涝渍灾害是棉花生产中面临的重要自然灾害之一,长江流域棉花蕾期常遭遇多雨天气而产生涝渍灾害。在盆栽条件下,以华棉3109为试验材料,研究了不同涝害胁迫7 d(T1处理)和14 d(T2处理)对棉花生长和产量特性的影响,正常灌水管理作为对照(CK)。结果表明,在涝渍胁迫处理期间,棉花叶片SPAD值、株高、绿叶数、倒四叶功能叶叶面积、开花数、蕾数、结铃数、果枝数和果节数均表现为:CK>T1处理>T2处理。在处理结束之后(花铃期),受涝渍胁迫棉株株高、茎粗、蕾数、开花数、结铃数、果枝数和果节数等指标都相继出现快速补偿性生长现象。但是随着涝渍胁迫时间的增加,棉花蕾铃脱落率升高,成铃率下降,最终产量构成因素和单株籽棉产量呈下降趋势
