2003～2004年定点调查表明,水稻条纹叶枯病在秧苗期主茎显症后,同株的分蘖全部显症,病株死亡。分蘖期主茎显症后,同株的分蘖全部显症;部分分蘖显症后,同株的主茎和其余分蘖全部显症,病株死亡或不成穗。拔节期主茎显症后,同株的大部分分蘖(68.9%～79.2%)显症,部分茎、蘖(32.9%～23.0%)成穗,产量损失较大(80.8%);部分分蘖显症后,同株的主茎不显症,其余分蘖部分显症(分蘖总显症率为53.0%～66.7%),全部主茎和部分分蘖成穗(总成穗率61.1%～48.1%),产量损失较小(34.5%)。病株不侵染同穴健株。由此提出治虫防病、改茬和病后处理方法。
The survey conducted from 2003 to 2004 showed that all the tillers in the same strain of the rice stripe disease were dead and the diseased plants died after the main stalk of the rice stripe disease was observed in the seedling stage. After tillering, the tillers of the same strain all showed obvious symptoms. After partial tillering, all the main stems and the remaining tillers of the same strain were all displayed disease, and the diseased plants died or were not formed as spikes. Most of the same tillers (68.9% -79.2%) showed symptoms with some stems and tillers (32.9% -23.0%) forming ears with large yield loss (80.8%) after tillering stage. After the disease, the same strain of the main stem is not significant, the remaining part of the tillering symptoms (total tillering rate of 53.0% ~ 66.7%), all the main stem and part of the tiller into the ear (total spike rate 61.1% ~ 48.1%) , Less yield loss (34.5%). Strain does not invade the same hole with strains. Proposed pest control disease, stubble and disease treatment methods.
