| 摘 要： | 利用河南省林州市和泛区农业气象观测站1993—2013年及正阳县农业气象观测站1993—2008年的大豆生育期观测资料和同期气象观测资料,通过数理统计、标准化处理和通径分析等方法分析河南省气候变化对大豆生长发育的影响。研究表明:河南省大豆播种期有逐渐提前的趋势,全生育期日数和各生育期间隔日数有增加的趋势;从北到南,播种期、出苗期和开花期逐渐提前,成熟期有所延长;大豆生育期日数有延长的趋势,南部的趋势比北部的明显。从北到南,各生育期同期降水量增多的趋势逐渐明显,日照时数减少的趋势逐渐减弱,平均气温增长的趋势逐渐减弱。河南省北部地区日照时数和平均气温的变化对大豆生育期有较大的影响,中部地区降水量和平均气温的变化对大豆生育期有较大的影响,南部地区平均气温是主要影响因子。

| Abstract: | ased on soybean growth period observational data and meteorological data of Linzhou and Fanqu stations from 1993 to 2013 and Zhengyang station from 1993 to 2008 in Henan province, using the methods such as mathematical statistics, standardized processing and path analysis, the effect of climate change on soybean growth period in Henan province were analyzed. Results showed that soybean seeding time of Henan province occurred early, the whole growth days and each growth period days were in increasing trend. From north to south, the seeding, emergence and flowering periods became early gradually, maturity period was delayed. Soybean growth days were in extending trend, and the tendency in south was more obviously than that in north. During each growth period, increasing trend of precipitation was gradually obvious, the reducing trend of sunshine and the increasing trend of mean temperature were gradually weaken from north to south. The variation of sunshine and mean temperature had larger effect on soybean growth period in northern Henan, the variation of precipitation and mean temperature had larger effect on soybean growth period in middle Henan, the mean temperature was the main factor affected soybean growth period in southern Henan. |
