中文摘要: 以位于河南省南部地区的驻马店市为研究区域,利用1961～2003年驻马店市冬小麦播种期内气象观测资料,采用相关分析等数理统计方法对气候变化对冬小麦播种期的影响进行分析,结果表明:在河南南部地区,传统播种期内气温逐渐升高;气候适宜冬小麦播种期逐渐推迟;传统播种期内降水量有所减少。并利用1981～2003年驻马店市冬小麦作物观测资料进一步分析了按照传统观念播种小麦存在的弊端。从而得出结论:在河南南部地区,冬小麦的播种必须打破传统的种植观念,适当晚播,才有利于冬小麦产量的进一步提高。
中文关键词: 气候变化，冬小麦，播种期
Abstract:Based on the weather data in the period of seedtime for winter wheat from 1961 to 2003 in the Zhumadian, Henan Province, a correlation analysis is made. The result shows that the temperature of conventional seedtime in the southern area of Henan Province gradually rises. The suitable seedtime for winter wheat is gradually postponed. Rainfall during the period of conventional seedtime has decreased. The conclusion is that the output of suitable late seeding winter wheat will be increased.
