AbstractThis paper carried out research on the key technologies for dryland planting of Corethrodendron fruticosum var.lignosum in the Mu Us Sandy Land. It mainly discussed the influences of sedling diameter grade，planting time，planting method，collection area and preservation method，and planting location on the survival rate and growth status of Hedysarum mongolicum.The results showed that： in gentle sandy land， planting one-year-old bare-root seedlings with a ground diameter of 0.25-0.35cm in April has the highest survival rate of 83.3% in that year. In the comparison of different planting times， the survival rate of seedlings planted in April is the highest at 84.3% . In May， the survival rate drops to 64.8% . In June， the survival rate is low， only 37% ，which is no longer suitable for planting under local dryland conditions. Different planting methods have no significant influence on growth indicators，and the survival rates are all above 70% . Compared with cold storage seedlings from Otog Front Banner and freshly collected seedlings from Otog Front Banner，cold storage seedlings from Hangjin Banner have bettr later growth and the highest survival rate of 81.5% ，which are suitable for seedling planting in such areas. The survival rate of seedling planting in the middle of the windward slope of low sand dunes can reach up to 88.9% . At the bottom of the slope， 80.2% can meet the survival rate requirements for the planting year. However， at the top of the slope， the survival rate is only 66.7% ， which is not suitable for dryland planting.
