玉米涝渍灾害研究进展与展望

综述近年来国内外玉米涝渍灾害的最新研究进展，对涝渍指标和涝渍对玉米生长发育、产量及构成要素、生理生化过程的影响以及基于作物模型的涝渍影响研究进行总结与评述。目前，玉米涝渍灾害评定标准尚未统一，涝渍指标多以降水量或土壤含水量为基础，需以土壤水分平衡为核心，综合多种因素进一步深入研究。加强涝渍对玉米影响的机理研究，增强现有作物模型对灾害影响的模拟能力是作物模型发展的方向。

Research Progress and Prospective of Waterlogging on Maize

Based on summing up the research history and present situation of waterlogging on maize, this paper reviewed the waterlogging indexes, effects of waterlogging on maize development process, on yield and its compared factors, on biochemical and physiological process, and the quantitative assessment methods by crop model. Up to now, there was no universally accepted standard of waterlogging for maize, and most of the indexes that had been built on the basis of precipitation or soil moistures. Around the soil moisture balance, considering multiple associated factors comprehensively, more studies would be performed in the future. Furthermore, strengthen research on the influence mechanism of waterlogging on maize, improve the ability of existing crop models to simulate the impact of disasters were aspects of its future.
