小麦锈病俗称“黄疸”,包括条锈、秆锈和叶锈三种。它们均以产生大量的铁锈色的夏孢子堆而得名。三种锈病在我国各主要产麦区均有发生,而在一二二团场发生为害的主要是叶锈。 锈病对小麦生产造成很大的威胁,在小麦发生锈病后,不仅病菌夺取小麦营养,减少光合作用面积,特别是由于大量的孢子堆突破小麦表皮,使麦株严重丧失水分,影响其生育和麦粒灌浆,因而使麦粒瘦秕,不仅产量低且出粉率也差。病势严重时使麦叶过早枯死,小麦停止生育。
Wheat rust commonly known as “jaundice”, including stripe rust, stalk rust and leaf rust three. They are named for producing a large number of rust-colored summer spores. Three kinds of rust disease occurred in all major wheat producing areas in our country, but the main rust that occurred in the 122 field was leaf rust. Rust disease poses a great threat to wheat production. After the occurrence of rust in wheat, not only the bacteria can seize wheat nutrition and reduce the area of photosynthesis, especially because a large number of spores heap break the wheat epidermis, causing serious loss of moisture and affecting the growth of wheat and wheat Grain filling, thus making wheat thin Shou, not only low yield and flour yield is poor. When the disease is serious, the wheat leaves die early and the wheat stops giving birth.
