摘要
在浙江省农村农家贮藏稻谷中,定点每月采集稻谷样品,共分离到37个属的真菌(不包括酵母菌)。其中曲霉属(Aspergillus spp.)、青霉属(Penicillium spp.)、镰孢霉属(Fu-sarium spp.)、弯孢霉属(Curvularia spp.)、链格孢霉属(Alternaria spp.)为优势菌。系统调查研究表明,我省农家贮粮早晚稻谷在真菌种类和数量上有较大差异,在不同的地区及贮藏方式中,真菌的种类基本一致,但其群体有着明显的变化规律,新收入库的稻谷以田间真菌的检出率和带菌量为高,从贮藏的第二个月开始,贮藏真菌有明显增长,并随外界条件出现变化,田间真菌则相应减少。贮藏方式和环境条件的不同,真菌的数量及霉变损失程度亦呈明显差异。
Paddy samples were monthly taken from 9 farmer's home storesin 3 villages representing different types of rice storage in ZhejiangProvince.Based on careful examinations 37 genera of fungi were iden-tified,of which Aspergillus,Penicillium,Fusarium,Curvularia and Alte-rnaria were the dominant genera.Systemic investigations indicated thatthe kinds and numbers of fungi isolates from rice grains were notsimilar.The changes of their populations remarkably varied with geo-graphic regions and the ways of storage.Survey also showed that“fieldfungi”were at their maxiamum at the beginning of storage.Fromsecond month,howerver,“storage fungi”increased sharply and fluc-tuated with the variation of environment conditions,while“field fungi”were reduced.The amount of fungi and losses of rice grains due tofungal infection were significantly different with the ways of storageand the environments.
