沙枣在吉林苏打盐碱土区的适应性研究

Research on the adaptability of Elaeagnus angustifolia L. in saline sodic soil areas of Jilin province

以甘肃张掖、新疆塔城、内蒙古巴盟磴口、加拿大埃德蒙顿地区生长的沙枣为种源,在吉林省西部苏打盐碱土区经过7 a引种栽培试验,结果表明:4个种源之间的物候期无明显差别,且与引种地相差不大;当年成活率达到90%以上,未发生盐害;株高、根径生长与引种地虽然存在一定差距,但差异不显著;加拿大、新疆、内蒙古种源可以自然越冬,甘肃种源越冬率在80%左右;未见明显病虫害。沙枣在吉林苏打盐碱土区具有良好的生长表现和适应性。

Elaeagnus angustifolia L.growing in Zhang ye,Gansu province, Tacheng, Xinjiang province, Bamengdengkou, Inner Mongolia and Edmonton , Canada were taken as provenances by 7 a introduction and cultivation test in saline sodic soil areas of west Jilin province .The results showed：phenophase among 4 provenances indicated no significant difference , and was also no significant difference with provenance .The survival rate of current year was more than 90%, salt damage was unhappened .There were non-significant differences of plant height and root diameter growth between cultivations and provenances;provenances of Canada , Xinjiang province and Inner Mongolia could overwinter naturally , overwintering rate of Gansu was about 80% without obviousplant diseases and insect pests .Elaeagnus angustifolia L.showed favourable growth performance and adaptability in saline sodic soil areas of Jilin province .
