摘　　要：准噶尔盆地南缘咸水资源丰富,尝试用高矿化度咸水补充灌溉耐盐性荒漠植物柽柳,对区域非常规水高效利用和荒漠植被恢复意义重大。通过5个矿化度梯度(13.2、19.2、23.2、27.2、31.2 g/L)咸水灌溉试验,结果表明:高矿化度咸水对于柽柳的生长有明显的抑制,抑制程度与矿化度成正相关,但对于冠福却又有促进作用;叶盐含量随着矿化度的升高而升高,而地上部分的干鲜比随着矿化度的升高而降低;27.2 g/L以上(包括27.2 g/L)的咸水灌溉会致使柽柳提早结束生育期,但没有致死现象发生。这为准噶尔盆地南缘咸水资源的高效利用和荒漠生态的恢复提供理论依据。The saline water resources are abundant in the southern edge of Junggar Basin,try,it is great significant for regional non-conventional water efficient use and desert vegetation to try using saline water with high mineralization degree to supplement irrigating high salt tolerance desert plants Tamarix.The results of salt water irrigation with 5 salinity gradients（13.2,19.2,23.2,27.2,31.2 g/L） show that high salinity water significantly will restrain the growth of tamarisk and the restraining degree is positively correlated with the mineralization degree,while will promote the crown.The salt content in leave will increase with the increase of salinity,however,the above ground ratio of dry and fresh will increase with the decrease of mineralization degree.The saline water irrigation with mineralization degree of 27.2 g/L or more will result in early termination of tamarisk growth period,but no death occurred.The result will provide technical support for salt water use and ecological restoration in the southern edge of Junggar Basin.
