水稻白叶枯病一九六七年首先在彭县利安公社三合一队发现,全省主要稻区也先后发生,使水稻产量受到很大损失。病轻的减产10～20％,病重的减产50％以上。从一九七○年起,我所深入该队蹲点,开展群众性的科学实验,总结推广了适合当地情况的综合防治措施,基本上控制了白叶枯病对水稻的危害。主要经验是贯彻了以抗(耐)病品种为基础,秧田防治为重点,加强肥水管理等一套综合防治措施。具体作法是: 一、选用抗(耐)病品种和无病良种全县种植耐病品种“窄叶青8号”十多万亩,占中稻总面积的30％左右,三合一、
Rice bacterial leaf blight First discovered in Pengli County Li’an Commune in 1967, the main paddy areas in the province also occurred one after another, causing great losses in rice production. Slight loss of 10 to 20% of the disease, serious reduction of 50% or more. Since 1970, I have gone deep into the team to carry out mass scientific experiments and summarized and popularized comprehensive prevention and control measures suitable for the local conditions, basically controlling the harm of rice leaf blight to rice. The main experience is the implementation of a comprehensive anti-(resistant) disease-based varieties, seedling prevention and control as the focus, to strengthen fertilizer and water management and a comprehensive set of prevention and control measures. The specific practices are: First, the selection of resistant (resistant) varieties and disease-free elite varieties of resistant varieties of the county planted “Narrow Yeqing 8” more than 100,000 mu, accounting for about 30% of the total area of rice, triple,
