水稻白叶枯病在我省40年代有过调查,解放初期也有过报道.但自60年代以来,随着高产品种的推广和施肥水平的提高,此病有明显的发展,成为生产上的重要问题.推广抗病良种是对水稻白叶枯病综合防治中带根本性的措施.而水稻白叶枯病菌系研究则是水稻品种的抗性鉴定、抗病品种选育和合理布局的重要基础工作. Rice bacterial blight has been investigated in the 1940s in our province and has also been reported in the early days of liberation, but since the 1960s, with the promotion of high-yielding varieties and the improvement of fertilization levels, the disease has been markedly developed and has become an important production The promotion of disease-resistant varieties is a fundamental measure in the integrated control of bacterial blight in rice, while the study of bacterial blight in rice is an important basis for resistance identification, breeding of resistant varieties and rational distribution of rice varieties jobs.
