摘　　要：2008年,辽宁省大连市经济开发区(现金普新区),在通往金石滩的主路中间绿化带上栽植了300余株大雪松,从第二年开始,这些雪松逐渐出现了枯头、枯枝、枯叶等现象,最终死亡,造成巨大经济损失的同时还给原产地和栽植地的生态造成了严重的破坏。2018年此种现象再一次出现在大连地区星海人家小区里的雪松上,经过整理大量科研资料以及实地考察确定该批雪松系感染子囊菌亚门的茶簏子葡萄座腔菌(Botro-sphaeria ribis)所引起的雪松枯枝病,亦称为雪松叶枯病。确认病情后,随即对现场的雪松展开救治,采取常规治疗措施的同时,还第一次投入了“那氏778”诱导剂灌根扶壮法,实验效果显著持久。In 2008,more than 300 Cedrus deodara,commonly known as deodar cedars,were planted on the green belt in the middle of the avenue leading to Jinshitan in Liaoning Province,more specifically in Jinpu New District’s Dalian Economic Development Zone.From the second year onward,the upper tips,branches and leaves of these Cedrus deodara gradually withered before eventually dying,causing huge economic losses and serious damage to the ecologies in both the region of nativity and planting area.In 2018,this phenomenon re-appeared on the Cedrus deodara in Xinghai Renren community in Dalian.After sorting out massive amounts of scientific research data and field investigation reports,the etiology of twig blight suffered by these Cedrus deodara was confirmed to be an infection by Botrosphaeria ribis,which is a species under the Ascomycotina phylum known for causing leaf blights.Having confirmed the etiology,on-site rescue was carried out as soon as possible.In addition to the regular treatment routines,this study also pioneered the adoption of plant strengthening through root irrigation using Nashi 778 growth inducer.The efficacies of the experimental treatment were found to be significant and lasting.
