摘 要:稻谷2018年11月收购后用高大平房仓进行储藏,2019年1~7月间对储藏粮堆中五点三层15个位置稻谷的温度、含水量、霉菌量及优势霉菌进行监测,探讨了实仓稻谷粮堆中霉菌区系的演替规律.结果表明:储藏期间粮温随气温回升而逐渐升高.粮堆中各位置稻谷的水分在储藏期间存在轻微波动,但均低于稻谷安全储藏水分.1~4月,稻谷霉菌量整体表现出下降趋势,4~7月上层稻谷的霉菌量下降或基本保持不变,中、下层稻谷的霉菌量整体上升或基本保持不变.1月稻谷中优势霉菌主要为黄曲霉和镰刀菌,4月和7月优势霉菌主要为黄曲霉,但7月粮仓有一位置的优势霉菌转变为青霉.Paddy,harvested in November,2018,was stored in large warehouse.From January to July 2019,the temperature,moisture contents,mold contents and dominant mold of 15 locations of"five point three layers"in the stored paddy heap were monitored,and the succession law of mold flora in the stored paddy heap was discussed.The results showed that the temperature of paddy increased as atmospheric temperature increased.The moisture contents of paddy at the selected positions slightly fluctuated,but all were lower than the safety storage moisture content of paddy.The mold content of paddy generally decreased from January to April.From April to July,mold content of the upper layer generally decreased or remained constant,and mold contents of the middle and lower layers generally increased or remained constant.The dominant molds of paddy were Aspergillus flavus and Fusarium sp.in January.The dominant mold of paddy was Aspergillus flavus in April and July.In July,there was one position showing dominant mold of Penicillium sp.
