Maize plants were treated by the low temperature under different water conditions during seedling and tasseling periods in the artificial climate chamber to determine the impacts of low temperature, drought and their combination on maize yield in the Northeast China. Based on the results of the controlled experiment, the WOFOST model was applied to simulate the integrated impacts of low temperature and drought on maize yield.
