lowevaporation. As a new substitute species for water/soil conservation and rangelandregeneration, it has a big potential to be extended. However, more research on withinwhich scope this species can be extended need to be done
