摘　　要：对不同种源地引进的抗寒耐盐碱美国白蜡进行了盐碱地造林试验研究,通过分析树木长势和改土效果来筛选出优良的白蜡种源。结果表明:中度盐碱地不同种源地引进的白蜡树木长势强弱依次为宾夕法尼亚>纽约>CK>威斯康星>田纳西>路易斯安那;轻度盐碱地则是明尼苏达>肯塔基>CK>亚拉巴马>密西西比。轻、中盐碱地不同种源地引进的白蜡对土壤改良作用与树木长势规律一致;中度盐碱地造林优选白蜡种源地为宾夕法尼亚和纽约,轻盐碱地则是明尼苏达和肯塔基2个种源地。Forestation of cold resistance and saline-alkali tolerant Frascinus americana from different regions in germination stage in salt soil were conducted, the fine Fraacinus americana were selected through the trees growth and soil amelioration effects. The results showed that growth and soil amelioration effects of Fraxinus americana in different regions in germination stage planted in the moderate saline-alkali soil were Pennsylvania 〉New York 〉CK 〉Wisconsin 〉 Tennessee 〉 Louisiana;and planted in the light saline-alkali soil were, Minnesota 〉 Kentucky 〉 CK 〉 Alabama Mississippi. Growth and soil amelioration effects of the Fraxinus americana in different regions in germination stage in light and moderate saline-alkali soil were consistent. The fine Fraxinus americana planted in the moderate saline-alkali soil were Pennsylvania and New York, and the fine Frazinus americana planted in the light saline-alkali soil were Minnesota and Kentucky.
