摘　　要：对来自河南产区仓储烟叶中的主要霉菌进行了分离、鉴定,并测定了防霉剂对优势霉菌的抑制作用。结果表明,河南烟叶样品中霉菌数量以曲霉最多,其次是青霉。山梨酸钾、丙酸钙、双乙酸钠、脱氢醋酸钠、对羟基苯甲酸乙酯和富马酸二甲酯对黄曲霉、黑曲霉和桔青霉这3种优势霉菌均有明显的抑霉作用。The dominant mold fungi isolated from stored Henan tobacco leaves were identified, and the control effects of fungicides against those fungi were detected. The results showed that Aspergillus was the main dominant fungi, Penicillium the next. Sorbic acid potassium, calcium propionate, double acetic acid sodium, dehydrogenated sodium acetate,4-hydroxy-benzoic acid ethyl ester and dimethyl fumarate （DMF） showed obvious control effects against dominant mold fungi ,Aspergillus niger,Aspergillus flavus and Penicillium citrinum.
