陇东塬区气象要素变化对冬小麦产量影响

Analysis and countermeasure of effect of meteorology factor to winter wheat yield on Loess Plateau of Longdong area

采用回归积分法分析了陇东塬区地温、气温、降水、日照等气象要素对冬小麦气候产量的影响。结果表明:水分影响着冬小麦生育的全过程,温度对冬小麦的越冬和成熟期影响较大,气温对产量的影响比地温更为显著。同时提出了相应的农业生产措施。

This paper uses integral regression to analyze the effect of soil temperature, atmospheric temperature, precipitation and sunlight on the yield of winter wheat in the Loess plateau in Long Dong. The result shows that water affects the whole growth of winter wheat, and the temperature has rather large effect on overwintering. And atmospheric temperature affects more remarkably than soil temperature. Finally, it puts forward corresponding measure for agricultural production.
