| 摘 要： | 通过对不同栽培密度与水稻纹枯病的发生、发展之间的关联进行田间试验研究。结果表明，在同是30.0cm×13.2cm插秧规格的条件下，随着穴株数的增加纹枯病发病程度呈递增趋势，4株／穴时病情指数为0.68、6株／穴时病情指数为0.96、8株／穴时病情指数为1.72、10株／穴时病情指数为2.02。

| Abstract: | Based on the different planting density associated with the occurrence and development of rice sheath blight on experiment research in field. The results indicated, on the condition of the same planting 9×4 specifications of the conditions, sheath blight disease happened Increasing with the increase of point density, with 4 plants per point disease index was 0.65, and 6 plants per point disease index was 0.96, 8 plants per point disease index was 1.72, 10 plants per point disease index was 2.02. |
