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。
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.
