濮阳冬小麦产量预报与气象条件分析

Analysis on Winter Wheat Yield Prediction and Meteorological Conditions in Puyang City

将濮阳市30年冬小麦产量序列分解为趋势产量和气象产量,用气象产量与历年冬小麦生育期间光、温、水气象因子进行相关普查,得出一批影响冬小麦气象产量优势相关气象因子,并建立冬小麦气象产量趋势预报和订正预报模式,统计检验和试报结果误差均在允许范围内,为濮阳市冬小麦产量监测和农业生产提供科学依据。

The winter wheat yield sequence in Puyang City in recent 30 years was divided into trend yield and metrological yield.A relevant survey was conducted on the relationship between yield and meteorological factors during winter wheat growth period.The meteorological yield trend prediction and correcting prediction model of winter wheat was established,which will provide scientific basis for winter wheat yield monitoring and agriculture production in Puyang City.
