1983年6月,我们在黄岩县新前乡前洋村金有树的承包桔园中,发观一种柑桔新病害,病树的症状和树脂病很不一致。根据其症状,暂称为裂皮流胶病。其特征是: 1.病势迅猛,树体主干下部开裂流胶,树皮裂缝沿一级主枝、二级、三级枝不断向上延伸。群众反映“裂缝一夜升半尺”,裂缝处产生流胶,流胶量较多。仔细观察树皮裂口,发现开裂的树皮和初生木质部分离、起翅,形成层坏死,裂口内部呈水渍状,手触有粘糊感。早期发病的枝条,树皮和初生木质部变为渴色,导致粗枝死亡,危及大枝,有的大枝死亡,树体生命受到威胁。
In June 1983, we found a new disease of citrus in the contracted orange garden of Jinyoushu, Qianyang Village, Xinqiang, Huangyan County. The symptoms of the diseased tree are very different from the resinous disease. According to its symptoms, tentatively called split leather gel disease. The utility model is characterized in that: 1. The disease is swiftly swollen and the lower part of the trunk of the tree is cracked and gelled; the bark crack extends along the primary branch, the secondary branch and the tertiary branch. The masses reflect “crack half a foot crack overnight,” cracks generated at the Department of plastic, plastic flow more. Careful observation of bark cracks and found that the bark rupture and primary xylem separated from the wing, the formation of necrosis, cracks within the water-like, hand touching a sense of sticky. Early incidence of branches, bark and primary xylem became thirsty, leading to dead branches, endangering large branches, some large branches die, tree life threatened.
