摘　　要：通过大田试验研究不同产地沙枣在干旱胁迫下的生长特性,应用隶属函数法对这些材料进行了抗旱性评价,筛选出较为抗旱的沙枣。结果表明:不同产地沙枣的成活率、保存率、高生长量、地径、干物质积累量等指标均存在明显的差异;土左旗、乌海和民勤沙枣均容易成活和保存,抗旱性较强,能较好地适应干旱环境,可以作为抗旱优良种质资源进行造林推广。The field experiment was conducted to investigate the growth characteristics of Elaeagnus angustifolia from different producing areas under drought stress.The drought resistance of Elaeagnus angustifolia was evaluated by use of membership function method.The results showed that there were distinct differences among survival rate,preservation rate,height increment,ground diameter and dry matter accumulation of Elaeagnus angustifolia from different producing areas.Elaeagnus angustifolia from Tuzuo Qi,Wuhai and Minqin could easily survive and preserve,and could suit for the arid environment with strong drought resistance,which could be planted and popularized as fine drought-resistant germplasm in the arid region.
