在浙江省采集仓贮稻谷及大米样品,共分离到真菌17属48种(不包括酵母菌)。其中:曲霉属(Aspergillus)18种,青霉属(Penicillium)10种,镰孢霉属(Eusarium)4种。研究表明:在浙江省地区之间,贮粮真菌种类无明显差异。稻谷加工成大米后,籽粒表面带菌量及内部带菌率均明显下降,其真菌区系以贮藏真菌为主。稻谷在贮藏前以田间真菌为主。贮藏1—4个月的稻谷因贮藏真菌的种类、数量明显增长,而田间真菌的种类和数量仍保持在较高的水平上,其表面带菌量及谷粒带菌率处于高峰期;贮藏1年以上的稻谷,其主要带菌种类为贮藏真菌,带菌量及带菌率明显下降。早籼谷和晚粳谷在相同贮藏条件下其带菌种类和数量基本一致。
A total of 48 species (excluding yeast) of 17 genera were isolated and collected in Zhejiang Province. Among them, 18 species of Aspergillus species, 10 species of Penicillium species and 4 species of Eusarium species. Studies have shown that: in Zhejiang Province, there is no significant difference in the type of grain storage fungi. After rice was processed into rice, the amount of fungi on the surface of the grain and the rate of internal fungi decreased significantly, and the fungal flora mainly contained fungi. Rice is dominated by field fungi before storage. The amount of stored fungi in the paddy rice stored for 1 to 4 months increased significantly, while the number and type of fungi in the field remained at a high level. The amount of fungi on the surface and the rate of grain carried in the corn peaked at 1 year The above paddy, the main carrier species for the storage of fungi, the amount of fungi and carrier rate decreased significantly. Early indica Valley and late japonica valley in the same storage conditions, its species and quantity are basically the same.
