| 摘 要： | 利用测坑试验研究了棉花花铃期涝渍相随对产量及品质的影响。结果表明 ,棉花花铃期受涝渍相随的影响很大 ,不同涝渍处理棉花产量差异显著 ;涝渍胁迫对棉花品质有一定影响 ,但处理间差异不大。通过数学模型定量分析表明 ,涝渍连续过程中涝和渍对作物的影响程度不同 ,涝对棉花产量的影响远比渍大 ,渍前受涝越严重 ,减产越严重。 |
| 关 键 词： | 涝渍相随 棉花 花铃期 |

| Abstract: | Influence of subsurface waterlogging followed by surface waterlogging on yield and quality of cotton was studied by test-pit experiments at flowering and boll setting stage of cotton. The results showed that the difference was significant in yield among different experimental treatments; waterlogging stress had a certain influence on quality of cotton, but there was only a little difference among treatments. Quantitative analysis by mathematic models showed that the degree of influence from surface waterlogging on the crop was different from that from subsurface waterlogging in continuous progress of surface and subsurface waterlogging. The influence of surface waterlogging on yield of cotton was stronger than that of subsurface waterlogging. The serious the surface waterlogging before subsurface waterlogging, the more loss of yield of cotton. |
