摘要
以4个玉米品种为试验材料,研究潍坊地区气候因素对夏玉米生长发育的影响。结果表明,有效积温与产量成极显著相关,生育期与产量之间的相关性不显著;玉米生育期内,随着有效积温的增加,产量提升显著;玉米灌浆速率受温度、降水、日照时数等多个因素的影响。
Four maize varieties were used to study the effects of climate factors on the growth and development of summer maize in Weifang area.The results showed that there was a significant correlation between the effective accumulated temperature and the yield,but there was no significant correlation between the growth period and the yield.During the growth period of maize,the yield increased significantly with the increase of the effective accumulated temperature.The maize filling rate was affected by many factors,such as temperature,precipitation,sunshine hours,etc.
