Abstract: To prevent the low temperature damage to early rice production and seasonal arrangement of late rice, the occurrence of spring low-temperature continuous rain and lesser fullness cold from 1954 to 2016 in Nanchang County were analyzed. The results showed that the occurrence and degree of spring low-temperature continuous rain over the past years presented a decreasing trend, which was not significant. The total number of lesser fullness cold had a significant downward trend, so did the number of severe lesser fullness cold, but the change of mild and moderate lesser fullness cold were not obvious. The current climate change is beneficial to double cropping rice production, and to ensure the safe production of early rice, reasonable arrangement should be made according to the actual weather conditions. The results could provide a basis for the dynamic assessment of low temperature damage in spring and the safe production of early rice in Nanchang County.
