2000—2018年舞阳县气象因素对冬小麦产量的影响

Effect of Meteorological Factors on Winter Wheat Yield in Wuyang County from 2000 to 2018

根据2000—2018年舞阳县小麦生长期间的气象资料及小麦产量资料,分析气象因素之间以及气象因素与小麦产量的相关性。结果表明,各月降水量与光照之间有很强的负相关;降水量与气温之间负相关不明显;光照与气温之间成正相关。降雨量和光照对产量的影响较小,温度对产量有较大影响。因此,温度最有可能成为决定产量的主要因素。该试验研究结果为未来冬小麦持续高产提供了理论基础。

Based on the meteorological data and wheat yield data during wheat growth period in Wuyang County from 2000 to 2018,the correlation between meteorological factors and wheat yield was analyzed.The results showed that there was a strong negative correlation between precipitation and light;there was no significant negative correlation between precipitation and temperature;there was a positive correlation between light and temperature.Precipitation and light had little effect on yield,while temperature had greater effect on yield.Therefore,temperature is most likely to be the main factor determining yield.The results provide a theoretical basis for sustainable high yield of winter wheat in the future.
