大豆种皮光滑,而且有蜡质层,虫害比其它作物种子差,但大豆的含油率和蛋白质高,在贮藏期间比较突出的问题是浸油红变。保持一定的低温低湿,使细菌不能正常生长和侵染,可以避免豆种红变。据试验:大豆含水量为11.5～12%,在仓库贮藏一年中的真菌生长最慢,含水量为13.5～14%,温度为5℃时贮藏290天后,仓库没有真菌的发育。真菌是贮藏期间大豆变质的最主要原因,害虫很 Soybean seed coat is smooth and has waxy layer. Insect pests are worse than other crop seeds. However, soybean oil content and protein are high, and the prominent problem during storage is immersion reddening. Maintain a certain low temperature and humidity, so that bacteria can not grow and infection, can avoid the red bean species. According to the test, the water content of soybean is 11.5-12%. The fungus growth in the storage year is the slowest, with the water content of 13.5-14%. After 290 days of storage at 5 ℃, there is no fungal growth in the warehouse. Fungi is the most important cause of soybean metamorphosis during storage, pests are very
