我国关于水稻条纹叶枯病的研究报道甚少。我们曾在1967—1968年对该病作过研究,后因病害减轻,研究工作暂停,1981年起发病增多,故又开展本项研究。现将几年来的研究结果总结如下。 (一) 病害历史和分布水稻条纹叶枯病我国似早已存在,但其发病情况无文献记载。最早于1964年朱凤美等报道:1963年浙江余姚、慈溪县及上海和苏南等地黑条矮缩病大流行,同时有少最条纹叶枯病发生。以后发病地区和面积明显扩大,1966年浙江省嘉善、海宁等县单季晚稻平均株发病率达10.3％(3.7—20.8％),1969年后发病减轻。到七十年代中、后期本病又开始回升,近年来在江、浙、沪一些社 There are few reports on rice stripe disease in our country. We studied the disease from 1967 to 1968. After the disease was alleviated and the research was suspended, the incidence increased since 1981. Therefore, we conducted this study again. The results of several years are summarized below. (A) the history and distribution of rice stripe disease Rice stripe like a long time ago in our country, but its incidence was not documented. The earliest in 1964, Zhu Fengmei et al reported: 1963 Yuyao in Zhejiang Province, Cixi County and Shanghai and southern Jiangsu and other places black-striped dwarf disease pandemic, at the same time there is less stripe rust stripe occurred. After the onset of the area and the area was significantly expanded in 1966 in Zhejiang Jiashan, Haining and other single-season rice average annual incidence rate of 10.3% (3.7 - 20.8%), after 1969 reduced incidence. To the mid-seventies, the disease began to rebound later, in recent years in Jiangsu, Zhejiang, Shanghai and some clubs
