一.引言我国近几年来常有内涝灾害发生,而且大都发生在长江淮河流域及其他低洼地区。1954年由于降雨集中,排水不良,在长江淮河流域便发生了面积广大为时二个多月的内涝.在内涝地区以水稻受害面积最大,受害轻微者减产,受害严重者全部死亡。因此我们必须加强关于水分过多对作物的影响的试验研究,掌握农作物对涝害的反应和受涝害最严重的生长发育时期。一方面了解植物的耐涝规律,为防止涝害的措施提供资
I. Introduction China’s frequent occurrence of waterlogging disaster in recent years, and most occurred in the Yangtze River and other low-lying Huaihe River Basin. Due to the concentrated rainfall and poor drainage in 1954, a large area of over two months of waterlogging occurred in the Huaihe River basin of the Yangtze River. In the waterlogging area, the area affected by rice was the largest, and those who suffered slight losses were all killed. Therefore, we must strengthen the pilot study on the effect of excessive water on crops, and grasp the response of crops to waterlogging and the period of growth and development that is most affected by waterlogging. On the one hand understand the law of waterlogging plants to provide protection against floods and measures to provide funding
