摘要: 利用1980-2010年辽西地区6个农业气象观测站春玉米发育期和玉米产量数据,采用气候倾向率法和相关分析法分析了辽西地区春玉米发育期的变化特征,并研究了春玉米发育期对产量的影响。结果表明:1980-2010年辽西地区6个观测站春玉米抽雄-开花期和开花-乳熟期日数变化趋势一致,其余发育期日数变化趋势不同;建昌站和绥中站春玉米各发育期日数变化显著,除阜新站外,其余5个站春玉米全生育期日数均呈增加的趋势,其中彰武站全生育期日数增速为5.00 d/10 d,建昌站全生育期日数增速为7.03 d/10 d,绥中站全生育期日数增速为6.57 d/10 d,均通过了0.01水平的显著性检验。辽西地区各站春玉米发育期日数距平变化较大,不同阶段发育期日数距平的变化趋势不同,1980-2010年春玉米各发育期日数均呈由负距平转为正距平的变化。

Abstract: Based on observed data at 6 agricultural meteorological stations and spring maize yield data in the western Liaoning province from 1980 to 2010, variation of spring maize during growth period and its impact on yield were analyzed using methods of a climate trend rate and a correlation analysis.The results indicate that variation of the number of days during tasseling to flowering stage and flowering to milky maturity stage for spring maize has same trends at six stations of the western Liaoning province, while it is not the same in the other stages.Variation of number of days during different stages for spring maize is significant in Jianchang and Suizhong stations.The number of days of whole growth stage for spring maize is in an increasing trend except in Fuxin station.The trend rate is 5.00 days per decade in Zhangwu station, 7.03 days per decade in Jianchang station and 6.57 days per decade in Suizhong station, and they all pass through a significance test of 0.01 level.Anomalies of days of whole growth stage for spring maize change obviously in all stations of the western Liaoning province, and they are different in different growth stages.Anomalies of days of various growth stages change from negative to positive during 1980 to 2010.

Key words: Spring maize, Growth stage, Yield, Climate trend rate
