一、小麦锈病1.症状。小麦锈病有条锈病、叶锈病、秆锈病3种。这3种锈病的病原菌都属于担子菌类,孢子成熟遇到轻微气流就会向外飞散传播,可被刮至500~4 300米高空,被吹送到几百千米以外,导致小麦受害。小麦感染锈病后,先是叶片或茎秆表面出现褪色斑点,尔后长出黄色或红褐色的粉疱(即夏孢子堆),后期又长出黑色的疱斑(条锈、叶锈)或粉疱(秆锈),即冬孢子堆。小麦锈病的症状可总结为:条锈成行、叶锈乱,秆锈是个大红斑。
First, wheat rust 1. Symptoms. Wheat rust stripe rust, leaf rust, stem rust 3. The pathogens of these three kinds of rust belong to the basidiomycetes. When the spores mature, they encounter slight air currents and spread outwards. They can be scraped to the altitude of 500-4,300 meters and blown to hundreds of kilometers away, causing the wheat to suffer. Wheat infected with rust, the first leaves or stalks appear faded spots, and then grow yellow or reddish brown blisters (ie, summer spores), and later grew black blisters (stripe rust, leaf rust) or pink blisters (Stalk rust), that is, winter spore reactor. The symptoms of wheat rust can be summarized as: stripe rust, leaf rust chaos, stalk rust is a big erythema.
