选取黄淮海地区推广的10个大豆品种(中黄37、冀豆17、齐黄1号、齐黄34、齐黄35、齐黄42、菏豆19、徐豆14、郑92116、皖豆28),研究其苗期、花期和全生育期的耐涝性。结果表明,苗期、花期和全生育期淹水对大豆生长发育均造成一定影响,具体表现为叶片黄化、株高降低、生长发育延后、主根腐烂、不定根代替主根行使功能、产量降低、品质下降等,其中花期和全生育期淹水对产量影响大,苗期影响较小。在所有供试品种中,齐黄42对三个时期淹水
Ten soybean varieties (Zhonghuang 37, Jidou 17, Qihuang 1, Qihuang 34, Qihuang 35, Qihuang 42, Hedeng 19, Xudu 14, Zheng 92116, Wanu 28 ), To study its seedling, florescence and growth period of waterlogging resistance. The results showed that flooding at seedling stage, florescence stage and whole growth stage had some effects on the growth and development of soybean. The results showed that leaf yellowing, plant height reduction, delayed growth and development, rotting of main roots, adventitious roots instead of main roots, Quality decline, etc., of which flowering and the whole growth period flooding on the yield of large, small impact on the seedling stage. Among all tested cultivars, Qihuang 42 flooded in three periods
