摘 要 ：采用正交组合设计，研究了洪涝中各因素对棉花产量、产量构成因素及其品质的影响。结果表明:(1)淹水天数、淹水深度、淹水生育期对棉花产量有显著影响，各因素对棉花产量的影响主要是减少了总铃数，而且在淹水条件下棉花品质降低。(2)棉花蕾期对淹水最敏感，减产最严重。并且其棉花品质(纤维整齐度、平均纤维长)显著降低。

Abstract:Effects of flooding at different developing stages on cotton yield，yield components and cotton qualities were studied in the experiment designed by orthogonal combination. The results are as follows:(1)The cotton yield was affected significantly by days，depths and developing stages of submergence
