摘要： 气候变化常常会导致小麦产量波动，5月份作为冬小麦生育的关键期，该时段气候变化对冬小麦产量影响较为显著。[目的]为了促进冬小麦产量的提升, [方法]利用宝鸡地区近16年来5月份的气温、降水、日照等气候数据，与宝鸡地区冬小麦单位面积产量进行相关分析。 [结果] [结论]结果显示：宝鸡地区冬小麦5月生育的适宜生长的气温为20 ℃左右；冬小麦单产与5月份降水量之间存在着负相关的关系，但降水量减少所带来的冬小麦增产并不是无限的；冬小麦单产与5月日照累计时长没有明显的线性相关，但产量会随光照时长逐渐增多，充足的光照对于冬小麦5月生育有重要的意义。

Abstract: Climate change often leads to the fluctuation of wheat production, and May is the key period of winter wheat growth, the climate change during this period has significant impact on winter wheat yield. To promote the yield of winter wheat, the correlation between climate data such as temperature, precipitation and sunshine in May of each year from 2000 to 2015 and winter wheat yield in Baoji were analyzed. The results showed that the suitable temperature for winter wheat growing in May in Baoji area was about 20℃; there was a negative correlation between the yield of winter wheat and the precipitation in May, but the increase of winter wheat yield caused by the decrease of precipitation was not unlimited; there was no obvious linear correlation between the yield of winter wheat and the cumulative duration of sunshine in May, but the yield would increase gradually with the duration of light, and sufficient light was significant for winter wheat growth in May.
