| 摘 要： | 通过田间试验，建立了膜下滴灌棉花CWSI和水汽饱和差VPD的定量关系，确定了棉花各生育阶段CWSI下基线的特定表达形式。对膜下滴灌条件下棉花生长发育、光合动态与根系分布规律以及不同水分处理的耗水量、产量与品质指标进行了观测。对不同水分处理棉花的CWSI进行了定期观测，得到了棉花CWSI与棉花耗水量的关系。 |
| 关 键 词： | CWSI 膜下滴灌 棉花 作物需水量 |

| Abstract: | A field experiment was conducted to determine the relationship between the CWSI (crop water stress index) and VPD (vapor pressure difference) of drip-irrigated cotton under membrane, and the special expression forms for the lower baselines of the CWSI curve at different growth stages of cotton. The indexes of growth, photosynthesis dynamics, root distribution rules, the water depletion, and the qualities and yields for different water treatments of drip irrigated cotton under membrane were observed during the whole growing stages. The CWSI of different water treatment cotton was observed periodically and the relationship between CWSI and crop water depletion was established. |
| Keywords: | CWSI (crop water stress index) drip irrigation under membrane cotton crop water requirement |
