基于上海地区水稻条纹叶枯病普查资料，分析整理显示：水稻条纹叶枯病的发生程度与灰飞虱的越冬代虫量基数、播期、种植方式及品种自身抗性有一定的关系。灰飞虱越冬代虫量基数与冬季的温度呈显著的正相关（r ＝0．7227*）；在5月1日至6月10日，播期越早，条纹叶枯病发病程度相对越重，与播期存在明显的指数关系（y ＝43．614e －0．867x ，R2＝0．9918**）；直播稻的发病率要高于移栽稻，品种间条纹叶枯病的抗性有明显差异。

Based on the surveyed data of rice stripe disease in Shanghai suburbs,the analytical results showed that the rice stripe disease occurrence degree had certain relations to the quantity of overwintering Laodel-phax striatellus,rice seeding date,planting methods and variety’s resistance.The quantity of overwintering L.stri-atellus had a significant positive correlation with temperature in winter (r =0.7227 *);In May 1 to June 10 peri-od,the earlier the seeding date,the relatively heavier the rice stripe disease,there being an obvious exponential function relationship between the rice stripe disease index and the seeding date (y =43.614e -0.867x,R2 =0.9918 **);The disease incidence of direct-seeded rice was higher than that of transplanted rice,and the differ-ence of rice varieties in rice stripe disease resistance was also obvious.
