摘　　要：以新收获小麦为研究对象,检测2020—2023年小麦籽粒不完善粒、真菌毒素含量等指标,分析真菌毒素污染情况、不完善粒与真菌毒素含量的关系、天气对小麦真菌毒素含量的影响。根据真菌毒素污染情况,重点以2023年新收获小麦为研究对象,结果表明,不完善粒与DON含量之间存在正相关性,相关系数R^(2)=0.930 5;不完善粒与ZEN含量之间存在正相关性,相关系数R^(2)=0.992 3;DON和ZEN含量之间存在正相关性,相关系数R^(2)=0.812 4;天气对新收获小麦真菌毒素含量影响较大,小麦扬花期至收获期连阴雨天气是造成小麦DON和ZEN含量高的主要影响因素。This study analyzed newly harvested wheat from 2020 to 2023,focusing on defective kernels,mycotoxin content,and related factors.Mycotoxin contamination,the relationship between defective kernels and mycotoxin levels,and the influence of weather conditions were examined.According to the status of mycotoxin contamination,with a particular focus on newly harvested wheat from 2023,the experimental results showed significant positive correlations:defective kernels and DON(R^(2)=0.9305),defective kernels and ZEN(R^(2)=0.9923),and DON and ZEN(R^(2)=0.8124).Weather had a strong influence on mycotoxin levels in newly harvested wheat,and continuous rainy weather from flowering to harvesting was the main influence on high DON and ZEN levels in wheat.
