| 摘 要： | 试验研究了晋南地区棉花在不同生育期的水分亏缺、施肥条件下对棉花产量的影响。研究表明,棉花蒸腾量随灌水量的增加而增加,相应的产量也明显地提高,棉花产量与总耗水量呈二次抛物线关系。在相同灌水条件下,不同施肥量处理的蒸发蒸腾量差异不大,施肥量对棉花的蒸腾量影响不明显。 |
| 关 键 词： | 棉花 水分胁迫 施肥 产量 腾发量 |

| Abstract: | This study investigated the impact of moisture and fertilization deficit on cotton yield during different growth stages in Jinnan area.Studies have shown that the amount of transpiration of cotton increases with the increasing quantity of irrigation water,and the corresponding cotton yield greatly increases as well.The total water consumption and cotton yield keep a relationship of quadratic parabola.Under the same irrigation conditions,there is no big variance in evapotranspiration resulting from different fertilizer treatment,and the impact of quantity of fertilization on cotton transpiration is not significant either. |
| Keywords: | cotton water stress fertilization yield evapotranspiration |
