水稻白叶枯病,从明治年间在福冈县发现以来,现在成为九州稻作的主要病害之一。目前机械插秧迅速普及,机插后要灌水护苗,而白叶枯病菌又是以水为媒介进行传播的,所以更加速了白叶枯病菌的传染,其危害更加严重。1957年在九洲北部种植的抗性较强的品种“朝风”突然发病之后,对白叶枯病菌系分类进行了研究。白叶枯病抗性和其他病害一样,分真性抗性和圃场抗性两种,尤其是圃场抗性是今后研究的重点。
Rice bacterial leaf blight, which was discovered in Fukuoka Prefecture during the Meiji era, is now one of the major diseases of rice in Kyushu. At present, the rapid popularization of mechanical transplanting rice seedlings after machine plugging, and bacterial leaf blight is water as a medium for transmission, so more rapid transmission of bacterial leaf blight, its harm is even more serious. After the sudden onset of the “Asteroid” disease, which was cultivated in the northern part of Jiuzhou in 1957, the bacterial taxonomy of the bacterial blight was studied. Bacterial blight resistance Like other diseases, both true resistance and nursery resistance, especially nursery resistance, are the focus of future research.
