摘要
濉溪县2012年夏大豆遇旱晚播,成熟期推迟,生育期略有缩短。气温略低于常年,降水少而集中,后期日照充足、温度高、温差大,有利于提高单株粒重。因而产量创历史新高,突破2250kg/hm2。
Summer Soybean of Suixi County was sowed later because of drought. Mature period was postponed and growing period shortened. Temperature was slightly lower than the former years, less precipitation and more concentration. The ample sunshine in late growth stage, high temperature and large temperature difference were beneficial to improving the grain weight per plant. Thus the yield reached a record high, breaking through 2 250 kg per ha.
