摘要
利用河南省农业气象产量预报业务系统(WAPFOS),分析了夏玉米产量与光照、降水、气温等影响因子的关系,结果表明,旬降水量、旬日照时数和旬平均气温与夏玉米产量关系密切,是直接影响产量的重要因素。在此基础上,建立了预报模型。
Using Henan agrometeorological yield forecast system, we analyze the relation between yield of summer corn and the influence factors such as sunlight, precipitation, temperature, etc. The result indicates that precipitation, sunlight time and mean temperature are the key and direct factors that influence corn yield. And based on the conclusion we develop a forecast model.
