【摘要】 为了探索平原湖区易涝易渍耕地种植夏大豆的排水管理 ,选择大豆关键生育期—花荚期进行了不同水处理试验 ,研究了夏大豆不同受渍胁迫对农艺性状、产量及品质的影响。结果表明 ,受渍胁迫引起大豆单株粒数、单株荚数、单株粒重、百粒重等降低 ,从而导致减产。随着受渍时间的延长 ,减产幅度增大 ;籽粒中粗脂肪含量增加 ,粗蛋白含量下降 ,但是 ,各受渍处理间两者总含量差异不明显。更多还原

【Abstract】 In order to discuss on drainage management of summer soybean field which is easy to meet with surface and subsurface waterlogging, to select key growth phrase that is period of soybean with flowers and pods, tests of some different water treats was done, influences upon agronomy properties and yields as well as qualities of soybean was studied in different degree of subsurface waterlogging in period. Results show that pellet amounts, pod quantities and pellet weights of per plant soybean as well as weights of per 100 pellets decrease because of subsurface waterlogging stress, and led to reduction of the crop yield. Reduction degree of soybean yield increases, coarse fat content in soybean seeds raises, and coarse protein content in soybean seeds reduces along with the time extension of subsurface waterlogging stress. But there aren’t marked differences of the sum of coarse fat and coarse protein content in soybean seeds among the different waterlogged treatments.更多还原
