Abstract: Aiming to research the spring maize adaptation in Northeast China to climate change and provide feasible strategies to government, in this paper, two sowing experiments, including stage sowing and geographical-stage sowing, were performed. Two experimental stations, Harbin in northern region of Northeast China and Jinzhou in southern region of Northeast China, are selected to carry out the stage sowing experiments. Two predominated varieties of spring maize, ‘Jiulong 8’ in Harbin and ‘Nonghua 101’ in Jinzou, are selected to plant in these two stations, respectively. Meanwhile, the geographical-stage sowing experiment was performed in Harbin and Jinzhou simultaneously with the spring maize of ‘Jiulong 8’. In the stage sowing experiment, normal sowing date was designed as CK in both two experimental stations, and other two plans were done with later sowing dates by 10 days and 20 days, respectively. While in the geographical-stage sowing experiment, normal sowing date in Harbin was selected as CK, and other three plans were performed with earlier or later sowing dates in Jinzhou site to represent future climate warming situations, expressed as CW1-CW3. Compared between CK and CW1-CW3, the impacts of climate warming on growth condition and yield of spring maize are studied. The results show that it is not good for spring maize in Harbin site if the sowing date is much later than normal. However it has no obvious impacts in Jinzhou site. If keeping the present variety, growth periods of spring maize are shortened under all three climate warming situations compared with CK. The shorten days are from 12 days to 20 days among three climate warming situations. The increasing trends are shown in 100-kernel weight and yield in all designed future climate warming situations, with the increase of 83-188 g/m2.
