对辽宁省16个站点1980~2005年的玉米物候资料分析表明,玉米播种与出苗微弱提前,但成熟明显推后,导致玉米生育期明显延长;玉米播种期、出苗期、成熟期和全生育期均与温度呈显著负相关,除播种期外,玉米各个物候期与降水则呈显著的正相关;年平均气温的升高导致玉米生育期缩短,年降雨量的减少导致生育期延长.因此,未来气候暖干化将对玉米生长、质量和产量产生重大影响.

The phonological data at 16 stations of Iiaoning Province from 1980 to 2005 were analyzed. The results showed that the sowing and seedling emergence of maize appeared slightly earlier. But the mature was significantly postponed, which led to longer growing season. The stages of sowing, seedling emergence, mature and growing season all showed a significant negative correlation with temperature. Except sowing stage, all phenological stages of maize showed a significant positive correlation with precipitation. The increase of annual average temperature caused the shortening of maize growth stage. The decrease of annual precipitation brought about the longer growth stage. Therefore, warming and drought of the future climate would have fatal effects on the growth, quality and yield of maize.
