水稻纹枯病是我区水稻上的主要病害，８０年代以来一直呈偏重发生趋势，近１０年平均４级以上发生，对水稻生产影响极大。本文通过对１９９８年水稻纹枯病的发生特点及原因分析，认为气候条件、菌源、品种及栽培管理措施是影响水稻纹枯病发生的主要因子。在加强测报的基础上，科学管理、合理选用高效药剂是防治的关键。
Rice sheath blight is a major disease on rice in our district. Since the 1980s, it has been a trend that tends to be more and more serious. Over the past 10 years, an average of Grade 4 or above has occurred, which has a great impact on rice production. In this paper, by analyzing the characteristics and causes of rice sheath blight in 1998, it is concluded that climatic conditions, bacterial sources, varieties and cultivation management measures are the main factors that affect the occurrence of sheath blight in rice. On the basis of strengthening the measurement and reporting, scientific management and rational selection of efficient pharmaceuticals are the key to prevention and control.
