摘　　要：甘蒙柽柳(Tamarix austronongolica Nakai)是优良的水土保持树种。通过不同条件下进行的甘蒙柽柳扦插造林试验,结果表明:在春季用甘蒙柽柳进行扦插造林时,上端覆盖虚土的插穗的成活率显著高于不覆土的插穗;新修筑的地埂上的插穗成活率显著高于修筑2年以上地埂的插穗的成活率;30cm、25cm的插穗成活率与15cm插差异显著,可通过增大长度为15cm的插穗的造林密度以满足造林需要。Tamarix ramosissima is an excellent tree species for soil and water conservation.Afforestation experiments of Tamarix ramosissima cuttings were conducted under different conditions.Result shows that the survival rate of Tamarix ramosissima cuttings were covered with porous soil is higher than that without covering soil in spring.The survival rate of cuttings on the newly-built ridge was significantly higher than that on the ridge which was built two-years ago.The survival rate of cuttings with the length being 30 cm 25cm was significantly different from that of cuttings with the length being 15 cm.The afforestation density of cuttings with the length of 15 cm can be increased to meet the afforestation needs.
