水稻细菌性条斑病的发生为害 水稻细菌性条斑病在水稻任何生长时期和任何环境条件下都可以发生为害,其中以苗期、分蘖盛期、孕穗期发病最重。从晚造发病情况看来:发生期长,水稻全生长期都可以发病;病源残存时间长,能重复侵染次数多。水稻一经发病后,病菌就不断侵染,不断形成新病斑,有时当水稻新叶还未完全抽出,已被病菌侵入,形成油渍状透明斑,5—7天后病斑呈褐色透明条状,并且开始分泌大量细菌溢
Rice bacterial leaf streak damage occurs Rice bacterial leaf streak can occur in any rice growth stage and under any environmental conditions, of which the seedling stage, the tillering peak, booting the most severe. It appears from late onset situation: the occurrence of a long period, the rice can all disease growth stage; pathogen survived for a long time, repeated infections more often. After the onset of rice, bacteria continue to infect, continue to form a new lesion, and sometimes when the new rice leaves have not been fully extracted, has been invaded by bacteria to form a transparent plaque stain, 5-7 days after the lesions were brown transparent bar, And began to secrete large amounts of bacteria overflow
