摘要
干旱是影响作物生长及产量的最重要环境因素,全球气候变暖使部分地区的干旱趋势加重了,为了减少干对作物生长造成的影响。本文从干旱对作物生长、光合作用、气孔、渗透调节、抗氧化系统几个方面进行了详细的阐述,为作物抗旱机理提供理论依据。
Drought is the most important environmental factor that affects crop growth and yield.Global warming has exacerbated the trend of drought in some areas in order to reduce the impact of dryness on crop growth.In this paper,the aspects of crop growth,photosynthesis,stomata,osmotic adjustment,and antioxidant system are expounded in detail from drought to provide theoretical basis for crop drought resistance mechanism.
