Abstract Salix psammophila is one of the important biological and ecological resources in Hobq Desert. Experiment for three years showed that compared to a control the treatments of rootone (ABT), water retention agent and manure application, and a planted density of four individuals in each hole, could significantly improve the survival rate, height, basal diameter, biomass production and sprouted branch number of Salix psammophila. Cutting in combination with water retention agent could greatly increase the survival rate, biomass and sprouted branch number significantly (P<0.05) by 61.0%, 70.4% and 71.4%, respectively. Any of these four treatments could be adopted as a means to promote Salix psammophila production.
