| 摘 要： | 在长江中下游平原湖区，棉花生长期间适逢雨季，常受多过程涝渍胁迫。通过测坑试验发现棉花受多过程涝渍胁迫后减产严重，涝渍程度可用涝渍因子(SFW、SEW50、SFEW50)来描述，棉花相对产量(Ry)与涝渍因子(SFW、SEW50、SFEW50) 之间存在着显著的线性关系。 |
| 关 键 词： | 涝渍胁迫 减产 相对产量 涝渍因子 |

| Abstract: | Usually, cotton is stressed by multi-stage water logging during growth stages in the plain-- lake areas at the middle and lower reaches of the Yangtze River. Through pilot experiment, it is found that the cotton yield is obviously influenced by multi-- stage water logging; the degree of water logging can be described by the water logging factors such as SFW, SEW50, and SFEW50 ; there is a significant linear relationship between the cotton relative yield Ry and the water logging factors such as SFW, SEW50, and SFEW50. |
| Keywords: | water logging stress reduction of yield relative yield water logging factor |
