摘　　要：以人工接种的方法研究了水稻纹枯病对佳辐占再生力的影响。结果表明,水稻纹枯病主要影响佳辐占倒3和倒4芽的再生力,降低再生季的穗茎比,导致再生季的有效穗减少,从而影响再生季产量。In this paper, the effect of Jiafuzhan ratooning ability research was conducted by artificial inoculation of sheath blight（Rhizoctonia solani）. The results showed that sheath blight mainly affected ratooning ability of Jiafuzhan at the 3th and the 4th nodes from top and therefore it reduced panicle-stem ratio and panicle numbers, which resulted in low yield in ratooning cropping.
