| 摘 要： | 针对聊城市夏玉米出现的果穗较短、秃顶严重及株籽粒重降低等原因导致的玉米产量降低，对夏玉米生育期的降水、日照、温度和相对湿度等气象因子进行了分析。结果表明，玉米减产原因主要是夏玉米播种期的强降水造成土壤湿度饱和导致烂种、开花授粉期的高温致使授粉不良，以及遇连阴雨寡照天气不能授粉所致。结合聊城市气候及玉米生产状况，提出了应对气象灾害的对策措施。

| Abstract: | According to short yield of summer maize in Liaocheng city due to short ears，severe baldness and reduced grain weight，meteorological factors such as precipitation，sunshine hours，temperature and relative humidity during growth periods of summer maize were analyzed.Results showed that main reason of maize yield reduction was soil moisture saturation caused by heavy precipitation during summer maize sowing period that lead to seed rot，high temperature during flowering pollination period lead to poor pollination and encounter continuous rain and few sunshine hours lead to no pollination.Combined with climate and corn production situation of Liaocheng city，countermeasures to meteorological disasters were also put forward. |
