小麦腥黑穗病是我国的植物检疫对象。据调查,此病已蔓延到全省各地。80年代前期只在辽宁局部地区发生,目前大部分地区均有发生。发病严重的地块病穗率高达30％左右,造成严重减产。腥黑穗病不仅减产,且病粒有毒,人们食用了带病菌的面粉便会中毒。近几年我省小麦种植面积迅速扩大,每年所需种子数量很大,应严格把住种子质量关,切实有效地采取措施,防止腥黑穗病的危害。
Wheat’s smut is our country’s phytosanitary target. According to the survey, the disease has spread to all parts of the province. In the early 1980s, only in some areas of Liaoning occurred, most areas have occurred. Severe diseases of the disease panicle rate as high as 30%, resulting in serious cuts. Ticks not only reduce production, and the particles are toxic, people eat the flour with bacteria will be poisoned. In recent years, the area under wheat cultivation in our province has rapidly expanded, and the number of seeds required for each year is very large. The quality of seeds should be strictly controlled and effective measures should be taken to prevent the harm caused by the disease.
