Abstract: The study is conducted in Yanchi county situated at the southweastern rim of Mu Us Sandy Land. The annual precipitration in the studied area is about 200-300 m, and wind blows frequently. In order to raise the save rate, survival rate and growth rate of improved shrub varietites in sandy area, 16 species of shrubs such as Hedysarum frulicosum Pall., H. leave Maxim. and Artaphaxis bracteata A. Los. etc. are tested for asking for the technology of breeding and culturing. The studing contents consist of seed treatment, period and method of breeding, thickness of soil cover, management in nursery; selection of site conditions, soil tillage before planting, depth of planting, species disposition, planting method and rejuvenating method etc.. A set of breading and culturing technology have been put forword. In details, the breading technology mainly include bud forcing treatments, growing seedlings in the first ten day period of May, 0.5-1 cm soil cover for smaller seeds, about 2 cm for medium size seeds and 3-4 cm for bigger seeds, as well as preventing soil hardening and wind erosion; the planting technology are that of based on ecological feature of each species to select suitable type group, to even land for one or two times before planting, depth of planting should be 50-70 cm and establish mixed forest; the rejuvenating technology comprise regullarly rejuvenation to promote shrub growing and increase its biomass, leaving stuble even with ground or deep into surface about 2 cm, deciding rejuvenating period by biological features and utilization value of each shrub.
