新疆北疆近年来迅速蔓延着一种当地称为细菌性条斑病的小麦病害。1980年6—7月,我们在石河子地区、昌吉州和伊犁州共8个县(团场)实地调查50块麦田共一万多亩,所调查的田块均感病,发病株率均在46—100％,平均为85％,减产15—20％,其中伊犁州新源县东方红农场,小麦平均减产30％。据观察,本病主要为害叶片,其次是叶鞘、茎秆和穗部。被害叶初呈水渍状半透明短条斑,随后沿叶脉间向上、下扩展,成条状或互相连接成不规则形病斑,最后呈油渍发亮褐色枯死斑。有雨露时,病组织中可渗出黄白色菌脓,菌脓干缩后呈黄色胶粒。
In recent years, Xinjiang’s northern Xinjiang has rapidly spread a type of wheat disease known locally as bacterial leaf streak. From June to July 1980, we surveyed 50 hectares of 50 wheat fields in 8 counties (farms) in Shihezi, Changji and Ili prefectures. All the plots surveyed were susceptible and the incidence rate was 46-100% with an average of 85% and a reduction of 15-20%, of which Donglihong Farm, Xinyuan County, Yili Prefecture, with an average yield reduction of 30%. It is observed that the disease is the main damage leaves, followed by leaf sheaths, stalks and spikes. Victims of early leaves showed water-like translucent streaks, followed by up and down along the veins, extending into a strip or connected to each other into irregular shaped lesions, the last oil stain brown dead spots. When there is rain, the yellow tissue can be exuded yellow and white pus, bacterial pus shrinkage yellow rubber particles.
