| 摘 要： | 干旱是影响作物生长发育的主要非生物胁迫因素之一，水分亏缺所造成的危害超过了一切逆境因子的总和，严重影响作物产量及农业生产。作为全国重要优质棉区之一的新疆，干旱及水资源缺乏也成为棉花产业发展的重大限制因素之一，棉花种植几乎完全依赖灌溉，而棉花或棉田是否需要灌溉，可根据土壤含水量以及植株本身受旱程度特征等指标来判断。本文从棉花干旱形态变化、生长发育进程、生理生态特征、产量结构差异、土壤水分变化、气象干旱等不同方面对绿洲棉田干旱指标研究的现状和进展进行总结，并对进一步开展滴灌模式下棉田干旱发生发展过程以及干旱敏感性指标研究提出建议。

| Abstract: | Drought is one of the main abiotic stress factors affecting crop growth and development. The damage caused by water deficiency exceeds the sum of all stress factors, which had serious influence on the yield of plants and agricultural production. Xinjiang as one of the important high quality cotton areas in China , drought and lack of water resources have also become one of the major limiting factors in the development of cotton industry. Cotton planting is almost entirely dependent on irrigation. Whether cotton or cotton fields need irrigation can be judged, according to the soil moisture content and the drought degree of plant itself. In this paper, the present situation and progress of the research on drought index of cotton field in oasis were summarized, from different aspects such as change of cotton drought morphology, growth and development process, difference of yield structure, physiological and ecological characteristics, change of soil moisture, meteorological drought. Some suggestions were put forward for further research, about drought development process and drought sensitivity index of cotton field under drip irrigation with mulch in oasis. |
