近年来,我国在推广种植矮秆品种、杂交稻组合以及提高密植程度和施肥水平后,纹枯病为害明显加剧。当前,在防治上运用栽培技术与药剂相结合的措施,收效显著。但从长远的观点来看,培育抗病品种是防治水稻纹枯病最经济、有效的方法[1、6]。因此研究品种抗性的鉴定技术,开拓水稻纹枯病抗性种质,鉴定当前生产上常规品种的不同抗感程度,这在今后纹枯病的防治对策上,具有重要的意义。
In recent years, the promotion of dwarf varieties, hybrid rice combinations and to improve the degree of close planting and fertilization levels, the sharp increase in sheath blight disease. At present, the combination of cultivation techniques and medicaments in prevention and treatment has achieved remarkable results. However, in the long run, cultivating disease-resistant varieties is the most economical and effective way to control rice sheath blight [1,6]. Therefore, it is of great significance to study the identification of resistance to varieties, to develop resistant varieties of rice sheath blight, and to identify the different resistance levels of conventional varieties on the current production. This is of great significance in the prevention and control of sheath blight in the future.
