利用济南市唯一的国家农气基本站2012-2013年度冬小麦全生育期的气象资料，探讨了冬小麦主要发育期的有利气象条件，评价气象条件对冬小麦生长和产量的影响。指出冬前气象条件适宜，墒情良好，冬小麦平均分蘖和次生根较上年较多，安全越冬。返青后至抽穗气温偏低，延长小麦分化时间，易成大穗，增加穗粒数；乳熟至收获期间天气条件利大于弊，有利于小麦灌浆和提高千粒重。

Using meteorological data of winter wheat during the whole growth period from 2012 to 2013 in national agricultural gas only in Ji'nan city,advantage meteorological conditions of winter wheat during main development period was Investigated ,the effect of meteorological conditions on the growth and yield of winter wheat was evaluated.The meteorological conditions for winter wheat was suitable ,moisture was good ,average tiller and secondary roots was more than the previous year ,winter wheat was able to safe wintering. temperature was lower after reviving to heading ,prolong the time of wheat differentiation ,easily formed a large spike ,increased grain number.Weather conditions was more advantages than disadvantages during milk to harvesting ,it was beneficial to wheat grain filling and increase grain weight.
