| 摘 要： | 根据豫南雨养区方城、西平两县1995-2008年的夏玉米单产和同期气象资料,分析了该区生长期间气温、降水量、日照时数等气象因子对夏玉米气象产量的影响。结果表明,水分影响夏玉米生育的全过程,与光照时数相比,气温显著影响产量,6月、8月的降水量、7月的气温是影响夏玉米产量的关键气象因子。 |

| Abstract: | Based on the data of summer maize yield and agricultural climate information in Fangcheng and Xiping counties (rain-feed region) of southern Henan province from 1995 to 2008,the effects of climate factors (temperature,rainfall and illumination hour) on the meteorological yield of summer maize were studied.The result showed that the rainfall was the main factor affecting the maize production during the whole maize growing period,followed by the temperature,and then the illumination hour.The rainfall in June and August and the temperature in July were the key factor affecting the summer maize yield. |
