Abstract: In order to reveal the mechanisms of the influences of meteorological factors on maize yield and its components, a two-year field experiment on ‘Jidan 27’ was conducted under various sowing dates in Jiamusi Agricultural Meteorological station basin in 2012 and 2013. And the relationship between meteorological factors and maize yield as well as its components was investigated and analyzed based on the test of the adjustment of sowing dates to the change of meteorological factors at the growth stage, which would provide the theoretic foundation on how to defense the stress of negative meteorological factors so as to realize high maize yield. The results showed that the correlation between yield components and many meteorological factors at different growth stages was significant. The average daily rainfall during shooting stage to big trumpet stage was a limiting factor on maize yield, which could affect ear barren tip, seeds per ear and strain grain weight. During silking stage to milk stage, the temperature (average daily temperature, maximum daily temperature and minimum daily temperature) was a limiting factor that the seeds per ear and the strain grain weight, except the ear barren tip, would increase along with the increase of it. And a significant negative correlation between the average daily sunshine duration and the ear barren tip was showed during big trumpet stage to tasseling stage. That was to say, the ear barren tip reduced with the increase of the average daily sunshine duration in this term. The average daily relative humidity affected the increase of seeds per ear and strain grain weight during milky stage and maturity stage. The results obtained here suggest that the best sowing time of ‘Jidan 27’ should be early to mid-May in Jiamusi; the average daily rainfall in late June and early July and the temperature (average daily temperature, maximum daily temperature and minimum daily temperature) in late July and early August would be limiting factors on maize yield increase; seeds per ear would be a main limitation on higher yield under the conditions of density and cultivation management designed in this test.
