小麦在我省的面积和产量都仅次于水稻。但锈病一直威胁着小麦生产,如1962—1966年和1972—1981年小麦条锈病都曾连年流行。据不完全统计,一般流行年减产1亿斤左右,大流行年减产3亿斤以上。因此,能否切实有效地控制住条锈病流行,将是我省小麦生产能否持续高产稳产的重要因素。 The area and production of wheat in our province are second only to rice. However, the rust has been a threat to wheat production, such as wheat stripe rust in 1962-1966 and 1972-1981. According to incomplete statistics, the annual epidemic rate has dropped by about 100 million kilograms and the annual pandemic has reduced by 300 million kilograms or more. Therefore, whether the epidemic of stripe rust can be controlled effectively and effectively will be an important factor for whether the production of wheat in our province can sustain high and stable yield.
