Agricultural Strategy for Drought Resistance and Suggestion of Ramie Studies

缺水是限制作物生产能力、困扰农业发展的全球性问题。苎麻是我国特色经济作物,抗旱和水土保持能力强,是有效利用南方干旱坡地的先锋作物,但苎麻产量与品质受干旱影响严重。研究苎麻应答干旱胁迫的机制及其农业应对策略,将为苎麻稳产高产提供理论与技术支撑。文章在探讨干旱胁迫影响植物生产的一般性规律基础上,总结了苎麻抗旱研究的主要进展与问题,以期为苎麻抗旱育种与生产提供依据。

Water shortage is a global challenge that constrains crop productivity and agricultural development.As a traditional and predominant industrial crop in China,ramie(Boehmeria nivea) is identified with high drought resistance and high water and soil conservation capacity.Ramie is also considered as a pioneer plant for cultivating on poor and arid hillside in south China.However,the yield and quality of ramie are seriously affected by drought.Therefore,it is important to unravel the responding mechanism of ramie under drought stress and propose agricultural strategies to address the challenges.In this article,general rules of the effects of drought on crop production were discussed and major progress and problems in ramie research field were summarized for providing foundation for ramie breeding and cultivation.
