摘要
丝棉木是一个抗旱性和耐盐性较强的树种，对它的保水力、水势、水分亏缺、蒸腾强度等抗旱生理进行了测定，除临界饱和亏一个指标不如沙枣和洋槐外，其余指标均强于抗旱性较强的沙枣和洋槐。丝棉木对自然复合盐的耐盐程度可达２．５％以上，对四种单盐的耐盐极限为１．１％。
Euongmus bungenus Maxim is a kind of tree species with high drought resistance and salt tolerance. This paper determined its moisture preservation, water flow, moisture loss and transpiration intensity. Besides the critical saturation,the other indexes are all higher than Elaeagnus angustifolia and Sophora.
