【摘要】 对沙柳、刺槐等14个树种在不同盐碱地块进行造林试验,调查分析其成活、生长及受害情况,根据抗盐性=盐分胁迫/由该胁迫所导致的胁变原理,采用单一和多个形态指标相结合的方法对试验树种的抗盐性进行了评价。结果表明:紫穗槐、绒毛白蜡、侧柏、沙柳、桑树等抗盐性强,应作为黄河三角洲地区盐碱地造林的首选树种;而毛桃、山杏等树种抗盐性弱,不能用于盐碱地造林。提出树种耐盐性评价必须结合不同盐碱地类型进行。更多还原

【Abstract】 Afforestation experiment were conducted in different saline-alkali soil on 14 tree species such as Salix psammophila and Robinia pseudoacacia L.etc.,their survival,growth and victimization were investigated and analized.According to the principle of salt-resistance = salinity stress/transformation caused by the threat,salt resistance of the test species were evaluated by single and multiple morphological index.The results showed that Amorpha fruticosa,Fraxinus velutina,Platycladus orientalis,Salix psammophila,Morus alba’s salt resistance were stong,should be the preferred species for afforestation in saline-alkali soil in the Yellow River Delta region;while Armeniaca sibirica,Amygdalus persica ’s salt resistance were weak,could not be used for afforestation in saline-alkali soil.It was proposed that tree species evaluation of salt tolerance must be combined with different types of salinealkali soil.更多还原
