前言小麦锈病在全国范围内来说是麦的最严重病害。特别是在雨水较勤气候湿热的地方锈病就成为麦的致命性灾害,在我国广大的麦田里每年都有程度不同的锈病发生,每年都造成减产20～30％,个别地区减产额高达60～80％,在东北地区1950、1952、1956的几个年份发生的最普遍,程度也比较严重,因此麦的锈病已成为小麦增产的一个最重要的关键课题,往年因部分地干旱锈病的发展受到了一定的限制,但目前灌溉事业的发展,大面积的土地进行了充分的灌溉,肥料也比较充分,因此就给锈病的发生造成了极好的发生条件,锈病有叶锈、条锈、杆锈三种,近年来杆
Introduction Wheat rust is the most serious disease of wheat across the country. Especially in wet and rainy places where climate is hot and humid rust has become a fatal catastrophe of wheat. In our vast fields of wheat every year there are degrees of rust occurring each year, causing a 20 to 30% reduction in production and in some areas a yield reduction of up to 60% 80%. The most common and severe occurrence occurred in several years in 1950, 1952 and 1956 in the Northeast. Therefore, wheat rust has become one of the most important key issues for wheat yield increase. In the past years, the disease was partially affected by the development of dry rust However, at present, the development of the irrigation industry, the large area of land has been fully irrigated and the fertilizers have been relatively sufficient, thus giving rise to excellent conditions for the occurrence of rust. Rust rust, leaf rust, Three kinds of rust, in recent years pole
