The effects of different conditions (conventional mode, low temperature and quasi - low temperature) on the germination energy and germination rare of high quality paddy with different moisture contents storage within two years were studied by the test of simulation environment of large grain warehouse. The samples were taken from the upper, middle and lower layers of the paddy bulk in each of the quarter of the warehouse. The results showed that the moisture content decreased with the time, at last stopped between 12.0%～14.0%, which was not significant with the storage condition. The change range of germination energy was generally greater than that of the germination rate, but their change trends were basically the same. The variation of germination energy was more obvious, ie, the order of the change range of germination rate was the conventional storage> quasi - low temperature storage> low temperature storage, and the germination rate of the upper layer decreased obviously with the storage time, while the middle and the lower layer changed little. After comparing the reduction of germination rate of the paddy with two kinds of moisture content stored for two years in three different storage conditions, the result showed that the effect of moisture content was insignificant on the paddy stored in low temperature and quasi - low temperature environment, but the in conventional mode, the reduction of germination rate of the paddy with high moisture content (≥16.0%) decreased more than that with normal moisture content (≤14.7%).
