摘要
在测坑中于大豆(Glycine max)开花期进行持续涝渍胁迫试验,结果表明:大豆开花期受涝渍胁迫时间愈长,大豆减产愈严重,大豆受涝2 d～10 d,减产11.19%～42.84%。大豆不同生育阶段受涝渍胁迫,以苗期受灾最轻,开花期受灾最重。在低产田中,大豆经常遭受涝渍胁迫,减产高达90%以上。分析表明,涝渍水深(SFEW_(30))与大豆相对产量(Ry)存在着很好的线性负相关关系。
Waterlogged stress experiments were carried out in test-pits in soybean(Glycine max) pods bearing.The results showed that the more of the time of soybean to suffer from waterlogged stress,the more reduction of the yield.There were 11.19%~42.84% yield reduction in the stage when soybean suffered from surface waterlogging for 2 to 10 days.In those lower output cropland,soybean often met with waterlogged stress and output reduction amounted to 90%.Analysis showed that there was a close,linear and negative corr...
