摘　　要：树附生苔藓对附生树的危害研究甚少,对果树的危害认知不足。通过调查陕南柑桔主产区城固、汉台等地的柑桔园,盛果期丰产园柑桔树附生苔藓感染指数近80%,年柑桔树致死率最高达2.99%,并随树龄增加而加重之势明显。从植物病理学角度出发,研究柑桔树附生苔藓地衣危害过程、症状表现、分级方法、发生规律及原因等方面,提出防治措施,为柑桔生产中苔藓地衣的防治提供参考。Very few studies were reported on the harm of tree epiphytic bryophytes to epiphytic trees,and the cognition of its harm to fruit trees is limited.According to the survey in citrus orchards in Chenggu county and Hantai District of Hanzhong,the infection index of epiphytic lichen on citrus trees was nearly 80%,and the mortality rate was up to 2.99%,which increased with the increase of tree age.From view of plant pathology,the damage process,symptoms,classification,the occurrence regularity and reasons of epiphytic lichen on citrus trees were studied in this paper,the prevention and control measures were put forward.This study provided a reference for the prevention and control of lichen in citrus production.
