【Abstract】 In the autumn of 2021, abnormal weather occurred in the northern Liaoning region, and the local corn suffered from mildew and excessive mycotoxins. In order to understand the local corn quality and its influencing factors,investigations were carried out on local farmers, grain quality supervision units and purchasing companies. The results showed that the average moisture content of corn was 22.6% at the end of December. The average content of “mildew” corn ears is 2.5%. The corn ear mold content of the cutting sample is high. The proportion of samples with moldy grain content, DON content, and zearalenone content exceeding the standard is high. The main influencing factors are the abnormal weather from september to november, the planting scale and storage mode of corn, and the knowledge and understanding of scientific grain storage.更多还原
