田间病状观察和指示植物测定表明:在我省柑桔产区已经发生柑桔裂皮病。1984～1986年调查了7个地区21个柑桔主产县的131个栽培品种,发现4个县的18个栽培品种发生此病,各品种发病率为10～100％。我省主栽品种以及柚、枸橼、金柑类各品种尚未发现田间的典型病状。但进一步采用指示植物Etrog香橼Arizona 861或861-S-1以及爪哇三七(Gynura aurantiaca)鉴定,发现我省主栽品种福桔、温州蜜柑、芦柑、雪柑、改良橙、新会橙等,虽多无表现典型的田间病状,但均已感染裂皮病,属隐症带毒现象。该病现分布在我省的福州、闽清、建阳、建瓯、沙县、永春、漳州、漳浦、南靖等9个县(市)。病原CEV存在毒系的差异。加强检疫,挖除病株是防止我省柑桔裂皮病蔓延为害的关键,此外,还应注意修枝剪等工具的药物消毒处理。
Field observation and indication of plant pathology showed that: in our province citrus production area has occurred citrus split disease. From 1984 to 1986, 131 cultivars from 21 citrus-dominated counties in 7 regions were investigated. The disease was found in 18 cultivars in 4 counties with the incidence of 10-100%. The main cultivars in our province as well as pomelo, citron, kumquat varieties have not found the typical symptoms of the field. However, further identification with plant Etrog citron Arizona 861 or 861-S-1 and Gynura aurantiaca indicated that the main cultivars of Fuchu, Wenzhou Satsuma, Citrus, Citrus, Orange, Xinhui Orange Although no typical symptoms of the field, but have been infected with split-skin disease, is a hidden phenomenon of poisoning. The disease is now distributed in 9 counties (cities) in Fuzhou, Minqing, Jianyang, Jian’ou, Shaxian, Yongchun, Zhangzhou, Zhangpu, and Nanjing in Fujian Province. Differences in virulence of pathogenic CEV exist. Strengthening quarantine and digging diseased plants are the key to preventing the spread of citrus split disease in our province. In addition, we should pay attention to the drug disinfection of pruning shears and other tools.
