1997～1998年度沿海大麦区的生产受到连续阴雨、涝渍的影响，大麦长期处于水分饱和或近饱和状态的土壤环境中，根系的主要分布深度内形成一层暂时的滞水层，涝渍致使大麦苗弱黄、分率力下降、成穗数不足，早衰现象明显，灌浆期缩短，千粒重下降，成熟期较历年早5～7d。大差减产 The production of the coastal barley area from 1997 to 1998 was affected by continuous rain and waterlogging. Barley was in a soil environment with saturated or nearly saturated soil for a long time. A temporary aquifer was formed within the main distribution depth of the root system. Barley seedling weak yellow, the rate of decline in force, lack of spikes, premature aging obvious phenomenon, filling period shortened, grain weight decreased, maturity of 5 ~ 7d earlier than the calendar year.
